Seismic Activity under the Volcanic Area

Mapping Seismic Attenuation Structures of the Volcanic Area in Northern Taiwan

Three-dimensional body-wave attenuation structures beneath the volcanic area in northern Taiwan are obtained by using the seismic tomographical inversion method. In total, both Pand S-waves of 137 local earthquakes with magnitudes between 2.0 and 5.0 were analyzed. Those events with 3-component digital seismograms were recorded by the Central Weather Bureau Seismographic Network (CWBSN). The re...

Seismic structure of the Tengchong volcanic area southwest China from local earthquake tomography

Seismic activity of the Nevados de Chillán volcanic complex after the 2010 Mw8.8 Maule, Chile, earthquake

Geophysical imaging of subsurface structures in volcanic area by seismic attenuation profiling

Geophysical imaging by using attenuation property of multichannel seismic reflection data was tested to map spatial variation of physical properties of rocks in a volcanic area. The study area is located around Miyakejima volcanic island, where an intensive earthquake swarm was observed associated with 2000 Miyakejima eruption. Seismic reflection survey was conducted five months after the swarm...

Influence of volcanic activity at Mauna Loa, Hawaii, on earthquake occurrence in the Kaoiki Seismic Zone

[1] The Kaoiki Seismic Zone at Mauna Loa’s east flank is the locus of some of the largest earthquakes on Hawaii. In this paper we examine the link of those earthquakes to volcanic activity at Mauna Loa. We calculate the changes of Coulomb failure stress along the Kaoiki faults for typical volcanic events at Mauna Loa volcano. We simulate the dislocation associated with the 1950 eruption at the ...
