The following is a press release by the United States Geological Survey, National Earthquake Information Center:
A major earthquake occurred NEAR THE COAST OF SOUTHERN PERU, about 120 miles (190 km) west of Arequipa or about 375 miles (600 km) southeast of Lima at 2:33 PM MDT, Jun 23, 2001 (3:33 PM local time in Perú). A PRELIMINARY MAGNITUDE OF 7.9 WAS COMPUTED FOR THIS EARTHQUAKE. The magnitude and location may be revised when additional data and further analysis results are available.

No tsunami threat from this earthquake remains. According to the Pacific Tsunami Warning Center, small tsunami waves with maximum wave heights up to 2.5 meters were observed in coastal areas of Perú, Chile, and the Galapagos, and caused some damage in Perú shortly following the earthquake.

Many aftershocks, several of them large enough to have been damaging earthquakes in their own right, have been recorded following this event. The largest so far, recorded on 7 July 2001, had a magnitude (MW) of 7.6, determined by Harvard.
