HAWAII VOLCANOES NATIONAL PARK – A large lava spillover this morning at the summit of Kilauea volcano enlarged the area of the overflow surrounding the active lava lake.

According to the USGS Hawaiian Volcano Observatory:

The lava lake level has been at, or near, the rim of the Overlook crater over the past day. The lake overflowed onto the floor of Halemaʻumaʻu Crater several times over the past day, with the largest overflow occurring around 2 am this morning. This 2 am event enlarged the area of overflows surrounding the active lava lake. Yesterday afternoon the lava lake level was measured at roughly 4 meters (yards) above the original (pre-overflow) floor of Halemaʻumaʻu Crater. The recent overflows have accumulated and built the rim of the Overlook crater up several meters (yards) above the original floor of Halemaʻumaʻu Crater. This morning, the lava level remains close to the rim of the Overlook crater.USGS Hawaiian Volcano Observatory on May 2 at 8:46 a.m.

Scientists say seismicity is elevated beneath Kīlauea’s upper East and Southwest Rift Zones. Sulfur dioxide emission rates averaged 4400-5400 tonnes/day for the week ending April 28.
