A magnitude 5.0 aftershock has rattled southern Puerto Rico, causing some cracks but no reported injuries in a region that has been shaken by continuing quakes for more than a month.
Officials in the southwest coastal town of Guayanilla reported a cracked wall and arch near a municipal pool that had already been closed to the public.
It also prompted re-inspections of homes, schools and other buildings.
Tuesday’s 10:45 a.m. (1445 GMT) quake struck 9 miles (15 kilometers) south-southeast of Guanica at a shallow depth of 4 miles (7 kilometers).
It was felt across the island.
