Scientists discover 91 new volcanoes

Scientists have just discovered 91 new volcanoes, volcanoes that they previously didn't know existed. The new volcanoes were identified in West Antarctica. Together with the previously known 47 volcanoes, this means it's the region with the largest concentration of volcanoes on Earth.

All of the "new" volcanoes were identified under the Antarctica ice sheet with sizes ranging from 100m to 3850 meters. While it's not known whether any, or how many, of the volcanoes are still active, some scientists say that an eruption on the icy continent could have major effects on climate change.

The volcanoes were found by using ice-penetrating radar while looking for hidden peaks of basalt rock (something usually found atop of volcanoes) and analysing the measurements of them. Then the findings were also compared with satellite data as well as geological information and database records.

"After examining existing data on West Antarctica, I began discovering traces of volcanism. Naturally I looked into it further, which led to this discovery of almost 100 volcanoes under the ice sheet." -- Max Van Wyk de Vries, scientist who conducted the study.
