Earthquakes and Volcanoes

Three people have been killed and 45 hurt after two powerful earthquakes shook eastern Indonesia. The quakes, of magnitude 6.4 and 5.0, hit within hours of each other.
Hundreds of buildings were damaged or destroyed. Witnesses said many residents had fled their homes and were unwilling to return. Can you think why?
The country lies on the Pacific Ring of Fire, one of the most active regions of the world for earthquakes and volcanoes. Most of the injured were said to have been hit by collapsing walls.
The tremors caused a power cut, forcing a hospital to be evacuated briefly.
Indonesia was the nation worst hit by the Asian tsunami in December 2004, which killed 168,000 people.
Nice wee video here on sea floor spreading at the Atlantic ridge.

Another one her of Old Faithful geyser - Yellowstone National Park

Iceland’s eruption of Heimaey (forgive the awful American pronunciation if this volcano) The rest is good

And also this one from the National Geographic channel
