HILO, Hawaii (AP) 鈥� One of the world鈥檚 most active volcanoes, on Hawaii鈥檚 Big Island, began spewing lava from the north vent Wednesday, the latest event in an ongoing eruption that began almost six months ago.
Lava fountains reached heights of more than 330 feet (100 meters) and feeding multiple lava streams. Scientists with the U.S. Geological Survey鈥檚 Hawaiian Volcano Observatory said the fountains were likely to go higher.
The latest event was preceded by gas-pistoning, in which gas accumulates at a lava column's top within a vent, on Tuesday.
The observatory said this process causes the lava surface to rise or piston. 鈥淓ventually, gas escapes as splatter/lava is erupted, and lave drains back into the vent,鈥� the observatory wrote on its Facebook page.
These were occurring up to 10 times an hour, but increased in intensity until a small, sustained dome fountain began to feed flows to the crater floor a day later.
It is the 25th eruptive episode since the volcano on the southeastern part of the island . It has been pausing and resuming since.
Most of the eruptive episodes have spewed lava for about a day or less, with pauses between them generally lasting a few days.
