The Nevada Broadcast of Earthquakes

Archive of Non-Response to 7:54 AM PST Explosion East of Sparks

The Nevada Broadcast of Earthquakes is an experimental prototype earthquake warning and response system. NBE is a project of the Nevada Seismic Research Affiliates of the University of Nevada, Reno Foundation.

Please call (702) 784-4975 to verify any event reported here.

Netscape 1.1 will automatically reload this page every minute.

Click on the image for a larger map in GIF format, or here for a map in PostScript format showing the most recent 50 events (about 60 kbytes). Each event is labeled with its date, magnitude, and the number of stations that it triggered (apparent events with magnitudes above 3.0 that triggered less than 10 stations are probably not real earthquakes). The largest and the latest of the last 50 events are also labeled boldly.

The PostScript plot is most usefully sent to your printer to output a high-resolution map. You can view a PostScript plot on your screen using a PostScript display program such as GhostScriptor Adobe Acrobat Distiller and Reader. Unfortunately, this PostScript file is notEPS and will not directly import to popular page-layout or graphics applications.


The probable earthquakes listed appear on this page (near the bottom) within a few minutes of their occurrence.

The UNR Seismological Laboratory hopes to continually increase the reliability of this system. Rapid earthquake locations are also available to the public on display terminals located at the Seismological Lab next to our earthquake helicorder display.

Large earthquakes may also appear within a few minutes on the UNRSL Helicorder Camera.

The information included in these documents is intended to improve earthquake preparedness; however, it does not guarantee the safety of an individual structure or facility. The State of Nevada does not assume liability for any injury, death, or property damage that occurs in connection with an earthquake.

Please call (702) 784-4975 to verify any event reported here.

   Entries may contain ERRORS and may be UPDATED or DELETED at any time.
   Entries have up to a 50% chance of not representing any actual earthquake.
   Entries with origin times within 30 seconds may represent a single event.

   This is a list of the previous 50 automated locations for magnitude 2.0
   or greater events recorded by the UNR Western Great Basin Seismic Network.
   All times are Greenwich Mean Time.  
   Subtract 8 hours for Pacific Standard time, and 7 hours for Pacific
   Daylight time.
   Depths are in km.

   Magnitudes are estimated from coda amplitude decay on high-gain, vertical
   components only.
