Looking at the information this morning, it can be concluded that around 4:00 Latvian time, the secondary wave of changes in atmospheric pressure caused by the eruption of the Tonga volcano “crossed” us. Atmospheric pressure data again “burst” even by 1-2 hPa. https://t.co/KKTUcQbLth

“Looking at the information this morning, it can be concluded that around 4:00 Latvian time, the secondary wave of changes in atmospheric pressure caused by the eruption of the Tonga volcano” crossed us. Atmospheric pressure data again “shattered” even by 1-2 hPa, “Bergstein writes.

Similar observations have been made in Estonia.

“Some time ago, the shock wave of the Tonga volcano also spread across Estonia. This can be seen from the data of the atmospheric pressure – the atmospheric pressure rose sharply and then fell. This is also the case in neighboring countries,” said Cairo Kītsak, a weather forecaster.

It has already been reported that a tsunami hit the Pacific coast of Tonga on Saturday after a strong underwater volcano erupted.

–
Authorities in many parts of the Pacific, including Samoa, Fiji and New Zealand, have issued a tsunami alert urging people to keep their shores afloat due to possible strong and unusual currents and unpredictable surges.
–
Tonga’s meteorological service said a volcanic eruption also occurred on Friday and a 30-centimeter tsunami was then recorded.
–
The eruption of the volcano also took place intermittently at the end of December, but Friday’s eruption was seven times stronger than before, the Tonga Geological Survey said.
–
The noise of Saturday’s volcanic eruption was reported in many parts of the South Pacific, including Fiji, New Zealand and Australia.
–
The capital of Tonga is located just 65 kilometers north of the volcano.
–
The initial eruption lasted eight minutes, releasing ash and smoke several kilometers into the air.
