The world was captivated by the eruptions of several major volcanos in 2010. In Iceland, two spectacular explosions in March and April sent huge plumes of ash and smoke high into the atmosphere, causing European air traffic to come to a standstill — the most serious delays the region had seen since World War II.
Then, in Indonesia in November, Mount Merapi, the country's most-volatile volcano, erupted. It forced the evacuation of thousands of villagers from its slope and ultimately killed more than 100 people, including Mbah Maridjan, the celebrated spiritual gatekeeper of the mountain.
