last updated: 05/11/09 08:48.43 (PDT)
On Saturday May 9 2009 at 6:16 PM (PDT) the USArray seismic network recorded an earthquake (preliminary Mw 6.1) located off the coast of Ecuador.
Initial source parameters for this tremor are indicated below. The epicentral distance (i.e. distance separating the epicenter and the closest station in the recording network, TIGA) for the USArray is 3329 km (29.91 degrees).
If you felt the quake, the USGS would like to know. Please add your comments to the USGS page "Did you feel it?".
