Time-lapse movie of Kilauea’s Lower East Rift Zone in Puna. This image is from a temporary research camera positioned near Kapoho looking southwest. One can see the eruptive Fissure 8 near the center. July 24-31, 2018. Images courtesy of USGS/HVO
Map as of 1:00 p.m. HST, July 31, 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 Tuesday, July 31. The fountain at Fissure 8 remains active, with the lava flow entering the ocean. The dominant ocean entry points were on the section of coastline near Ahalanui. The black and white area is the extent of the thermal map. 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. The base is a copyrighted color satellite image (used with permission) provided by Digital Globe.
This is a Civil Defense Message for 4 p.m., Tuesday, July 31, 2018.
The Hawaiian Volcano Observatory reports that earthquakes continue at Kilauea summit and fissure 8 continues to erupt lava into the perched channel, sending flows to the ocean at Ahalanui and creating a large laze plume. No overflows were reported this morning. The margin of the flow at the ocean entry has not advanced and remains approximately 500 feet from the Pohoiki boat ramp.
State Highways reports no new cracks on Highway 11 after the 8:00 am collapse event at Halemaumau crater. Between mile marker 28 and 32, motorists are advised to stay on the pavement, be alert for changing roadway conditions, and drive with caution. Motorcyclists and bicyclists should proceed with extreme caution.
The next Kilauea eruption community meeting at Pahoa High School cafeteria tonight, July 31 at 5 p.m. will feature a shortened set agenda, to allow more time for questions and answers.
The following guidelines remain in effect:
Check all utility connections of water, gas, and electricity for potential damage from earthquake activity.
Do not access the active flow field due to extreme hazard. Be aware that channel overflows and other breakouts are possible on the active flow field.
The ocean entry continues to produce a laze plume. Take precautions and stay out of the plume to avoid exposure to hydrochloric acid and glass particles, which can irritate the skin, eyes, and lungs.
Disaster assistance is available island-wide to individuals and businesses in Hawaii County that have been affected by the Kilauea eruption.
The Disaster Recovery Center has moved and is now at the Pahoa Community Center, located at 15-3016 Kauhale St., Pahoa. Hours of operation are 8 a.m. to 6 p.m. weekdays and 8 a.m. to 4 p.m. on Saturdays.
Access placards are available at the Civil Defense office located at 920 Ululani Street in Hilo.
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.
Ocean entry laze
Due to the lava entry at the ocean, the following policies are in effect:
Access to the area is prohibited due to the laze hazard.
Stay away from any ocean plume since it can change direction without warning.
The U.S. Coast Guard is actively monitoring the ocean entry area and enforcing a 300-meter standoff zone. Only permitted tour boats are allowed in the area.
Health hazards of laze include lung, eye and skin irritation.
Be aware that the laze plume travels with the wind and can change direction without warning.
