Seismically and geodetically determined nondouble-couple source mechanisms from the 2000 Miyakejima volcanic earthquake swarm
[1] The volcanic eruption on Miyakejima, Japan, in 2000 was marked by the largest earthquake swarm ever recorded in Japan, a seismicity migration accompanying a dike intrusion as the dike propagated from Miyakejima to the northwest, and formation of a caldera on Mount Oyama on Miyakejima. In this study, we propose a seismic source model which can be used to model both seismic and geodetic displ...
متن کاملJovian Dust Streams: A monitor of Io’s volcanic plume activity
Streams of high speed dust particles originate from Jupiter’s innermost Galilean moon Io. After release from Io, the particles collect electric charges in the Io plasma torus, gain energy from the co-rotating electric field of Jupiter’s magnetosphere, and leave the Jovian system into interplanetary space with escape speeds over 200 km s. Galileo, which was the first orbiter spacecraft of Jupite...
متن کاملCharge structure in volcanic plumes: a comparison of plume properties predicted by an integral plume model to observations of volcanic lightning during the 2010 eruption of Eyjafjallajökull, Iceland
Observations of volcanic lightning made using a lightning mapping array during the 2010 eruption of Eyjafjallajökull allow the trajectory and growth of the volcanic plume to be determined. The lightning observations are compared with predictions of an integral model of volcanic plumes that includes descriptions of the interaction with wind and the effects of moisture. We show that the trajector...
متن کاملUnmanned Aerial Vehicles for Volcanic Plume Sampling
Small, inexpensive unmanned aerial vehicles (UAVs) constructed from off the shelf components can be used in coordinated teams to sample the airspace and provide an accurate mapping of distributed particles from recent volcanic eruptions . The UAVs are constructed from hobbyist RC planes, where the remote control is bypassed by a programmable Arduino autopilot. These UAVs are equipped with low p...
متن کاملSelf-charging of the Eyjafjallajökull volcanic ash plume
Volcanic plumes generate lightning from the electrification of plume particles. Volcanic plume charging at over 1200 km from its source was observed from in situ balloon sampling of the April 2010 Eyjafjallajökull plume over Scotland. Whilst upper and lower edge charging of a horizontal plume is expected from fair weather atmospheric electricity, the plume over Scotland showed sustained positiv...
