If lava flows or ash spews somewhere on Earth, the crew at Volcano World takes note. Hosted by the University of North Dakota in Grand Forks, the site posts weekly updates that describe current eruptions and lets you zoom in on the location using the mapping program Google Earth. You can also peruse a catalog that supplies charts, photos, and records of past activity for volcanoes such as Rabaul in the South Pacific. The ash plume from its 1994 eruption ascended more than 18 kilometers. To learn more about volcanism, flip through the FAQ section. Volcano World's experts answer more than 1000 reader queries on everything from the relation between lava color and temperature (yellow is hotter than red) to the effect of Krakatau's 1883 explosion on global climate. (The ash it ejected caused a one-quarter-degree cooling that lasted up to 2 years.) Or for a little lava tourism, follow the Volcano of the Week feature to an interesting peak.
