Global earthquakes in the 2022 first half according to the GS RAS

Abstract

An analysis of the seismicity of the Earth in the 2022 first half at the level of strong earthquakes with magnitudes mb≥6.0 according to the Alert Service of the Geophysical Survey RAS are given. In addition, added information about 59 earthquakes in Russia and adjacent territories, felt in the settlements of the Russian Federation. For 15 strong earthquakes within one or two days after their occurrence, Information messages were publishing; information about the focal mechanisms was calculated and presented. During the period under review, the strongest earthquake on the globe with MS=7.0 (Mw=7.3) occurred on March 16 on the east coast of Honshu Island, Japan. The greatest loss of life and material damage during the study period was caused by a catastrophic earthquake with MS=6.4 (Mw=6.1), which occurred on June 21 on the border of Afghanistan and Pakistan. Because of the earthquake, 1,500 people were killing and more than 2,000 people were injured. On the territory of Russia, the strongest earthquake was on April 24 with MS=5.8 (Mw=6.2) east of the Kuril Islands. With the greatest intensity of concussions (6 points) in the settlements of Russia, an earthquake was felt on June 8 with mb=5.4 (MS=5.2), which occurred in the water area of Lake Baikal. There was a sharp decrease in the seismic energy released in the first half of 2022 on the globe after a surge in the previous six months.
