[Regnum] Geologists studying the annual rings of semi-fossil trees found in Yamal have been able to determine the exact date of one of the largest volcanic eruptions in the last 10,000 years. We are talking about the Kikai volcano, which erupted in 5279 BC. This is reported in the German journal Dendrochronologia.
Experts said the discovery could be an important clue for synchronising the chronologies of other eruptions.
The article says that scientists focused on three of the most significant volcanic eruptions over the past 10,000 years: Ilyinsky Volcano in Kamchatka, Mazama in North America, and Kikai in Japan.
The first two volcanoes emitted approximately 150 cubic km, while Kikai exceeded all expectations, with emissions ranging from 300 to 450 cubic km.
"This is several times greater than the volume of eruptions from other volcanoes, including the most powerful eruption of Tambora in 1815," the scientists said.
In their opinion, if the dendrochronologists' assumption about the date of the Kikai eruption is correct, then a significant correction must be made to the chronology of the glacier layers of Greenland and Antarctica, which could change our understanding of climate change.
As reported by Regnum News Agency, the Ebeko volcano on Sakhalin ejected ash to a height of 2.8 km. It is noted that there was no ash fall in Severo-Kurilsk, and residents did not smell hydrogen sulfide. As noted by the Ministry of Emergency Situations, there is no threat to the life of residents.
