A strong earthquake struck the Caribbean Tuesday evening, according to the United States Geological Survey.
Originally assessed as a magnitude 7.8, the quake was later downgraded to 7.6 by authorities.
A tsunami advisory was in effect for Puerto Rico and the U.S. Virgin Islands after the quake, according to the Pacific Tsunami Warning Center, but subsequent model forecasts indicated no tsunami threat to those areas.
Hazardous tsunami waves were originally deemed "possible" for coasts of Jamaica, Mexico, Honduras, Cuba, Belize, Costa Rica, Panama, Nicaragua, Guatemala and more — but U.S. authorities subsequently concluded there was no such threat to the region.
The earthquake rattled windows in the Honduran capital of Tegucigalpa roughly 323 miles to the east, but no damage was immediately reported.
It was also lightly felt in the Mexican state of Quintana Roo north of Honduras, according to Mexico's civil protection director.
