Evacuation zone ‘still dangerous’ as eruption could happen with only minutes’ notice, warns civil defence official
Land swelling is common prior to volcanic eruptions, and Professor Thorvaldur Thordarson said the ground is now rising some 5.5 times faster than it did 10 days ago, with the flow of magma into ...
The volcanic activity that results as the Indo-Australian plate subducts the Eurasian plate has created the Sunda Arc. As well as the sideways movement between the plates, the 2004 Indian Ocean earthquake resulted in a rise of the seafloor by several metres, displacing an estimated 30 km 3 (7.2 cu mi) of water and triggering devastating tsunami ...
