The same volcanic eruptions that sundered Greenland from Western Europe and created Iceland also triggered intense global warming 55 million years ago, scientists say.

On March 29, the Shiveluch Volcano on the Kamchatka Peninsula erupted, sending an ash cloud skyward roughly 32,000 feet. Satellites often capture images of volcanic ash plumes, but usually as the plumes are blowing away. This image, however, is different. It shows the gray-brown ash cloud suspended directly over the summit. [via warren ellis]

Predicting volcano eruptions has always been more black art than science. No one really knows what's happening beneath the surface--until it's too late. That could soon change. Armed with a network of sensors, a team of researchers has used computed tomography scanning to probe the interior of Mount Etna before, during, and after an explosion.
