Major 7.4-Magnitude Earthquake Strikes South Atlantic, Tsunami Alert Issued
On Friday morning, a significant 7.4-magnitude earthquake struck the South Atlantic Ocean, approximately 136 miles south of Ushuaia, Argentina, in the Drake Passage, according to the United States Geological Survey (U.S.G.S.). The earthquake occurred at 8:58 a.m. Eastern Time, prompting experts to issue a tsunami warning for parts of the Chilean coast.
Initial reports indicated a magnitude of 7.5, but this figure may be revised as seismologists continue to analyze data. The U.S. Tsunami Warning System advised that should a tsunami occur, it could produce waves ranging from 3 to 10 feet, with potential landfall at Golfo de Penas in Southern Chile around 11:22 a.m.
The area experienced shake intensity defined as "light" by the U.S.G.S., which notes that the quake might still be felt beyond the designated zones displayed on their updated maps. Aftershocks are common following such significant earthquakes; these smaller quakes can follow the main event for days, weeks, or even longer, sometimes matching or exceeding the initial quake’s magnitude.
Shake data and aftershock details were compiled by the U.S.G.S., reflecting seismic activity in the region. Monitoring efforts continue as scientists gather more information about the event and its aftershocks, which can pose additional risks to already affected areas.
This earthquake serves as a reminder of the dynamic nature of seismic activity in the region, emphasizing the importance of preparedness and awareness regarding natural disasters. Further updates are expected as authorities continue to evaluate the situation.
