The Earthquake Data Portal API provides event information in both SOAP and REST-style services. For SOAP, the information is provided in QuakeML format. For REST, information is in either QuakeML or JSON formats. Users can do Event Searches, review Latest Events and look at Event Details. Data on seismic waveforms and their velocity are also provided, including the ability to predict arrival times and locations after they have been detected. The API will identify the data providers within the Seismolink network.
