Informational

A magnitude-3.8 offshore earthquake struck west of Mayaguez, Puerto Rico, at about 13:43 on June 21. The epicenter was approximately 9 km (5 miles) southwest of Stella. The quake struck at a depth of 88 km (55 miles), and light shaking was probably felt throughout western Puerto Rico. There have been no initial reports of damage or casualties due to the earthquake; significant damage is unlikely. It could take several hours for authorities to conduct comprehensive damage assessments, especially in remote areas. Aftershocks are likely over the coming hours. The event has not prompted any tsunami advisories.

Officials may temporarily shut down transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.

Consider vacating multistory or unreinforced buildings in areas near the epicenter until authorities assess their structural integrity. Due to the potential for landslides, seek updated information on road conditions before driving in elevated areas in the affected region. Anticipate localized transport disruptions, as authorities are likely to inspect infrastructure for damage after aftershocks.
