The shock wave was formed after a volcanic eruption on the island of Tonga in the Pacific Ocean. At 20.23 she arrived at Kasprowy Wierch, the Institute of Meteorology and Water Management reported on Saturday evening.
A volcanic eruption in the Pacific Ocean was recorded on Saturday near the Tonga archipelago in the South Pacific. The eruption caused a rise in water and a tsunami that hit the coast of Japan on Saturday evening into Sunday.
According to IMGW on Saturday evening, the shock wave formed after the volcanic eruption and reached Kasprowy Wierch. “Interesting fact: The shock wave (air pressure) formed after the volcanic eruption on the island of Tonga in the Pacific Ocean reached Kasprowy Wierch at 20:23 local time. This can be seen on the pressure graph. The eruption occurred around 06:00 in the morning,” reports IMGW.
As a result of a volcanic eruption on the east coast of the Samoan Islands, which are part of the territory of American Samoa, the sea level rose by about 70 cm.
Tsunami in Japan
On the other hand, on the night from Saturday to Sunday, local time, a tsunami hit the coast of Japan as a result of the explosion. The Japan Meteorological Agency has warned of waves that can reach up to three meters in some places.
In the city of Amami in southwestern Japan, a tsunami up to 1.2 meters high is already being observed. Smaller waves of less than 1 meter have been recorded along wide stretches of the coast of Hokkaido, Kyushu and Okinawa, the Kyodo news agency reported.
