openquake.hazardlib.gsim.base.GMPE
Implements the Subduction GMPE developed by Norman Abrahamson, Nicholas Gregor and Kofi Addo, otherwise known as the “BC Hydro” Model, published as “BC Hydro Ground Motion Prediction Equations For Subduction Earthquakes (2015, Earthquake Spectra, in press), for subduction interface events.
From observations of very large events it was found that the magnitude scaling term can be adjusted as part of the epistemic uncertainty model. The adjustment comes in the form of the parameter DeltaC1, which is period dependent for interface events. To capture the epistemic uncertainty in DeltaC1, three models are proposed: a ‘central’, ‘upper’ and ‘lower’ model. The current class implements the ‘central’ model, whilst additional classes will implement the ‘upper’ and ‘lower’ alternatives.

The GMPE distinguishes between rock (vs30 >= 600) and deep soil (vs30 < 600). The rake angle is also taken into account to distinguish between ‘reverse’ (45 <= rake < 135) and ‘other’. If an earthquake rupture is classified as ‘reverse’, then the hanging-wall term is included in the mean calculation.

Boore and published as “Earthquake Ground-Motion Prediction Equations for Eastern North America” (2006, Bulletin of the Seismological Society of America, Volume 96, No. 6, pages 2181-2205). This class implements only the equations for stress parameter of 140 bars. The correction described in ‘Adjustment of Equations to Consider Alternative Stress Parameters’, p. 2198, is not implemented. This class extends the BooreAtkinson2008 because it uses the same soil amplification function. Note that in the paper, the reported soil amplification function is the one used in a preliminary version of the Boore and Atkinson 2008 GMPE, while the one that should be used is the one described in the final paper.

Boore and published as “Earthquake Ground-Motion Prediction Equations for Eastern North America” (2006, Bulletin of the Seismological Society of America, Volume 96, No. 6, pages 2181-2205) as utilized by the National Seismic Hazard Mapping Project (NSHMP) for the 2008 central and eastern US model.
The class replicates the algorithm as coded in
subroutine getAB06
inhazgridXnga2.f
Fortran code available at: http://earthquake.usgs.gov/hazards/products/conterminous/2008/software/The class implement the equation for static stress drop equal to 140 bar.
The class assumes rupture magnitude to be in Mblg scale (given that MFDs for central and eastern US are given in this scale). Therefore Mblg is converted to Mw by using Atkinson and Boore 1987 conversion equation.
Mean value is clipped at 1.5 g for PGA and 3.0 g for SA with periods in range (0.02, 0.55) s.

CoeffsTable
(**kwargs)[source]¶ Bases:
object
Instances of
CoeffsTable
encapsulate tables of coefficients corresponding to different IMTs.Tables are defined in a space-separated tabular form in a simple string literal (heading and trailing whitespace does not matter). The first column in the table must be named “IMT” (or “imt”) and thus should represent IMTs:
>>> CoeffsTable(table='''imf z ... pga 1''') Traceback (most recent call last): ... ValueError: first column in a table must be IMT
Names of other columns are used as coefficients dicts keys. The values in the first column should correspond to real intensity measure types, see
openquake.hazardlib.imt
:>>> CoeffsTable(table='''imt z ... pgx 2''') Traceback (most recent call last): ... ValueError: unknown IMT 'PGX'
Note that
CoeffsTable
only accepts keyword argumets:>>> CoeffsTable() Traceback (most recent call last): ... TypeError: CoeffsTable requires "table" kwarg >>> CoeffsTable(table='', foo=1) Traceback (most recent call last): ... TypeError: CoeffsTable got unexpected kwargs: {'foo': 1}
If there are
SA
IMTs in the table, they are not referenced by name, because they require parametrization:>>> CoeffsTable(table='''imt x ... sa 15''') Traceback (most recent call last): ... ValueError: specify period as float value to declare SA IMT >>> CoeffsTable(table='''imt x ... 0.1 20''') Traceback (most recent call last): ... TypeError: attribute "sa_damping" is required for tables defining SA
So proper table defining SA looks like this:
>>> ct = CoeffsTable(sa_damping=5, table=''' ... imt a b c d ... pga 1 2.4 -5 0.01 ... pgd 7.6 12 0 44.1 ... 0.1 10 20 30 40 ... 1.0 1 2 3 4 ... 10 2 4 6 8 ... ''')
Table objects could be indexed by IMT objects (this returns a dictionary of coefficients):
>>> from openquake.hazardlib import imt >>> ct[imt.PGA()] == dict(a=1, b=2.4, c=-5, d=0.01) True >>> ct[imt.PGD()] == dict(a=7.6, b=12, c=0, d=44.1) True >>> ct[imt.SA(damping=5, period=0.1)] == dict(a=10, b=20, c=30, d=40) True >>> ct[imt.PGV()] Traceback (most recent call last): ... KeyError: PGV() >>> ct[imt.SA(1.0, 4)] Traceback (most recent call last): ... KeyError: SA(period=1.0, damping=4)
Table of coefficients for spectral acceleration could be indexed by instances of
openquake.hazardlib.imt.SA
with period value that is not specified in the table. The coefficients then get interpolated between the ones for closest higher and closest lower period. That scaling of coefficients works in a logarithmic scale of periods and only within the same damping:>>> '%.5f' % ct[imt.SA(period=0.2, damping=5)]['a'] '7.29073' >>> '%.5f' % ct[imt.SA(period=0.9, damping=5)]['c'] '4.23545' >>> '%.5f' % ct[imt.SA(period=5, damping=5)]['c'] '5.09691' >>> ct[imt.SA(period=0.9, damping=15)] Traceback (most recent call last): ... KeyError: SA(period=0.9, damping=15)
Extrapolation is not possible:
>>> ct[imt.SA(period=0.01, damping=5)] Traceback (most recent call last): ... KeyError: SA(period=0.01, damping=5)

Base class for all the ground shaking intensity models.
A Ground Shaking Intensity Model (GSIM) defines a set of equations for computing mean and standard deviation of a Normal distribution representing the variability of an intensity measure (or of its logarithm) at a site given an earthquake rupture.
This class is not intended to be subclassed directly, instead the actual GSIMs should subclass either
GMPE
orIPE
.Subclasses of both must implement
get_mean_and_stddevs()
and all the class attributes with names starting fromDEFINED_FOR
andREQUIRES

- Closest distance to rupture surface. See
get_min_distance()
. rjb
- Distance to rupture’s surface projection. See
get_joyner_boore_distance()
. rx
- Perpendicular distance to rupture top edge projection.
See

. ry0
- Horizontal distance off the end of the rupture measured parallel to
See

. rcdpp
- Direct point parameter for directivity effect centered on the site- and earthquake-specific
See
get_dppvalue()
.
All the distances are available from the
DistancesContext
object attributes with same names. Values are in kilometers.
-
REQUIRES_RUPTURE_PARAMETERS
¶ Set of rupture parameters (excluding distance information) required by GSIM. Supported parameters are:
mag
- Magnitude of the rupture.
dip
- Rupture’s surface dip angle in decimal degrees.
rake
- Angle describing the slip propagation on the rupture surface,
in decimal degrees. See
nodalplane
for more detailed description of dip and rake. ztor
- Depth of rupture’s top edge in km. See
get_top_edge_depth()
.
These parameters are available from the
RuptureContext
object attributes with same names.
-
REQUIRES_SITES_PARAMETERS
¶ Set of site parameters names this GSIM needs. The set should include strings that match names of the attributes of a
site
object. Those attributes are then available in theSitesContext
object with the same names.
-
disaggregate_poe
(sctx, rctx, dctx, imt, iml, truncation_level, n_epsilons)[source]¶ Disaggregate (separate) PoE of
iml
in different contributions each coming fromn_epsilons
distribution bins.If
truncation_level = 3
,n_epsilons = 3
, bin edges are-3 .. -1
,-1 .. +1
and+1 .. +3
.Parameters: n_epsilons – Integer number of bins to split truncated Gaussian distribution to. Other parameters are the same as for
get_poes()
, with differences thatiml
is only one single intensity level andtruncation_level
is required to be positive.Returns: Contribution to probability of exceedance of iml
coming from different sigma bands in a form of 1d numpy array withn_epsilons
floats between 0 and 1.
-
get_mean_and_stddevs
(sites, rup, dists, imt, stddev_types)[source]¶ Calculate and return mean value of intensity distribution and it’s standard deviation.
Method must be implemented by subclasses.
Parameters: - sites – Instance of
SitesContext
with parameters of sites collection assigned to respective values as numpy arrays. Only those attributes that are listed in class’REQUIRES_SITES_PARAMETERS
set are available. - rup – Instance of
RuptureContext
with parameters of a rupture assigned to respective values. Only those attributes that are listed in class’REQUIRES_RUPTURE_PARAMETERS
set are available. - dists – Instance of
DistancesContext
with values of distance measures between the rupture and each site of the collection assigned to respective values as numpy arrays. Only those attributes that are listed in class’REQUIRES_DISTANCES
set are available. - imt – An instance (not a class) of intensity measure type.
See
openquake.hazardlib.imt
. - stddev_types – List of standard deviation types, constants from
openquake.hazardlib.const.StdDev
. Method result value should include standard deviation values for each of types in this list.
Returns: Method should return a tuple of two items. First item should be a numpy array of floats – mean values of respective component of a chosen intensity measure type, and the second should be a list of numpy arrays of standard deviation values for the same single component of the same single intensity measure type, one array for each type in
stddev_types
parameter, preserving the order.Combining interface to mean and standard deviation values in a single method allows to avoid redoing the same intermediate calculations if there are some shared between stddev and mean formulae without resorting to keeping any sort of internal state (and effectively making GSIM not reenterable).
However it is advised to split calculation of mean and stddev values and make
get_mean_and_stddevs()
just combine both (and possibly compute interim steps).- sites – Instance of
-
get_poes
(sctx, rctx, dctx, imt, imls, truncation_level)[source]¶ Calculate and return probabilities of exceedance (PoEs) of one or more intensity measure levels (IMLs) of one intensity measure type (IMT) for one or more pairs “site – rupture”.
Parameters: - sctx – An instance of
SitesContext
with sites information to calculate PoEs on. - rctx – An instance of
RuptureContext
with a single rupture information. - dctx –
An instance of
DistancesContext
with information about the distances between sites and a rupture.All three contexts (
sctx
,rctx
anddctx
) must conform to each other. The easiest way to get them is to call ContextMaker.make_contexts. - imt – An intensity measure type object (that is, an instance of one
of classes from
openquake.hazardlib.imt
). - imls – List of interested intensity measure levels (of type
imt
). - truncation_level –
Can be
None
, which means that the distribution of intensity is treated as Gaussian distribution with possible values ranging from minus infinity to plus infinity.When set to zero, the mean intensity is treated as an exact value (standard deviation is not even computed for that case) and resulting array contains 0 in places where IMT is strictly lower than the mean value of intensity and 1.0 where IMT is equal or greater.
When truncation level is positive number, the intensity distribution is processed as symmetric truncated Gaussian with range borders being
mean - truncation_level * stddev
andmean + truncation_level * stddev
. That is, the truncation level expresses how far the range borders are from the mean value and is defined in units of sigmas. The resulting PoEs for that mode are values of complementary cumulative distribution function of that truncated Gaussian applied to IMLs.
Returns: A dictionary of the same structure as parameter
imts
(see above). Instead of lists of IMLs values of the dictionaries have 2d numpy arrays of corresponding PoEs, first dimension represents sites and the second represents IMLs.Raises: ValueError – If truncation level is not
None
and neither non-negative float number, and ifimts
dictionary contain wrong or unsupported IMTs (seeDEFINED_FOR_INTENSITY_MEASURE_TYPES
).- sctx – An instance of
-
to_distribution_values
(values)[source]¶ Convert a list or array of values in units of IMT to a numpy array of values of intensity measure distribution (like taking the natural logarithm for
GMPE
).This method is implemented by both
GMPE
andIPE
so there is no need to override it in actual GSIM implementations.
-
to_imt_unit_values
(values)[source]¶ Convert a list or array of values of intensity measure distribution (like ones returned from
get_mean_and_stddevs()
) to values in units of IMT. This is the opposite operation toto_distribution_values()
.This method is implemented by both
GMPE
andIPE

openquake.hazardlib.gsim.base.GMPE
Implements the GMPE for induced seismicity in Geothermal Areas derived from stochastic simulations of ground motion constructed by:
- Douglas, J., Edwards, B., Convertito, V., Sharma, N., Tramelli, A.,
- Kraaijpoel, D., Cabrera, B. M., Maercklin, N., and Troise, C. (2013) “Predicting Ground Motion for Induced Earthquakes in Geothermal Areas” Bulleting of the Seismological Society of America, 103(3), 1875 - 1897
The stochastic model by Douglas et al. (2013) provides coefficients for 36 GMPEs, corresponding to different values of Stress Drop (1 bar, 10 bar, 100 bar), Attentuation Quality Factor Q (200, 600, 1800) and high-frequency Kappa (0.005, 0.02, 0.04, 0.05 s).
The present model is implemented for Stress Drop 1 bar, Q 200 and Kappa 0.005 s.
The models for each combination of Stress Drop, Q and Kappa are implemented in subclasses, with only the median coefficients modified in each subclass
Notes on implementation:
- Aleatory uncertainty terms are not supplied for the stochastic coefficients. Instead the adjusted aleatory uncertainty coefficients derived from empirical observations are applied to the stochastic model.
- In the initial coefficient set for the stochastic model coefficients for spectral accelerations up to 10 s are provided. However, the empirical aleatory uncertainties are provided only for periods up to 0.5012 s. Therefore, after consulation with J. Douglas, it is decided to limit longest applicable spectral period to Sa (0.5 s), rather than extrapolate the empricial aleatory coefficients to longer periods.
- For PGA and Sa (< 0.01 s) the aleatory uncertainty coefficients for Sa (0.01 s) are applied (J. Douglas, pers. comm.)
- For Sa (< 0.01 s) the coefficients are interpolated assuming PGA occurs at Sa (0.005 s) (J. Dougla, pers. comm.). We therefore limit the short period range to 0.005 s

N.B. In the paper, and with confirmation from the author, the aleatory variability terms from the empirical model are used in conjunction with the median coefficients from the stochastic model. In the empirical model, coefficients for a single-station intra-event sigma are derived. These are labeled as “phi”. Inter-event coefficients corresponding to two observed geothermal sequences (Soultz-Sous-Forets and Basel) are also derived. The inter-event standard deviation is therefore taken as the ordinary mean of the two inter-event sigma terms

Implements GMPE developed by Ezio Faccioli, Aldo Bianchini and Manuela Villani and published as “New ground motion prediction equations for T>1 s and their influence on seismic hazard assessment” (Proceedings of the University of Tokyo Symposium on Long-Period Ground Motion and Urban Disaster Mitigation, March 17-18, 2010). This class implements the prediction equations for horizontal peak ground acceleration, and 5%-damped spectral acceleration - equation 2 page 2, plus site and faulting style terms (equations 3 and 5, page 3). Spectral acceleration (SA) values are obtained from displacement response spectrum (DSR) values (as provided by the original equations) using the following formula
SA = DSR * (2 * π / T) ** 2
This class extends :class: ~openquake.hazardlib.gsim.cauzzi_faccioli_2008.CauzziFaccioli2008 because the functional form is almost identical - the only difference is in the third term which rather then using hypocentral distance, uses closest distance to the rupture and additionaly considers a magnitude dependence.

openquake.hazardlib.gsim.base.GMPE
Implements GMPE developed by Arthur Frankel et al. and documented in “National Seismic-Hazard Maps: Documentation June 1996” (USGS - Open File Report 96-532) available at: http://earthquake.usgs.gov/hazards/products/conterminous/1996/documentation/ofr96-532.pdf
The GMPE is used by the National Seismic Hazard Mapping Project (NSHMP) for the 2008 central and eastern US hazard model.
This class replicates the algorithm as implemented in
subroutine getFEA
in thehazgridXnga2.f
Fortran code available at: http://earthquake.usgs.gov/hazards/products/conterminous/2008/software/The GMPE is defined by a set of lookup tables (see Appendix A) defined from minimum magnitude Mw=4.4 to maximum magnitude Mw=8.2, and from (hypocentral) distance 10 km to 1000 km. Values outside these range are clipped.
Lookup tables are defined for PGA, and SA at the following periods: 0.1, 0.2, 0.3, 0.5, 1.0, 2.0. The GMPE does not allow for interpolation on unsupported periods.
The class assumes rupture magnitude to be in Mblg scale (given that MFDs for central and eastern US are given in this scale). However lookup tables are defined for Mw. Therefore Mblg is converted to Mw by using Atkinson and Boore 1987 conversion equation.
Coefficients are given for the B/C site conditions.

In a GMPE tables the expected ground motions for each of the IMTs over the range of magnitudes and distances are stored in an hdf5 file on the path specified by the user.
In this version of the GMPE the expected values are interpolated to the required IMT, magnitude and distance in three stages.
- Initially the correct IMT values are identified, interpolating in log-T|log-IML space between neighbouring spectral periods.
- The IML values are then interpolated to the correct magnitude using linear-M|log-IML space
- The IML values are then interpolated to the correct distance via linear-D|linear-IML interpolation

Gupta2010SSlab
[source]¶ Bases:
openquake.hazardlib.gsim.atkinson_boore_2003.AtkinsonBoore2003SSlab
Implements GMPE of Gupta (2010) for Indo-Burmese intraslab subduction.
This model is closely related to the model of Atkinson & Boore (2003). In particular the functional form and coefficients
C2
-C7
of Gupta (2010) are adopted from Atkinson & Boore (2003). The only substantive changes are a) the horizontal component modeled is different (as noted below) b) a coefficientC8
and a dummy variablev
are added to model vertical motion and c) the coefficientC1
is recalculated based on a database of “a total of 56 three-component accelerograms at 37 different sites from three in-slab earthquakes along the Indo-Burmese subduction zone” (p 370).Equation (2) p. 373 gives the form of the equation which was fitted:
log Y - C2*M - C3*h - C4*R + g log R = C1 + C8*v + sigma
The left-hand side of this equation was computed using event parameters and the coefficients of Atkinson & Boore (2003). The regression coefficients C1 and C8 on the right-hand side were slightly smoothed after fitting. Note that since “v=0 for horizontal and 1 for vertical motion”, and since the current implementation only models horizontal motion, we can subclass directly from
openquake.hazardlib.gsim.atkinson_boore_2003.AtkinsonBoore2003SSlab
, modifying only the metadata constants and regression coefficients.Page number citations in this documentation refer to Gupta (2010).

Equation (5) on p. 881 predicts ground motion for shallow events (depth <= 30 km):
log(pre) = a*M + b*X - log(X + d*10^(e*M)) + c + epsilon
“where pre is the predicted PGA (cm/sec^2), PGV (cm/sec), or 5% damped response spectral acceleration (cm/sec^2)” (p. 883) and a, b, c and d are tabulated regression coefficients. Note that subscripts on the regression coeffients have been dropped - subscript 1 denoted “shallow” while subscript 2 denoted “deep” - so that the “deep” model of equation (6) can be implemented trivally by changing coefficients and setting d = 0.
Equation (8) on p. 883 gives the model used for site amplitfication:
G = p*log(VS30) + q
Where p and q are tabulated regression coefficients.
Equation (9) on p. 884 for the ground motion at a given site:
log(pre_G) = log(pre) + G
No adjustment of epsilon is made as a function of VS30.
Note finally that “log represents log_10 in the present study” (p. 880).

This class implements the GMPE for Active Shallow Crust earthquakes (Asc suffix).
The GMPE distinguishes between rock (vs30 >= 760) and stiff soil (360 <= vs30 < 760) and soft soil (vs < 360) which equates to the New Zealand site class A and B (rock) and C,D and E (soil). The rake angle is also taken into account to distinguish between faulting mechanisms. A hanging-wall term is noted in the functional form of the model in the paper but is not used at present. Furthermore, a Rvolc (volcanic path distance) is noted in the functional form but this is not implemented in the McVerry2006Asc model, it is implemented in a seperate GMPE McVerry2006Volc where Rvol=Rrup as this is how it is implemented in the NZ Seismic Hazard Model (Stirling 2012)

non_verified
= True¶ Verification of mean value data was done by digitizing Figures 3 and 5 using http://arohatgi.info/WebPlotDigitizer/ app/. Maximum error was relatively high, approximately 10%, but could be reduced to approximately 1.5% by making the following changes to what may be typographical errors in the published coefficients. In each case the value sugstituted is interpolated from neighbouring values.

Rietbrock, A., Strasser, F., Edwards, B. (2013) A Stochastic Earthquake Ground-Motion Prediction Model for the United Kingdom. Bulletin of the Seismological Society of America, 103(1), 57 -77
The GMPE is derived for the United Kingdom, a low seismicity region. Consequently ground motions are generated via numerical simulations using a stochastic point-source model, calibrated with parameters derived from local weak-motion data. This implementation applies to the case when stress drop is considered to be self-similar (i.e. independent of magnitude).

[source]¶ Bases:
openquake.hazardlib.gsim.base.GMPE
Implements GMPE of Sharma et al. (2009). This GMPE is intended for the Indian Himalayas but is based on data from both Zagros in Iran and the Himalayas. The combination of these two regions is motivated by the sparsity of near field data. Seismotectonic similarity is supposed based on both regions being continental collision zones, and in spite of the lack of subduction in Zagros.
Note that Figure 7-9 of Sharma et al. (2009) are in error (Sharma, personal communication). This implementation is verified against test vector obtained from lead author.
Support for PGA has been added by assuming it to be equal to the spectral acceleration at 0.04 s. This is assumed by the authors in the captions for Figures 11-13 anyway.
