LA PALMA, Spain, Oct 17 (Reuters) - There is no immediate end in sight to the volcanic eruption that has caused chaos on the Spanish isle of La Palma since it began about a month ago, the president of the Canary Islands said on Sunday. There were 42 seismic tremors on the island on Sunday, the largest of which measured 4.3, according to the Spanish National Geographical Institute.

Streams of lava have laid waste to more than 742 hectares (1,833 acres) of land and destroyed almost 2,000 buildings on La Palma since the volcano started erupting on Sept. 19. About 7,000 people have been evacuated from their homes on the island, which has about 83,000 inhabitants and forms part of the Canary Islands archipelago off northwestern Africa. All of the 38 flights which were scheduled to arrive or take off from La Palma airport on Sunday were cancelled because of ash from the volcano, state airport operator Aena said, but the airport there remains open.
