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...
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 products of the 1883 eruption of Krakatau and their final settlement

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...
Eruption patterns of parasitic volcanoes
Parasitic vents Parasitic eruptions Shear fracture model Twin parasitic vents Various patterns of parasitic eruptions
