Increasing attention has been paid to multi-hazards in environmental disaster studies produced during the last decade. Multi-hazard focus on occurrence, interaction and effect of several natural hazards same region. Despite increasing number multi-hazard studies, few investigations have focused global-scale events. With aim closing this gap, our study focuses identification periods 1.5 million ...

Airborne volcanic ash can pose a hazard to aviation, agriculture, and both human and animal health. It is therefore important that ash clouds are monitored both day and night, even when they travel far from their source. Infrared satellite data provide perhaps the only means of doing this, and since the hugely expensive ash crisis that followed the 2010 Eyjafjalljökull eruption, much research h...

Catastrophic collapses of the flanks of stratovolcanoes constitute a major hazard threatening numerous lives in many countries. Although many such collapses occurred following the ascent of magma to the surface, many are not associated with magmatic reawakening but are triggered by a combination of forcing agents such as pore-fluid pressurization and/or mechanical weakening of the volcanic edif...

This paper examines the philosophy and evolution of volcanological science in recent years, particularly in relation to the growth of volcanic hazard and risk science. It uses the lens of Science and Technology Studies to examine the ways in which knowledge generation is controlled and directed by social forces, particularly during eruptions, which constitute landmarks in the development of new...

Volcanic ash has been widely used as unique independent marker horizons for dating and synchronizing paleoenvironments archeological records. Here, we report a series of key widespread late Pleistocene to Holocene tephras from lake sequence in southern China that have significant potential paleoenvironmental records East Asia. Translatitudinal paleoclimatological, paleoenvironmental, correlatio...

[1] The 2002–2003 Mount Etna eruption and the associated deformation provide a unique possibility to study the relationships between volcanism and volcano instability. The sequence started with movement of the eastern volcano flank and was associated with earthquakes and the formation of surface ruptures. Then the eruption occurred from fissures at the north and south rift zones and was followe...

A detailed study of the aftershocks of the earthquake that devastated Managua, Nicaragua, on December 23, 1972, shows that the earthquake occurred on a fault that strikes N30 ° to 35°E and dips 80 ° to 90°E, and that this fault moved in a leftlateral sense over a zone about 15 km long extending from shallow depth to a depth of 8 or 10 km. The extensive damage accompanying an earthquake with bod...
