Volcanoes in Hawaii, Alaska: Science and Tourism

"Hawaii Volcano Glows"
LiveScience (June 7, 2009)

"Lava is thought to be close to the surface of the summit of Hawaii's Kilauea volcano, suggesting a modest eruption might occur. But geologists don't really know if it will erupt, or if lava might simply flow from the summit, or neither.

"In past events, the volcano's lava has sometimes travelled 6 miles (10 kilometers) from the crater to the sea. The flows, at 2,100 degrees Fahrenheit, occasionally explode when they contact the cool ocean waters...."

The glow-in-the-dark volcano got a more extensive writeup in The Associated Press:

That photo, from the LiveScience article, shows that there are places that have more trouble with road maintenance than Minnesota.
LiveScience also has a somewhat more detailed article about the use of a Lightning Mapping Array at Alaska's Mount Redoubt volcano:
