The eruption of the volcano Tonga "voiced" based on satellite data

The eruption of the underwater volcano Hunga Tonga Hunga Haapai began on January 15, 2022 and caused a series of

atmospheric emissions and tsunamis that swept across the world. The eruption created the largest volcanic plume in history.

The researchers used wind data,taken by the European Space Agency's Aeolus remote sensing satellite to reconstruct the sound of one of the shock waves from an underwater volcano.

The collected data was converted into audioa range spanning six piano octaves. The highest sound can be heard at approximately 01:18. This moment in the audio recording corresponds to when the dust plume of the eruption reached its peak - more than 20.5 km. 

Hunga-Tonga-Hunga-Haapai volcano eruptioncaused massive destruction on the territory of the islands of Tonga, located in the Pacific Ocean. Volcanic material rose to a height of up to 58 km into the atmosphere. At the same time, as a result of the eruption, an almost 15-meter tsunami was formed, which hit the coast, destroying villages and creating a sonic boom that circled the globe twice.
