Interactive Map Reveals Impact of 7.6-Magnitude Earthquake in South Atlantic Ocean

A powerful 7.6-magnitude earthquake struck the South Atlantic Ocean, triggering alerts for coastal regions.

Earthquake Impact on the South Atlantic Ocean

On Friday, a significant earthquake occurred in the South Atlantic Ocean, measured at a magnitude of 7.6. The United States Geological Survey (U.S.G.S.) recorded the quake at 4:29 p.m. Eastern time.

Tsunami Alerts and Warnings

The initial tremor raised concerns about potential tsunami waves along Chile’s coastline in South America. However, after a brief period, authorities confirmed that such waves were unlikely.

• The U.S. National Tsunami Warning Centers in Alaska and Hawaii declared no tsunami threat for Hawaii.
• No danger was identified for the eastern and western coasts of Canada and the United States.

Aftershock Analysis and Seismic Activity

Aftershocks often follow a major earthquake as smaller seismic events. These occur along the same fault line that slipped during the initial quake.

Seismologists continue to gather data to possibly adjust the earthquake’s magnitude. Such events can happen within 100 miles of the original site and may persist for days, weeks, or even years.

Visualizing Earthquake and Aftershock Data

The U.S.G.S. updated the earthquake severity map to reflect real-time data on shaking intensity. Based on the Modified Mercalli Intensity scale, these maps delineate areas experiencing light to severe shaking.

Maps and charts provide visual representations of both the main earthquake and any aftershocks within 100 miles for up to seven days post-event.

Emegypt will continue to monitor and report on developments as new information surfaces about this seismic event.
