🌋 - NATURAL DISASTERS

Hidden Magnitude-8.2 Earthquake Deemed Source of Mysterious 2021 Tsunami.

A 47 km-deep magnitude 7.5 earthquake that struck the south Atlantic in 2021 was previously thought to have started a global tsunami – scientists now believe it was caused by a sequence of five earthquakes spread out over a few minutes.

The 7.5-magnitude earthquake, which hit near the South Sandwich Islands in 2021, had initially puzzled scientists - as the epicenter was believed to be far too deep to initiate a tsunami.

A new study has revealed a third shallow, “almost invisible” magnitude 8.2 quake, accounted for 70% of the energy released during the event and the resultant global tsunami.
