** NOTICE ** On July 11, 2018 the SCEDC FDSN dataselect web service will return HTTP 400 for requests from Swarm. Requests from the Swarm application have begun to impact the overall performance of our web services for all users and the services were not designed for the real-time monitoring goals of this application. To ensure the best service performance for all users, the SCEDC will not be servicing requests by Swarm applications. For real-time feeds to CI stations, we encourage Swarm users to use the IRIS SEEDLink service. 60 CI stations are sent to IRIS in real-time. 07/11/2018

 

New waveform relocated earthquake and focal mechanism catalogs available 06/12/2018

New focal mechanism catalogs for 2015-2016 now available 01/04/2017

 

2016

Improved polygon search now available on SCEDC catalog search pages. 12/13/2016

 

** NOTICE ** On October 19, 2016 the SCEDC will be transitioning to its new archival system. We expect web services and STP to be offline from 10am-12pm PDT. Please report any issues to scedc@gps.caltech.edu if you see any issues accessing SCEDC archives.

 

** NOTICE ** On July 1, 2015, a bug was introduced into STP that caused triggered data to become leap-second noncompliant. Continuous data requests were not affected. The bugfix has been deployed on June 22, 2016. We recommend users re-download data if your data set contains events between July 1, 2015 and June 22, 2016 AND you made the download with the TRIG command between these dates 06/23/2016

New waveform relocated earthquake and focal mechanism catalogs available (01/05/2016)

 

SCSN has started calculating an additional magnitude type, a revised local Magnitude (Mlr), for events larger than 3.5. (01/12/2016)

 

2015

On January 12, 2015, the SCEDC website will be moving to a new address, http://scedc.caltech.edu. Our web services, PHP, and catalog search pages will move to the address http://service.scedc.caltech.edu. The old address, http://scedc.caltech.edu, will remain online and direct traffic to the new addresses at least until April 12, 2015.

On September 22, 2015, the SCEDC earthquake catalogs will report event depths relative to the WGS84 reference ellipsoid. Older versions of the catalog with the model depth datum will be available on the SCEDC repository on GitHub. Other changes in processing that affect the earthquake catalogs are documented here.

** Notice - August 22, 2014 ** On July 7, 2014, a bug was introduced into STP that caused continuous data to become leap-second noncompliant. The bugfix has been deployed on this STP server on August 22, 2014. It is recommended that you re-download continuous data downloaded between July 7, 2014, and August 22, 2014.

 

2013

The SCEDC now has a new version of web STP in beta testing.
Web STP allows user to retrieve continuous or triggered waveform data, as well as download phase data in STP format for events in the SCEDC earthquake catalog. Users can either use the form or call the service programmatically via curl or wget.

2012

Version 1.6.2 of the STP command-line client is available as of March 6, 2012. This version corrects a bug that caused a segmentation fault on 64-bit machines when the main STP server was overloaded.

 

GPS data, waveform scans, and STP will be offline for about 10 minutes starting at 3pm today. (April 4, 2012)

 

SCEDC is now archiving real time GPS displacement waveforms. (July 2, 2012)

 

We apologize for the SCEDC website outage. We are working on getting the site back online. Please let us know if you notice anything that is not working. (07/17/2012)
