Hazardous Living: Thirty years after Mount St. Helens exploded

Thirty years ago today, sometime not long after 8:30 a.m. Pacific time, Mount St. Helens explosively erupted. The shock wave from the eruption washed over Oregon and Washington, shaking the ground up to 400 kilometers away. Two earthquakes followed, at 8:32 and 8:34 a.m. Shortly thereafter, with a tremendous burst, the upper north flank gave way as gas, steam and ash vented outward and sent out an immense landslide of hot rock, mud, water, ash and debris.

Tracking volcanic ash: Helping airplanes avoid catastrophe

For more than 9,000 years, Chaitén volcano quietly towered 1,122 meters over southern Chile. The volcano seemed almost asleep: Its wide crater, shaped by layers of ash and pumice from an ancient eruption, held two lakes and a giant dome of obsidian — the same glossy black rock that was used in prehistoric times to shape artifacts found at archaeological sites as far as 400 kilometers away. Almost at the foot of the volcano, just 10 kilometers to the southwest, a small village grew into the town of Chaitén, population 4,200.

Getting a master's in social geology

At first glance, it seems like an obvious solution to a problem: Villagers need vegetables and an aid organization has money to buy tools and seeds. Striving to create a sustainable program, the aid organization develops a training plan to teach the villagers how to garden, invests in local workshops, and purchases tools to distribute to the participants. All plans seem in order and the project is poised for success. However, the project’s managers encounter the first of potentially many obstacles when they realize that shovels are impossible to use if you don’t have shoes.
