On Sunday, June 4, a 3.3-magnitude earthquake occurred approximately 121 miles from Gulf Shores, Alabama, according to the U.S. Geological Survey.

The rare seafloor earthquake occurred shortly after 11 p.m. Sunday night and occurred in an area with no know fault lines or tectonic boundaries, according to a report from the Biloxi Sun Herald. USGS data shows it was centered just over 3 miles below the seafloor.

A geologist with USGS said the quake in that area is rare, but that there have been quakes near that area in the past.

Venice, Louisiana, is the closest town to where the quake occurred. No reports of feeling the quake have been reported.

At 3.3 magnitude, it likely would not have caused fracturing of the seafloor and was not strong enough to generate tsunami activity, experts say.

More than 1,000 miles across the Gulf of Mexico, a much larger earthquake with a preliminary magnitude of 4.9 struck southern Haiti early Tuesday, killing at least four people and injuring 36 others, authorities said. The quake struck before dawn near the southwestern coastal city of Jeremie at a depth of six miles (10 kilometers), according to the U.S. Geological Survey.
