Note: You can leave fields blank that do not apply to your search.

Circle	Return stations within a given distance (in kilometers) of a location
Circle	Return events within a given distance (in kilometers) of a location
Coordinates	Return stations within a range of latitudes or longitudes
Coordinates	Return events within a range of latitudes or longitudes
Country/State	Return events in a given country or U.S. state
Date/Time	Search by date and time (in UTC) in yyyy-mm-dd hh:mm:ss format
Earthquake Name	May contain the nearby city to the epicenter. A search for a nearby city returns events whose earthquake name contains the name of the nearby city.
Epicentral Dist. (km)	Specify an epicentral distance range (min to max inclusive) to narrow down search criteria
Event IDs	Search event(s) by ID(s), e.g. CI37904927,CI38043999. Most other options are unavailable when an event ID is specified.
Fault Type	Return events with specific fault type. Multiple fault types may be selected for the search. Leaving them unselected will search for all possible types.
Group By	Specify the grouping of the metadata. Default is grouping by stations. Grouping by stations will group records under the same station into a single data structure.
Include Inactive Stations	Check to include inactive stations in search criteria, uncheck otherwise.
Login Email	Available if dataset is selected as the return type. Registered e-mail must be provided in order to download data files.
Metadata Format	Specify output format. Default is JSON. Available if metadata is selected as the return type.
Magnitude	Self-explanatory. Returns events within a range of magnitudes. Default returns all magnitude ranges
Network	Two letter Network ID of station (multiple network IDs can be listed, e.g. CE,AA)
Order Records By	Specifies the sort order of the record output. Default is by epicentral distance (descending).
PGA (g)	Specify a PGA range (min to max inclusive) to narrow down search criteria
Processed, Raw, Plot	Available if dataset is selected as the return type. Checking processed and raw will package both processed and raw data in the returned (.ZIP) file.
Return Type	Return type of the output. Dataset will return a (.ZIP) file packaged with the requested data. Metadata will return either (.JSON) or (.XML), depending on user selection.
Station Code(s)	Search station(s) by code(s), e.g. CE24319,AAAK16. Most other options are unavailable when a station code is specified.
Station Name	Name of station, accepts wildcards
Station Type	Default is Any, alternative options are Array, Ground, Building, Bridge, Dam, Tunnel, Wharf, Other
