Kamchatka and the Kuril Islands are considered the most anomalous regions of Russia, followed by Sakhalin, Lake Baikal, Altai, Sayans, Southern Urals, North Caucasus, Crimea and the Kaliningrad region. Between 60 and 80% of powerful earthquakes occur precisely in such areas, the head of the seismic hazard laboratory at the Institute of Earth Physics. O.Yu. Schmidt RAS, Doctor of Physical and Mathematical Sciences Dmitry Zavialov.
Anomalous means that differ in their statistical characteristics from those of other areas of the region considered seismically active. All these regions were identified using a technique developed by IPE RAS experts in the mid-1990s.
“For more than 30 years, we have been testing it in various seismically active regions of the world. In the output, it gives maps of the distribution of the conditional probability of a strong earthquake. The technique uses a number of prognostic features, and these features are mainly seismological, i.e. the behavior of weak earthquakes in anticipation of a strong earthquake. is based on scrutiny,” explained Zavyalov.
