Usage
| Model parameters | |
|---|---|
| Model | Specify the model. List of models |
| Green's Functions | Request raw Green’s functions with a delta (impulse) source. |
| Output parameters | |
| Format | Specify output file to be either miniSEED or a ZIP archive of SAC files. |
| Label | Specify a label to be included in file names and HTTP file name suggestions. |
| Components |
Specify the orientation of the synthetic seismograms as a list of any
combination of Z (vertical), N (north), E (east),
R (radial), T (transverse)
|
| Units | Specify either displacement, velocity or acceleration for the synthetics. |
| Sampling Interval | Specify the sampling interval in seconds. |
| Kernel Width | Specify the width of the sinc kernel used for resampling to requested sample interval, relative to the original sampling rate. |
| Time parameters | |
| Origin Time | Specify the source origin time. This must be specified as an absolute date and time. |
| Start Time |
Specifies the desired start time for the synthetic trace(s). This may be specified as either:
phase[+-]offset it is interpreted as a phase-relative time,
for example P-10 (meaning Pwave arrival time minus 10 seconds). Use of a phase-relative time
requires the specification of an origintime. If the value is a numerical value it is
interpreted as an offset, in seconds, from the origintime.
|
| End Time |
Specifies the end time for the synthetic trace(s). This may be specified as either:
phase[+-]offset it is interpreted as a phase-relative time.
If the value is a positive numerical value it is
interpreted as an offset, in seconds, from the starttime.
|
| Receiver parameters | |
| Latitude | Specify the receiver latitude in degrees. |
| Longitude | Specify the receiver longitude in degrees. |
| Network |
Specify a network code combined with station to identify
receiver coordinates of a operating station.
|
| Station |
Specify a station code combined with network to identify
receiver coordinates of a operating station.
|
| Station Code |
Specify the station code for synthetic. Otherwise the value of station
will be used if provided.
|
| Source parameters | |
| Event ID | Specify an event identifier in the form [catalog]:[eventid]. The origin time, centroid location and moment tensor of the solution will be used as the source. The only catalog currently supported is Global CMT. Search for GCMTs |
| Latitude | Specify the source latitude in degrees. |
| Longitude | Specify the source longitude in degrees. |
| Depth | Specify the source depth in meters. |
| As Moment Tensor |
Specify a source in moment tensor components as a list:
Mrr,Mtt,Mpp,Mrt,Mrp,Mtp with values in Newton meters (Nm).
|
| As Double Couple |
Specify a source as a double couple. The list of values are strike,dip,rake[,M0],
where strike, dip and rake are in degrees and M0 is the scalar seismic moment in Newton meters (Nm).
If not specified, a value of 1e19 will be used as the scalar moment.
|
| As Forces |
Specify a force source as a list of Fr,Ft,Fp in units of Newtons (N).
|
| Nodata | If no data is returned by the service, return
a 404 response rather than the
default 204. Learn more about HTTP response codes. |
