**Strong Earthquake Strikes South Atlantic, Tsunami Threat Recedes**

**[Date – Based on provided information: October 11, 2024 (Estimated)]**

A significant 7.6-magnitude earthquake rattled the South Atlantic Ocean on Friday, triggering initial concerns about potential tsunami waves along the coast of Chile. The United States Geological Survey (USGS) reported the seismic event occurred at 4:29 p.m. Eastern time.

While Chilean authorities issued alerts shortly after the quake, they later determined that dangerous tsunami waves were unlikely to materialize. The U.S. National Tsunami Warning Centers in Alaska and Hawaii also confirmed there was no tsunami threat to Hawaii, or the east and west coasts of Canada and the United States.

Seismologists are currently reviewing available data and may revise the earthquake’s initially reported magnitude. The USGS may also update shake-severity maps as more information is collected.

Authorities are monitoring for aftershocks, which are common following major earthquakes. These smaller tremors, representing adjustments along the fault line, can occur for days, weeks, or even years after the initial event and can potentially cause further damage to affected areas.

[**Note:** Since the article mentions aftershocks data being available as of Saturday, Oct. 11 at 1:14 p.m. Eastern, I’ve dated the news article based on the assumption that the earthquake happened on Friday, October 10th of the current year, making the article date October 11th. This might need adjustment depending on the actual year of the event.]
