Japan has the amazing beauty of nature and a four-season climate that reflects the country’s geography. As a volcanic country that locates to the east end of the Eurasian continent and faces the Japan Trench and Pacific Ocean, Japan has also experienced a large number of natural disasters. Over a long period of history, people in Japan have experienced and overcome earthquakes, tsunami, typhoon...

Crater size–frequency analyses have shown that the largest volcanic plains deposits on Mercury were emplaced around 3.7 Ga, as determined with recent model production function chronologies for impact crater formation on that planet. To test the hypothesis that all major smooth plains on Mercury were emplaced by about that time, we determined crater size–frequency distributions for the nine next...

the lut block in eastern iran is a micro-continental block within the convergent orogen between the arabian, eurasian and indian plates. large areas of the north-central, eastern, and western lut block are covered by volcanic rocks of paleogene, neogene and quaternary age.  peak volcanic activity took place in the north-central part of the lut block during the eocene, and then dramatically decr...

The determination of areas exposed to new eruptive events in volcanic regions is crucial for diminishing consequences in terms of human causalities and damages of material properties. In this paper, we illustrate a methodology for defining flexible high-detailed lava invasion hazard maps which is based on an robust and efficient Cellular Automata model for simulating lava flows. We also present...

During Earth's history, species extinction has probably been caused by modifications of the physical environment after impacts such as meteorites or volcanic activity. On the contrary, the actual extinction of species is mainly a result of human activities, namely any form of land use that causes the conversion of vast areas to settlement, agriculture, and forestry, resulting in habitat destruc...

The ecological and geological responses following the May 18, 1980, eruption of Mount St. Helens are all about change: the abrupt changes instigated by geophysical disturbance processes and the rapid and gradual changes of ecological response. The explosive eruption involved an impressive variety of volcanic and hydrologic processes: a massive debris avalanche, a laterally directed blast, mudfl...

We investigate the possibility to apply differential SAR interferometry (DIFSAR) techniques to analyse long term phenomena occurring in volcanic areas. The considered test site is represented by the Etna volcano area located in southern Italy; presented DIFSAR experiments show the existence of a long term deformation effect that can be interpreted as an actively growing anticline, beneath the u...
