class openquake.hazardlib.gsim.megawati_pan_2010.MegawatiPan2010

Implements GMPE developed by Kusnowidjaja Megawati and Tso-Chien Pan and published as “Ground-motion attenuation relationship for the Sumatran megathrust earthquakes” (2010, Earthquake Engineering & Structural Dynamics Volume 39, Issue 8, pages 827-845).

COEFFS = <openquake.hazardlib.gsim.base.CoeffsTable object>

Coefficient table for rock sites, see table 3 page 227.

DEFINED_FOR_INTENSITY_MEASURE_COMPONENT = 'Average horizontal'

Supported intensity measure component is geometric mean of two horizontal components,

DEFINED_FOR_INTENSITY_MEASURE_TYPES = set([<class 'openquake.hazardlib.imt.PGA'>, <class 'openquake.hazardlib.imt.SA'>, <class 'openquake.hazardlib.imt.PGV'>])

Supported intensity measure types are spectral acceleration, peak ground velocity and peak ground acceleration, see table IV pag. 837

DEFINED_FOR_STANDARD_DEVIATION_TYPES = set(['Total'])

Supported standard deviation types is total, see equation IV page 837.

DEFINED_FOR_TECTONIC_REGION_TYPE = 'Subduction Interface'

Supported tectonic region type is subduction interface along the Sumatra subduction zone.

REQUIRES_DISTANCES = set(['rhypo'])

Required distance measure is hypocentral distance, see equation 1 page 834.

REQUIRES_RUPTURE_PARAMETERS = set(['mag'])

Required rupture parameters are magnitude, and focal depth, see equation 10 page 226.

REQUIRES_SITES_PARAMETERS = set([])

Required site parameter is only Vs30 (used to distinguish rock and deep soil). This GMPE is for very hard rock site condition, see the abstract page 827.
