A preliminary 7.1 magnitude earthquake was reported Wednesday evening in northwest Venezuela, according to the U.S. Geological Survey.

The earthquake was centered 17.6 miles southeast of the Venezuelan town of Montalbán, according to the USGS, and struck at a depth of 8.2 miles.

It triggered tsunami advisories in Puerto Rico and the Virgin Islands, according to the National Weather Service's U.S. Tsunami Warning System.

"Based on all available data, there is a tsunami threat to Puerto Rico and the Virgin Islands of sea level fluctuations and strong ocean currents that could be a hazard along coasts, beaches, in harbors and in coastal waters," the weather service said.

The possible extent of the damage and the injury toll of the earthquake was still unclear.
