Magnitude 7.6 quake near El Salvador

Last updated: 2018-03-26 17:50:59 UTC

The Anza group at the University of California San Diego operates a broadband seismograph network consisting of 16 (+ 2) three component broadband seismograph stations centered near Anza California (see map). We are also partners in a 10 station broadband network, KNET, that spans the Kazakstan/Kyrgyzstan border in Central Asia.

At approximateley 09:33 PST a large (7.6) earthquake occurred off the coast of Central America. The Associated Press has reported damage to buildings and some casualties.

The epicentral distance (distance separating the epicenter and the recording network) for KNET is ~122.5 degrees (13621 km). For ANZA the distance is ~32.6 degrees (3625 km). This quake is considered to be a "teleseismic" event based on the epicentral distance.

This map shows the mainshock (red circle). Anza network stations are dark blue triangles. KNET network stations are pink triangles. Background seismicity is plotted in light dots with warmer colors representing deep earthquakes.
