Kilauea Eruption Update

Map as of 2:00 p.m. HST, August 6, 2018. Given the dynamic nature of Kīlauea’s lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

This thermal map shows the fissure system and lava flows as of 6 am on Monday, August 6. Fissure 8 activity has decreased substantially over the past few days, with only a weak lava pond active within the Fissure 8 cone. There were no signs on the surface of lava being supplied from the vent into the channel. Nevertheless, residual lava in the flow continues to enter the ocean, mainly around Ahalanui. The black and white area is the extent of the thermal map. The temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.

This is a Civil Defense Message for 7:30 a.m., Tuesday, August 7, 2018.

The Hawaiian Volcano Observatory reports that eruptive activity has decreased at the Kilauea summit and lower east rift eruption from fissure 8. Seismic activity is low with few felt earthquakes at the summit. Crews overnight in the lower east rift report only glow in fissure 8. HVO continues to monitor Kilauea for signs of reactivation of activity. Several overflights are scheduled throughout the day to visually monitor the volcano.

The following guidelines remain in effect:

Disaster assistance is available island-wide to individuals and businesses in Hawaii County that have been affected by the Kilauea eruption.

The Pahoa Post Office is open during normal business hours with temporary Sunday hours from 10 a.m. to 2 p.m. for mail and package distribution only for residents in the affected areas. Mail delivery has resumed for areas where roadways have reopened. No retail services on Sunday.

For your safety, heed warnings from Civil Defense officials and stay alert.

Volcanic gas emissions remain elevated throughout the area downwind of the vents in lower Puna.

County, State, and Federal partners continue to monitor the situation. You will be informed of any conditions that affect your safety.

Monitor vog levels and forecasts: People on Hawaii Island outside the area of volcanic activity are also advised to monitor levels of vog at vog.ivhhn.org

The residents of Puna are going through a very difficult time. We ask for your help and understanding.
