openquake.hmtk.seismicity.smoothing.kernels package¶

Submodules¶

Module openquake.hmtk.seismicity.smoothing.kernels.base implements the abstract base class for the smoothing kernels

class openquake.hmtk.seismicity.smoothing.kernels.base.BaseSmoothingKernel[source]¶

Bases: object

Abstract Base Class to smooth a grid according the sets of regular smoothing kernels

abstract smooth_data(data, config)[source]¶

Applies the smoothing Kernel

Parameters

data (numpy.ndarray) – Earthquake grid counts in the form [Longitude, Latitude, Depth, Count] where Longitude, Latitude and Depth correspond to the mid-points of each cell!
config (dict) – Algorithm configuration parameters

class openquake.hmtk.seismicity.smoothing.kernels.isotropic_gaussian.IsotropicGaussian[source]¶

Applies a simple isotropic Gaussian smoothing using an Isotropic Gaussian Kernel - taken from Frankel (1995) approach

smooth_data(data, config, is_3d=False)[source]¶

Applies the smoothing kernel to the data

Parameters

data (np.ndarray) –

Raw earthquake count in the form [Longitude, Latitude, Depth,
Count]
config (dict) – Configuration parameters must contain: * BandWidth: The bandwidth of the kernel (in km) (float) * Length_Limit: Maximum number of standard deviations
