Nisyros volcano crack caused by heavy rain

An ominous, 238-meter-long crack that appeared on Sunday on the volcano of Nisyros in the Dodecanese was probably caused by heavy rainfall rather than a reawakening of the volcano, experts said yesterday. The lack of gas or smells emanating from the crack, as well as the fact that it is one kilometer north of the volcano crater point to the conclusion that the rain carried earth into a blind crack, revealing it, Athens Geodynamic Institute geologist Athanassios Ganas told Kathimerini. Yesterday, Greece’s civil defense authorities sent a team of geologists and vulcanologists to investigate the crack, which is between 2 and 2.5 meters wide and up to 5 meters deep. The 698-meter high volcano last erupted in 1888. It was also active in 1873, 1871, and possibly 1422.
