LA PALMA, Spain (Reuters) -Blocks of molten lava as large as three-storey buildings rolled down a hillside on the Spanish island of La Palma on Sunday while a series of tremors shook the ground three weeks after the volcano erupted.

There were 21 seismic movements on Sunday, with the largest measuring 3.8, the Spanish National Geological Institute (ING) said, shaking the ground in the villages of Mazo, Fuencaliente and El Paso.
