Eighth lake with volcanic lava discovered on subantarctic island

Until now, volcanologists were aware of the existence of seven lakes, stably filled with volcanic lava. A team of scientists from the British Antarctic Survey and University College London has been searching for another volcanic lake for more than 30 years. And finally, their long-term expectations came true: the eighth lava lake was discovered on Mount Michael stratovolcano on one of the remote South Sandwich Islands - Saunders Island.

The main problem in collecting evidence is the great remoteness of the island and the inaccessibility of Mount Michael, which is almost 1000 meters high. Modern satellite imagery technologies helped to solve it. In particular, thanks to data from the Copernicus Sentinel-2, Landsat and ASTER satellites, the Terra research team finally proved the presence of a stable lake of lava inside Mount Michael with a temperature of about 1000 ° C.

The previous seven lava lakes are located: in the area of ​​Mount Nyiragongo (DR Congo), Erta Ale (Ethiopia), near Mount Erebus (Antarctica), Ambrim and Mount Yasur (Vanuatu), Kilauea (Hawaii) and Masaya (Nicaragua).
