After months of pre-eruptive activity, Alaska's Mount Redoubt has erupted 6 times since Sunday night. Telegraphing its eruption with massive shallow earthquake activity in the range of 26 earthquakes every 10 minutes, the volcano, located around 100 miles southwest of Anchorage, spewed an ash column 10km high, and is expected to continue erupting for weeks or months. The last time this massive volcano erupted in 1989 a commercial airliner was caught in the ash column, causing the engines to seize and the plane to lose two miles of altitude before the engines were restarted. That eruption, which lasted for 5 months, produced this spectacular photo. Follow this amazing event at the Alaska Volcano Observatory. [more inside]
