Volcanic eruption breaks records with speeds close to the limit

A new study has found that a recent volcanic eruption has shattered records for producing powerful waves close to the 'limit'.

On January 15, 2022, an underwater volcano erupted, that caused a violent explosion that shook the island of Tonga.

The underwater volcano named the Hunga Tonga is a submarine volcano that is located approximately 40 miles north of Tonga's capital, Nuku'alofa. Upon eruption, the massive underwater volcano immediately created a four-foot-tall tsunami that devastated the Tongan islands, wiping out most houses and structures. The Tongan government declared the event an "unprecedented disaster".

The explosion from the volcano was so large that it was detected in space by a NASA satellite. The above video was captured by the GOES West Earth-observing satellite that is operated by the U.S. National Oceanic and Atmospheric Administration (NOAA), and it showcases a large cloud of smoke suddenly erupting. The large plume of smoke reached 36 miles in altitude, and the power of the explosion was estimated to be ten megatons of TNT exploding, or more than 500 times as powerful as the nuclear bomb that was dropped on Hiroshima.

Now, a recent study published in the journal Nature details the speed of the pressure waves that were created from the explosion, and according to the study's lead author Corwin Wright, a Royal Society University Research Fellow based at the Centre for Space, Atmospheric and Oceanic Science at the University of Bath in the U.K., these atmospheric pressure waves reached speeds of 720 miles per hour, which is "very close to the theoretical limit".

Notably, the team states in the study that the Hunga explosion produced atmospheric waves that have broken all previous records for explosive volcanic events, and that the volcanic event is one of the most explosive volcanic events in modern history. Furthermore, the researchers state that the atmospheric waves that were produced traveled the Earth at least six times. The team also said that with newly acquired data, they will be able to develop and improve "our weather and climate models."
