Watch: Kilauea volcano's Lava Lake Overflowing For The First Time In 30 Years [Video]

For the first time in 30 years, the floor of Halema'uma'u crater saw lava flowing. Overnight, the volcano's volatile lava lake spilled over the rim of deep vent with within Halema'uma'u crater several times.

"The lava lake level has been at or near the rim of the Overlook crater over the past day. At 9:40 pm last night, a very small, brief overflow occurred onto the floor of Halemaʻumaʻu Crater. A larger overflow occurred at 2am this morning, sending lava a short distance onto the floor of Halemaʻumaʻu Crater, and another overflow is occurring this morning around 8am," USGS Hawaiian Volcano Observatory said on Wednesday.

The spillover is the latest in a series of volcanic events connected to a rise in the level of the lava lake that began last week in conjunction with an increase in inflation measured at the summit. This is the highest the lava lake has been since the eruption began in March 2008, BIVN noted.

Experts said the crater's position poses no risk to people or structures.
