01.03.2018

On February 28, 2018, a lecture «Active Volcanoes of the Kuril Islands» was delivered in the Sakhalin Regional Museum within the framework of the lecture series «Natural History of Sakhalin and the Kuril Islands» by Rafael Vladimirovich Zharkov, PhD in Geography, Leading Researcher of the Laboratory of Volcanology and Volcanic Hazard, Institute of Marine Geology and Geophysics, FEB RAS (IMGG FEB RAS, Yuzhno -Sakhalinsk), a member of the Russian Geographical Society. The lecture was attended by museum specialists, students of Yuzhno — Sakhalinsk universities, as well as people interested in this topic.
At the lecture the students learned about the geographical peculiarities of the Kuril Islands and found out that there are more active volcanoes than in Kamchatka, namely about 40. Volcanoes of the Kuril Islands are characterized by eruptions of the most dangerous, explosive type, which can form «scorching clouds» and produce pyroclastic and mud-currents. The radius of the affected zone can reach 25–30 km. The most potentially dangerous volcanoes are Mendeleev, Golovnin, Tyatya, Ivan the Terrible, Baransky, Chirip, Chikurachki, Ebeko.
Rafael Vladimirovich showed satellite images of volcanoes. Satellite images allow you to assess the movement of ashes after eruptions, which sometimes reach the Khabarovsk Territory. The satellite images of lava flows demonstrated by the lecturer, allow attendees to estimate the changes, and most often, the increase in the area of the coastal landscape.
At the end of the lecture Rafael Vladimirovich told the public about health benefits of explosive eruption products which are used for recreation and health (thermal and mud sources).
