Kudryavy volcano (Kuriles): increase in steam emissions
mercredi août 02, 2017 12:05 | AUTEUR : T
The Institute of Volcanology and Geodynamics (Russian Academy of Natural Science) reported that during the morning of 31 July volcanologists working on Kudryavy, a stratovolcano of the Medvezhia volcanic complex, noted a sharp increase in the volume of vapor-and-gas emissions, with a plume rising more than 1 km.
The emissions rose from a new crater, Malysh, that was formed after the 1999 phreatic eruption. A significant increase in temperature (an average of 100 degrees Celsius) was measured at fumarolic sites, and new high-temperature areas were noted.
Crusts of native sulfur at the boundaries of high-temperature areas were melting and burning. Two people at the top of the volcano and workers at the main base camp (3.5 km S) self-evacuated.
