Pacific Volcano Atmospheric Change Detected in Hungary

The atmospheric pressure change caused by the submarine volcanic eruption near Tonga was also felt in Hungary, the National Meteorological Service said this Sunday.

It was in the late afternoon local time (early morning Hungarian time) on Saturday that a volcanic eruption occurred in the area of the Tonga Islands in the western Pacific Ocean, about 17,000 kilometers from Hungary, which caused a tsunami alert. The volcano's ash cloud erupted at a height of 20 kilometers and its huge roar could be heard more than a thousand kilometers away.

The sudden surge of atmospheric pressure traveled around the planet and was felt at every point on Earth. The meteorological service said that measuring stations in Hungary also recorded the sudden pressure change. "The pressure disturbance passed through all the stations, typically causing changes between 0.5 and 1 hectopascal, with one or two locations producing changes of more than 1 hectopascal".

Interestingly, the meteorological service also pointed out that since the shock wave reached Hungary from two directions, the noise was observed twice in the measurements.

The authorities said on Saturday that a tsunami alert had been issued in the South Pacific after a submarine volcano erupted near Tonga. The eruption of the Hunga-Tonga-Hunga-Ha'apai volcano has led to a tsunami in Tonga.
