Can we spot volcanoes on alien worlds? Astronomers say yes

Now that astronomers are finding rocky worlds orbiting distant stars, they're asking the next logical questions: Do any of those worlds have volcanoes? And if so, could we detect them? Work by theorists at the Harvard-Smithsonian Center for Astrophysics suggests that the answer to the latter is a qualified "Yes."

Icelandic volcanic activity could be influenced by thinning ice caps

The thinning of Iceland’s ice caps could be influencing volcanic activity, according to new research. The study developed a model to predict the changes in pressure on magma caused by thinning ice and applied it to the recent activity of two Icelandic volcanoes. The results suggest that the effects of thinning ice may increase volcanic activity in some cases, but reduce it in others.
