Designed for students with a reading age of 8 and 9 years old, this colourful non-fiction title looks at extreme, dangerous, or problematic aspects of the shaping of the Earth's surface such as erosion, earthquakes, volcanoes, and wild f... SF Staples - 《Macmillan》 被引量: 0发表: 0...
(Lovers of geographical trivia should note that, despite their names, the summits of both volcanoes are actually located in the state of Jalisco, not in the state of Colima.) Colima Volcano is considered one of Mexico’s most dangerous volcanoes. Numerous villages in its shadow keep a wary ...

Given this history, Volcan Baru will erupt again, following some premonitory period of seismic activity and subtle ground deformation that may last for days or months. Future eruptions will likely be similar to past eruptions explosive and dangerous to those living on the volcanos flanks. Outlying...
rocks, ash and superheated gases that rapidly flow down from the area of dome collapse on a volcano. Pyroclastic surges are similar, but less dense. They are a kind of hot ash hurricane that can escape the confines of river valleys. Both types of currents are dangerous and frequently lethal...
Debris flows are fast-moving landslides that occur in a wide variety of environments throughout the world. They are particularly dangerous to life and property because they move quickly, destroy objects in their paths, and often strike without warning. U.S. Geological Survey (USGS) scientists are...
Lahars are rapid flows of mud–rock slurries that can occur without warning and catastrophically impact areas more than 100 km downstream of source volcanoes. Strategies to mitigate the potential for damage or loss from lahars fall into four basic catego
