Revision as of 22:38, 30 December 2013

This page describes the format for the files used in Broadband Platform Simulations. The simple source description (SRC file) and the station list (STL file) are inputs to the Broadband Platform simulations, and must be provided for every run. The velocity model file is part of a velocity model configuration package and is also an input to the platform. A single velocity model file can be shared among several simulations using the same region. The time history (BBP) file is produced by the Platform. The Broadband Platform workflow description (XML file) is an intermediate product of the Broadband Platform. It is produced automatically by the Platform, but can also be provided by the user in cases where script automation can be used to replace the interactive prompts of the Platform.

SImple Source Description (SRC file)

Below is a sample SRC file, used to describe the Loma Prieta earthquake in Northern California: 

#
# Loma Prieta source file
#
MAGNITUDE = 6.94
FAULT_LENGTH = 40.0
FAULT_WIDTH = 17.5
DEPTH_TO_TOP = 3.85
STRIKE = 128
RAKE = 145
DIP = 70
LAT_TOP_CENTER = 37.0789
LON_TOP_CENTER = -121.8410
HYPO_ALONG_STK = 0.0
HYPO_DOWN_DIP =  14.75
#
# Model specific parameters
#
DWID = 0.1
DLEN = 0.1
CORNER_FREQ = 0.15
#
# Alternative SEEDS create alternative .srf
#
SEED = 2379646

The first few parameters are used to specify the event magnitude and describe the rupture. FAULT_LENGTH is used to specify the extent of the fault plane in the along strike direction, while FAULT_WIDTH specifies the dimension of the fault plane in the down dip direction. DEPTH_TO_TOP specifies how deep the fault plane is located (zero means a surface rupture). LAT_TOP_CENTER and LON_TOP_CENTER specify the location of the top center point of the fault plane. HYPO_ALONG_STK and HYPO_DOWN_DIP specify the hypocenter location within the fault plane, with the (0, 0) coordinate being the TOP_CENTER of the fault plane. Therefore, HYPO_ALONG_STK goes from -(FAULT_LENGTH / 2) to (FAULT_LENGTH / 2), with zero being the mid-point of the fault plane. HYPO_DOWN_DIP starts at zero (top of the plane) and goes down to FAULT_WIDTH. All distances should be provided in kilometers (km). STRIKE, RAKE, and DIP are used to describe the fault mechanism and should be provided in degrees.

In the second part of the file, DWID and DLEN are used to provide the step interval (again, in kilometers) for the rupture creation. Smaller values will result in increased computation time. The CORNER_FREQ parameter is only used by the UCSB method. Finally, the SEED parameter enables randomization in the code (e.g. it allows different slip distributions to be generated). By using the same SEED parameter, users can generate reproducible results in the Broadband Platform.

Station List (STL file)

Below is a sample STL file, with the stations used in the Loma Prieta earthquake (located in the San Francisco Bay Area):
