EXPLOSION SEISMIC STUDIES IN SOUTH KYUSHU ESPECIALLY AROUND THE SAKURAJIMA VOLCANO

The 5 April 2003 vulcanian explosion at Stromboli volcano (Southern Italy): analysis of seismic data

On 5 April 2003 at 07:13 GMT (09:13 local time) a violent vulcanian explosion occurred at Stromboli volcano. At the time of the event an eruptive crisis was ongoing at the volcano with a lava flow outpouring along the Sciara del Fuoco flank. The seismic signals related to the event were recorded by 8 permanent broadband stations and gives informations about the eruption kinematics. An ultra-lon...

Seismic velocity structure in and around the Naruko volcano, NE Japan, and its implications for volcanic and seismic activities

Geofluids is important for understanding volcanic and earthquake generation processes. In this study, we obtained a detailed seismic velocity structure in and around the Naruko volcano, northeastern Japan, using data from a dense seismic observation network. We found a distinct seismic low-velocity zone (LVZ) beneath the Naruko volcano, with a diameter of nearly 10 to 20 km in the lower crust. ...

Application of the Monopole Source to Quantify Explosive Flux During Vulcanian Explosions at Sakurajima Volcano (Japan)

Introduction to an Open Community Infrasound Dataset from the Actively Erupting Sakurajima Volcano, Japan

Continuous thermal monitoring of the 2008 eruptions at Showa crater of Sakurajima volcano, Japan

An infrared thermal monitoring system installed 3.5 km from the Showa crater of Sakurajima volcano, Japan, enabled the capture of continuous thermal waveform data at 1 Hz during two recent episodes of eruptive activity. The eruptions were characterized by a sudden increase in volcanic cloud temperature in the first 2–5 s, followed by gradual cooling over a few minutes. The maximum cloud tempera...
