The research will continue in In summer and autumn 2023.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. The Russian Geographical Society (RGS), the Northern Fleet and scientists of the Russian Academy of Sciences (RAS) joint expeditions have found traces of ancient earthquakes in Western and Eastern Taimyr, Wrangel Island, Novaya Zemlya and Franz Josef Land.

Scientists conducted a study on seismotectonics on the Alexandra Land Island. With the help of broadband seismic stations and georadars, they studied deep structures, and also conducted seismic experiments on the ice plate. This was reported in the Russian Geographical Society with reference to a senior researcher at the Institute of Physics of the Earth named after O.Y. Schmidt RAS Ruslan Zhostkov.

“It is too early to talk about any results. We were able to collect a fairly large amount of experimental data, which we will process and study in order to understand how strong earthquakes can occur in the Arctic. The main thing is not that we give some answers, but that we raise questions, because the Arctic, as it turned out, is not quite the same as we are used to seeing it”, said Ruslan Zhostkov.

One of the expedition objectives is to issue recommendations on possible methods and forms of economic activity in the Arctic. Those who develop the Arctic must have all the data on seismic hazard, patency, what processes are possible associated with the melting of glaciers, and so on.

The expedition to Franz Josef Land in 2023 was a continuation of the scientific work carried out on the archipelago in 2021, when scientists combined geological and geomorphological studies with counting polar bears.

In summer or early autumn, the Russian Geographical Society organizes a second expedition, and scientists will conduct research that was impossible in winter.

Earlier, Russian scientists hypothesized that the Arctic could heat up sharply due to powerful earthquakes. Researchers have unraveled the mystery of the disappearing Arctic reservoir in Krasnoyarsk. Also an unknown crustaceans species was found in the Putorana Plateau mountain lakes.
