Why do earthquakes occur before a volcano erupts? How are igneous rocks formed from a subduction zone? How do volcanoes transfer energy? How does magma composition affect a volcanic eruption? How does a volcano form? How is geological erosion different from accelerated erosion?
Does mining cause landslides to occur? If so, how? How does political corruption affect the economy? How does geography affect culture? How does human geography affect physical geography? How does the Great Wall of China affect China's economy? How does a high unemployment rate affect the ...
layers of lava flows alternating with ash and rock rubble build the cone. That ashy rubble – "pyroclastic" material derived from lava and rock blasted apart in a violent eruption – would normally be scoured away by erosion,
The severity of the eruption depends mostly on the composition of the magma. The first question to address is: why does the magma erupt at all? The erupting force generally comes from internal gas pressure. The material that forms magma contains a lot of dissolved gases -- gases that have ...

通读全文,结合第一段的“A new study showed evidence of how coal burning which was caused by a volcanic eruption resulted in climate change in Siberia, It discovered the first direct evidence of how extensive burning of coal in Siberia caused the Permian-Triassic(二叠纪至三叠纪)Mass Extinction ...
the mantle, particularly along fault lines, a volcanic eruption is very likely to occur. Fault lines are the weak areas, cracks, or openings in the earth’s crust. In the eruption process, the molten material turns into lava when it gushes out through the openings onto the earth’s ...
Second, we should take protective measures and make necessary preparations to ensure the safety of human life and property so that, when a disaster does happen, its damage can be controlled. For example, we should build strong houses and buildings that are quake-proof. Language ...
Otherwise, it may result in failed eruption forecasts either because eruption does not occur or because it does not correspond with the expected size (e.g.: La Sufriere Guadeloupe, 1976; Akutan, Alaska, 1996; Tungurahua, Ecuador, 1999; Paricutin, Mexico, 2006; Fourpeaked, Alaska, 2006; ...
spatio-temporal correlation between seismic and volcanic events does not necessarily imply a causal relationship. Two concurrent events could result from a common third underlying process, or occur by chance. Yet observing a correlation is a necessary first step in unravelling a potential causal ...
