The U.S. Geological Survey (USGS) is reporting a 7.0-magnitude earthquake off the coast of central Peru today (September 25, 2013). No Pacific-wide tsunami warning was issued; none is in effect. The Pacific Tsunami Warning Center did warn of possible local events, saying:
NO DESTRUCTIVE WIDESPREAD TSUNAMI THREAT EXISTS BASED ON HISTORICAL EARTHQUAKE AND TSUNAMI DATA.
HOWEVER – EARTHQUAKES OF THIS SIZE SOMETIMES GENERATE LOCAL TSUNAMIS THAT CAN BE DESTRUCTIVE ALONG COASTS LOCATED WITHIN A HUNDRED KILOMETERS OF THE EARTHQUAKE EPICENTER. AUTHORITIES IN THE REGION OF THE EPICENTER SHOULD BE AWARE OF THIS POSSIBILITY AND TAKE APPROPRIATE ACTION.
We are hearing reports that the inhabitants of the Camaná and Castilla areas of the region of Arequipa felt the earthquake — and that hundreds of people went to the streets. There are also reports of landslides that have blocked the Panamerican Highway near the Chaparra bridge. No word yet on injuries or other damages.
