La Palma lava flows
La Palma is a basaltic shield volcano in the Canary Islands. Like Hawaiian volcanoes, La Palma typically erupts lava flows. This aerial photo, courtesy of Radio Televisión Canaria, shows lava flows that are being generated by a fissure eruption upslope on La Palma. One of the lava flows is entering the ocean, creating new land called a lava delta. Lava deltas are built by the accumulation of lava near the base of the sea cliff at an ocean entry.
