Eruption at Beziminay volcano on Kamchatka Peninsula Eruption to about 15,000m-Weathernews

A large-scale eruption occurred at Beziminay volcano on the Kamchatka Peninsula on the evening of Saturday, May 28th. Observations by local authorities (KVERT) surveillance cameras indicate that the eruption has reached an altitude of 15,000 m.

* The Japan Meteorological Agency announces extraordinary information at 18:05 and monitors whether a tsunami like the one during the volcanic eruption of Tonga in January will occur.

Beziminay volcano has frequently caused large-scale eruptions since 1955, and has continued to be active in recent years. Although the scale of the eruption cannot be compared only by the height of the eruption, in March 2019, an eruption that raised the eruption to the same extent as this time occurred.

According to the current view of Weathernews, the possibility of tide level changes (tsunami) due to air vibration is low because the crater is far from seawater and lake water and past cases.

A surveillance camera jointly installed by Weathernews and KVERT also shows the eruption rising high.

Camera position

The mountain of Mt. Fuji in the center of the camera image is “Mt. Klyuchevskaya” (elevation 4750 meters), and there is a crater of Bezimiany hidden behind it.

Eruption is flowing southeast

The eruption is flowing to the southeast and is spreading toward the Kuril Islands, which can be confirmed from the image of the meteorological satellite Himawari-8.

This image is a composite of the observation results of multiple wavelengths taken by the satellite, and the part analyzed as a volcanic ash cloud looks orange. Weathernews operates an AI volcanic ash detection system to constantly monitor the presence or absence of impact on aircraft.

Depending on the situation of the eruption, it may affect the aircraft

When a large amount of volcanic ash is released into the atmosphere by the eruption, the engine of the airplane that inhaled it will stop, and the window glass of the cockpit will be damaged and the visibility will be obscured, which will have a serious impact on the operation of the aircraft. May cause.

Depending on the situation of volcanic ash in the future, delays may occur due to changes in the routes of passenger planes arriving and departing near the Kamchatka Peninsula, as well as international flights connecting North America and Europe and Asia that pass through the vicinity.

Semeru Volcano (elevation 3676m) is a volcano in the eastern part of Java Island, Indonesia. Similar to the active volcanoes scattered around Indonesia, it often causes eruptions that erupt more than 10,000 meters, and can also generate pyroclastic flows and lahars.

In this eruption, it seems that the eruption was blown up to near the upper end of the troposphere, and the eruption was confirmed from the meteorological satellite Himawari.

The Philippine Institute of Volcanology and Earthquakes (PHIVOLCS) has announced to the public that the alert level for eruptive activity of Taal Volcano is set in 6 levels from 0 to 5. PHIVOLCS gradually raised the alert level to 4 at 20:30 Japan time, the second from the top.

Ashfall has been confirmed in the surrounding area, and local authorities have issued evacuation advisories to the Taal Volcano Island and the areas of Agonshiro and Laurel, Batangas, citing the danger of pyroclastic flows and tsunamis.

The Japan Meteorological Agency is investigating the possibility of tide level changes due to the eruption.

When a large-scale eruption occurred at the volcano Hunga Tonga-Hunga Haapai in Tonga in January this year, an unusual tsunami occurred and the tsunami reached Japan.

It is unknown whether the eruption of Beziminay volcano will cause a tsunami, but the Japan Meteorological Agency has announced that it will monitor changes in tide levels.

According to the current view of Weathernews, the possibility of tide level changes (tsunami) due to air vibration is low because the crater is far from seawater and lake water and past cases.
