In March 1996 an intense swarm of volcano-tectonic earthquakes (∼3000 felt by local residents, Mmax = 5.1, cumulative moment of 2.7×1018 N m) beneath Akutan Island in the Aleutian volcanic arc, Alaska, produced extensive ground cracks but no eruption of Akutan volcano. Synthetic aperture radar interferograms that span the time of the swarm reveal complex island-wide deformation: the western part of the island including Akutan volcano moved upward, while the eastern part moved downward. The axis…

Surface deformation associated with the March 1996 earthquake swarm at Akutan Island, Alaska, revealed by C-band ERS and L-band JERS radar interferometry
In March 1996, an intense earthquake swarm beneath Akutan Island, Alaska, was accompanied by extensive ground cracking but no eruption of Akutan volcano. Radar interferograms produced from L-band
Seismic and geodetic investigation of the 1996-1998 earthquake swarm at Strandline Lake, Alaska
SUMMARY Microearthquake swarms occur frequently in volcanic environments, but do not always culminate in an eruption. Such non-eruptive swarms may be caused by stresses induced by magma intrusion,
Seismic Swarm Associated With the 2008 Eruption of Kasatochi Volcano, Alaska
[1] An energetic seismic swarm accompanied an eruption of Kasatochi Volcano in the central Aleutian volcanic arc in August of 2008. In retrospect, the first earthquakes in the swarm were detected
Mechanism of the 1996–97 non-eruptive volcano-tectonic earthquake swarm at Iliamna Volcano, Alaska
A significant number of volcano-tectonic (VT) earthquake swarms, some of which are accompanied by ground deformation and/or volcanic gas emissions, do not culminate in an eruption. These swarms are
Dynamic deformation of Seguam Island, Aleutian Islands, Alaska, 1993–2000: Implications for magmatic and hydrothermal processes
[1] The most recent volcanic eruption on Seguam Island was detected in December 1992 and lasted until July or August of 1993. A series of radar interferograms, generated from imagery collected by the
Studies of volcanoes of Alaska by satellite radar interferometry
Interferometric synthetic aperture radar (InSAR) has provided a new imaging geodesy technique to measure the deformation of volcanoes at tens-of-meter horizontal resolution with centimeter to
