Modeling Strombolian eruptions of Karymsky volcano, Kamchatka, Russia

A model is proposed to explain temporal patterns of activity in a class of periodically exploding Stromboliantype andesite volcanoes. These patterns include major events (explosions) which occur every 3^30 min and subsequent tremor with a typical period of 1 s. This two-periodic activity is thought to be caused by two distinct mechanisms of accumulation of the elastic energy in the moving magma...

Sulfur Degassing from Mt. Erebus Volcano, Antarctica

SO2 emission rates from Erebus volcano show periodicity, which directly relates to lava lake convection and magma and conduit processes. Mt. Erebus is a 3794 m stratovolcano with a persistently degassing convecting, phonolite lava lake. Lava lake SO2 emission rates were collected from 1992 to 2003 using the correlation spectrometer (COSPEC) and in 2003 and 2005 using a miniature ultra-violet di...

Flux measurements of explosive degassing using a yearlong hydroacoustic record at an erupting submarine volcano

[1] The output of gas and tephra from volcanoes is an inherently disorganized process that makes reliable flux estimates challenging to obtain. Continuous monitoring of gas flux has been achieved in only a few instances at subaerial volcanoes, but never for submarine volcanoes. Here we use the first sustained (yearlong) hydroacoustic monitoring of an erupting submarine volcano (NW Rota-1, Maria...
