Shake and Pour: Hawaii Lava Spills into Ocean

  
Lava from Kilauea volcano in Hawaii drops into the ocean. Steam plumes rise where the hot molten rock meets the sea.

More than 30 small earthquakes, most too small to feel, shook the island of Hawaii in the past two weeks.

The tremors are signs of magma moving underground, feeding two ongoing eruptions at Kilauea volcano.

A sticky, slow-moving stream of lava called pahoehoe is crossing the coastal plain east of Hawaii Volcanoes National Park, dripping into the ocean and creating a delta. The lava flow is 0.6 miles (1 kilometer) wide, according to a statement from the U.S Geological Survey's Hawaii Volcano Observatory. The delta has grown 165 feet (50 meters) in width since Nov. 24, the USGS reports.
