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.

In the SRC file, lines starting with "#" are considered comments and are ignored by the Platform. 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) ====

Finally, the CORNER_FREQ parameter is only used by the UCSB method. This parameters specifies the frequency at which the Fourier Amplitude Spectrum (FAS) of the moment rate spectrum decays at a rate of ~ -2 from the flat part of the spectrum, in log log domain. There is a relationship between the corner frequency and the average stress drop, e.g. (Brune 1970 and 1971). For specific regions, the stress drop is a parameter and can be measured from regional seismicity. In practice, look at the regional seismicity, calculate stress drops. From these calculations one can choose the appropriate stress drop and compute the corner frequency from the actual moment, rupture area and chosen stress drop.

Each line in the station list (STL) file contains information about one station used in the simulation. Lines starting with "#" are comments and are ignored by the Broadband Platform. Each line should contain at least 3 parameters, but can also include 4 or 6 parameters. The first 3 parameters (required) are longitude, latitude, and station name. Latitude and longitude should be provided in decimal degrees (for example, the latitude of 37 degrees, 30 minutes, and 0 seconds should be specified as 37.5). The station name is an identifier for the station and should contain between 3 and 10 characters. These 3 parameters are the minimum set required for each of the stations. Optionally, a station can include a 4th parameter, the Vs30 (in meters per second) for the particular location where the station is located. Also, optionally, each station can include 2 more parameters that specify the frequency range (in Hertz) where recordings for a specific station are valid. These 2 values, used only when the platform runs in validation mode, are used to filter data out of the Goodness of Fit (GoF) plots. Please note that it is not possible to include the frequency ranges without including the Vs30 parameter. If the frequency range is not specified, the Broadband Platform will not exclude any data from the GoF plot.

Each line should contain at least 3 parameters, but can also optionally include a total of 4 or 6 parameters. The first 3 parameters (required) are longitude, latitude, and station name. Latitude and longitude should be provided in decimal degrees (if converting from degrees, minutes, and seconds, the latitude of 37 degrees, 30 minutes, and 0 seconds should be specified as 37.5). The station name is an identifier for the station and should contain between 3 and 10 characters. These 3 parameters form the minimum set required for each of the stations. Optionally, a station can include a 4th parameter, the Vs30 (specified in meters per second) for the particular location where the station is located. Also optionally, each station can include 2 more parameters that specify the frequency range (in Hertz) where recordings for a specific station are valid. These 2 values, used only when the platform runs in validation mode, are used to filter untrusted data out of the Goodness of Fit (GoF) plots. Please note that it is not possible to include the frequency ranges without including the Vs30 parameter. If the frequency range is not specified, the Broadband Platform will use the entire 0.1Hz to 100Hz range for the GoF plots.

In the BBP file, lines beginning with a '%' or '#' are considered comments and should be ignored. The comment section at the top of the file contains useful information about the BBP file. For example, it includes the station name corresponding to the data, as well as the number of points in the file and the DT used in the simulation.
 +
 +
The rest of the file is organized in 4 columns containing the actual time series data. As indicated in the file's header, the first column corresponds to the timestamp (in seconds), and the last 3 columns correspond to the 3 components - 2 horizontals (north/south and east/west), and 1 vertical (up/down). For a velocity time history, the units indicated at the top of the file will be cm/s and for an acceleration time history, they will be cm/s/s. Each line in the file corresponds to a data point, spaced DT seconds apart from the next point.

==== Velocity Model File ====
  
 +
In the Broadband Platform, 1D velocity model files are part of a velocity model package in the Platform, and are generally tied to a region. All Broadband Platform simulations using that specific region will share the same velocity model file.
 +
 +
In the velocity model file, the first line indicates how many layers compose the velocity model. The following lines, one for each layer, describes the layer in details. The first column is the thickness of the layer (in kilometers). The second and third columns are Vp and Vs, respectively, both in km/s. The forth column contains the rho value (in g/cm3), while the last two columns contain the Qp and Qs parameters respectively.

==== Broadband Platform Workflow Description (XML File) ====
+
The Broadband Platform uses a XML file to describe the workflow, or processing sequence, required to produce all simulation results. In the workflow description, the <BBP_Modules> section includes a list of all modules that need to run, in the required sequence, with the necessary parameters. For each module, the file contains a <BBP_Module> element, that names the module, includes the files needed to be copied to the indata directory before the module is executed, and the arguments needed for the module to produce the required results. File paths can be absolute paths, or can be referenced to one of Broadband's environmental variables. For example, "BBP_INSTALL_VAL" and "BBP_INSTALL_GF" will refer to the base directories where validation packages and velocity model packages are installed. A workflow description file is produced automatically by the Platform as the user walks through the interactive prompt. It is written to the xml directory before the simulation starts.

This page describes the format for the files used in Broadband Platform Simulations. The simple source description (SRC) and the station list (STL) files are inputs to 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. Time history (BBP) files are produced by the Platform for each station included in the station list. 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 is used to replace the interactive prompts of the Platform.

SImple Source Description (SRC) file

Below is a sample SRC file, used to describe the 1989 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

In the SRC file, lines starting with '#' are considered comments and are ignored by the Platform. 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, where model-specific parameters are located, 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 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.

Finally, the CORNER_FREQ parameter is only used by the UCSB method. This parameters specifies the frequency at which the Fourier Amplitude Spectrum (FAS) of the moment rate spectrum decays at a rate of ~ -2 from the flat part of the spectrum, in log log domain. There is a relationship between the corner frequency and the average stress drop, e.g. (Brune 1970 and 1971). For specific regions, the stress drop is a parameter and can be measured from regional seismicity. In practice, look at the regional seismicity, calculate stress drops. From these calculations one can choose the appropriate stress drop and compute the corner frequency from the actual moment, rupture area and chosen stress drop.

Each line in the station list (STL) file contains information about one station used in the simulation. Lines starting with '#' are comments and are ignored by the Broadband Platform. Each line should contain at least 3 parameters, but can also optionally include a total of 4 or 6 parameters. The first 3 parameters (required) are longitude, latitude, and station name. Latitude and longitude should be provided in decimal degrees (if converting from degrees, minutes, and seconds, the latitude of 37 degrees, 30 minutes, and 0 seconds should be specified as 37.5). The station name is an identifier for the station and should contain between 3 and 10 characters. These 3 parameters form the minimum set required for each of the stations. Optionally, a station can include a 4th parameter, the Vs30 (specified in meters per second) for the particular location where the station is located. Also optionally, each station can include 2 more parameters that specify the frequency range (in Hertz) where recordings for a specific station are valid. These 2 values, used only when the platform runs in validation mode, are used to filter untrusted data out of the Goodness of Fit (GoF) plots. Please note that it is not possible to include the frequency ranges without including the Vs30 parameter. If the frequency range is not specified, the Broadband Platform will use the entire 0.1Hz to 100Hz range for the GoF plots.

In the BBP file, lines beginning with a '%' or '#' are considered comments and should be ignored. The comment section at the top of the file contains useful information about the BBP file. For example, it includes the station name corresponding to the data, as well as the number of points in the file and the DT used in the simulation.

The rest of the file is organized in 4 columns containing the actual time series data. As indicated in the file's header, the first column corresponds to the timestamp (in seconds), and the last 3 columns correspond to the 3 components - 2 horizontals (north/south and east/west), and 1 vertical (up/down). For a velocity time history, the units indicated at the top of the file will be cm/s and for an acceleration time history, they will be cm/s/s. Each line in the file corresponds to a data point, spaced DT seconds apart from the next point.

Velocity Model File

In the Broadband Platform, 1D velocity model files are part of a velocity model package in the Platform, and are generally tied to a region. All Broadband Platform simulations using that specific region will share the same velocity model file.

In the velocity model file, the first line indicates how many layers compose the velocity model. The following lines, one for each layer, describes the layer in details. The first column is the thickness of the layer (in kilometers). The second and third columns are Vp and Vs, respectively, both in km/s. The forth column contains the rho value (in g/cm3), while the last two columns contain the Qp and Qs parameters respectively.

Currently available 1D velocity models are:

Broadband Platform Workflow Description (XML) File

The Broadband Platform uses a XML file to describe the workflow, or processing sequence, required to produce all simulation results. In the workflow description, the <BBP_Modules> section includes a list of all modules that need to run, in the required sequence, with the necessary parameters. For each module, the file contains a <BBP_Module> element, that names the module, includes the files needed to be copied to the indata directory before the module is executed, and the arguments needed for the module to produce the required results. File paths can be absolute paths, or can be referenced to one of Broadband's environmental variables. For example, "BBP_INSTALL_VAL" and "BBP_INSTALL_GF" will refer to the base directories where validation packages and velocity model packages are installed. A workflow description file is produced automatically by the Platform as the user walks through the interactive prompt. It is written to the xml directory before the simulation starts.
