5.4-magnitude earthquake strikes southern Puerto Rico

SAN JUAN, Puerto Rico — A 5.4-magnitude earthquake struck near southern Puerto Rico on Saturday, briefly knocking out power and forcing the relocation of at least 50 families on an island where some people still remain in shelters from quakes earlier this year.

There were no immediate reports of casualties.

The U.S. Geological Survey said the quake hit at a depth of 5.6 miles near the city of Ponce and the towns of Guanica and Guayanilla, where hundreds of homes were destroyed by a quake in early January that killed one person and caused millions of dollars in damage.

Most of the damage was reported in Ponce, about 75 miles southwest of San Juan.

Several aftershocks hit Puerto Rico’s southern region, including a 4.9-magnitude one.
