[Regnum] After a recent strong earthquake with a magnitude of 8.7–8.8, the southern part of the Kamchatka Peninsula shifted almost 2 m in a southeasterly direction. This was reported on Tuesday, August 5, by the press service of the Kamchatka branch of the Geophysical Service of the Russian Academy of Sciences.
The scientists clarified that they had carried out a preliminary calculation based on the results of geodynamic observations.
"It turned out that we all went southeast quite well. The maximum coseismic displacements after the July 30 earthquake were observed in the southern part of the peninsula. There they amounted to almost 2 m, which is comparable to the horizontal displacements after the 2011 earthquake in Tohoku, Japan," the service's Telegram channel says.
At the same time, the Petropavlovsk cluster of stations, including Petropavlovsk-Kamchatsky, shifted to a slightly smaller distance, the press service added.
Earlier, on July 30, an earthquake with a magnitude of 8.7–8.8 occurred in the Kamchatka Territory, which was the strongest since 1952. As a result, a tsunami threat was declared in the region, and residents were asked not to approach the coast in dangerous areas.
A high alert regime was also introduced in Kamchatka, and a state of emergency was declared in the North Kuril District of the Sakhalin Region. The earthquake triggered a tsunami in the Pacific Ocean, which is why a threat was declared in the coastal areas of Japan, the United States, the Philippines, and several Latin American countries.
Corresponding Member of the Russian Academy of Sciences, Director of the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences Alexey Ozerov said on August 4 that recent strong earthquakes in Kamchatka caused volcanic activity. According to the scientist, the Avachinsky giant was the first to become active, throwing out steam and gas columns up to 300 meters high. Then, an ash column up to 6 km high formed in the Klyuchevskoy volcano, and a lava flow began to pour out onto the slope. The Krasheninnikov volcano became active on August 3, Ozerov specified.
