Download By Site Coordinates (JSON)

Get broadband ground motions, response spectra, and metadata for site coordinates (JSON format).

Requested Parameters

Required Parameters:

Latitude

Specify the latitude of the site location. Example: 47.6

Longitude

Specify the longitude of the site location. Example: -122.3

Optional Parameters:

Unprocessed

Specify whether or not the broadbands should be unprocessed. Note that you can not specify Response Spectra calculations with unprocessed broadbands. Example: True or False Default: True

ResponseSpectra

Specify whether or not the spectral accelerations should be calculated and return. Example: True or False Default: False

GetDistanceToRupture

Specify whether or not the closest distance to rupture should be calculated and return. Example: True or False Default: False

SensitivityRuns

Download the sensitivity runs from Wirth et al. 2018 (instead of logic tree runs part of the Frankel et al. 2018 ). Example: True or False Default: False

Output

Web service response: JSON is organized by realization where each record contains the following fields:

Realization

realization id

StationCode

Unique station identifier

DistanceToClosestSite

Closest distance from the specified latitude and longitude to the station latitude and longitude

Timestep

Time step of acceleration history in seconds

CutOffTime

Time where the numerical instability occurs. If motions are processed then the acceleration history does not include content after the cutoff time

AccelerationHistory-EW

Acceleration history in the east-west direction (in units of g)

AccelerationHistory-NS

Acceleration history in the north-south direction (in units of g)

AccelerationHistory-Vert

Acceleration history in the down-up direction (in units of g)

SpetralAcceleration-EW

Spectral accelerations in the east-west direction (in units of g)

SpetralAcceleration-NS

Spectral accelerations in the north-south direction (in units of g)

Period

Periods of spectral accelerations (in seconds)

ClosestDistanceToRupture

Closest distance to fault rupture plane (in km)
