Seismological monitoring of the February 2007 effusive eruption of the Stromboli volcano
Stromboli volcano monitoring volcano seismicity
2015/9/2
On February 27, 2007, the Stromboli volcano, which has usually been characterized by moderate explosive activity,started an effusive eruption with a small lava flow down the NW flank. The permanent br...
Development of geothermal field following the 2000 eruption of Usu volcano as revealed by ground temperature,resistivity and self-potential variations
Usu volcano geothermal field ground temperature electrical prospecting selfpotential field hydrothermal circulation
2015/9/2
The 2000 eruption of Usu volcano, NE Japan, took place on the foot of the somma, and formed a cryptodome of 65 m high accompanying numerous faults. We made repeated measurements of ground temperature,...
The ash-fall hazard from a Plinian eruption at Colima Volcano,Mexico
Ash-fall hazard Colima Volcano Mexico
2015/8/28
The historical eruptive activity at Colima Volcano has been characterized by Strombolian and Merapi type eruptions and Vulcanian explosions associated with dome growth, which have ended in a Plinian e...
The flank eruption history of Etna (1610-2006) as a constraint on lava flow hazard
flow hazard Etna
2015/8/27
Data of the flank eruptions of Etna from over the last 400 years were extracted from the new geological map for the lava flow extensions and vent positions, and from the catalogs of historical eruptio...
A GIS-based application for volume estimation and spatial distribution analysis of tephra fallout: a case study of the 122 BC Etna eruption
Geographic Information System (GIS) Tephra fallout Volume estimation Etna
2015/8/18
In this study, we demonstrate the use of a geo-spatial information system for volume estimation of fallout deposits and for identification of syn-eruptive and post-eruptive depositional mechanisms. Fo...
Eruption column height estimation of the 2011-2013 Etna lava fountains
Electromagnetic noise by railways Man-made electromagnetic noise Quiet days noise analysis
2015/8/17
In this paper, we use calibrated images collected by the video-surveillance system of the Istituto Nazionale di Geofisica e Vulcanologia, Osservatorio Etneo, to retrieve the height of the eruption col...
Eruption products of the 1883 eruption of Krakatau and their final settlement
final settlement Krakatau
2015/8/17
Firstly the volume of pyroclastic ejecta during the 1883 eruption of
Krakatau is re-examined. To revise the volume of flow deposits, the author
basically follows Verbeek’s observation while to estim...

Firstly the volume of pyroclastic ejecta during the 1883 eruption of Krakatau is re-examined. To revise the volume of flow deposits, the author basically follows Verbeek’s observation while to estimat...
Eruption patterns of parasitic volcanoes
Parasitic vents Parasitic eruptions Shear fracture model Twin parasitic vents Various patterns of parasitic eruptions
2015/8/14
Eruption patterns of parasitic volcanoes are discussed in order to study their correlation to the activities of their parental polygenetic volcanoes. The distribution density of parasitic vents on pol...
Eruption of South Sarigan Seamount, Northern Mariana Islands: Insights into Hazards from Submarine Volcanic Eruptions
South Sarigan Seamount Northern Mariana Islands:
2015/7/17
The eruption of South Sarigan Seamount in the southern Mariana arc in May 2010 is a reminder of how little we know about the hazards associated with submarine explosive eruptions or how to predict the...
