- Abstract
- The changes in volcanic seismicity regimes on example of the 2006 eruption of the Augustine volcano in Alaska are analyzed in the paper. During the long-term volcanic swarm preceding the eruption, two processes with different seismicity regimes were identified. The first can be associated with general radial deformations caused by an increase in pressure in the underground magma pit; such a regime has a high value of the slope of the magnitude-frequency distribution and a low degree of clustering. The second process, presumably, can be associated with a dike intrusion and local destruction of rock under the pressure of the dike. This process has a slope parameter of the magnitude-frequency distribution close to 1 and shows a high level of clustering before the most significant events, which are followed by lulls.
