Simulation of the Eruption Source for the South Sakhalin Mud Volcano in 2011 Based on GPS Observations

摘要

Mud volcanism is a unique natural phenomenon of a great interest to geology and geophysics. It is supposed that mud volcanoes are indicators of geodynam-ics in the Earth's interior. However, there are only some general ideas about mud volcanoes [1-4], and the problems related to this natural phenomenon have no unambiguous and completely valid solution. Strong eruptions of mud volcanoes cause displacement and deformation of the Earth's surface. The present communication discusses how the horizontal and vertical displacements of the Earth's surface occurred resulting from the 2011 eruption of the South Sakhalin mud volcano and revealed on the basis of GPS observations for the first time allowed us to simulate the eruption source.
