Roadblocks, subdivisions, and eruption fissures
Hawaiian Volcano Observatory daily update
The eruption of lava continues from multiple points along the northeast end of the active fissure system. Residents in lower Puna should remain informed and heed Hawaii County Civil Defense closures, warnings, and messages (www.hawaiicounty.gov/active-al…)
This morning, activity is dominated by lava fountaining, explosion of spatter more than 100 feet into the air, and an advancing lava flow from fissure 17 at the northeast end of the fissure system. As of 6:30 a.m. the fissure 17 flow had traveled just under a mile roughly east-southeast parallel to the rift zone. It is turning slightly south and at this time is about one-half mile south of Highway 132.
Fissure 18 that became active late yesterday is weakly active.
A fissure 19 has been spotted very near fissure 15 as of about 8 a.m. just northeast of Pohoiki Road and north of Hinalo Street at the east end of Lanipuna Gardens. It is producing a sluggish lava flow.
Volcanic gas emissions remain elevated throughout the area downwind of the vents. Yesterday with the onset of activity at fissure 17, powerful steam jets have occurred intermittently near the west end of the fissure. These jets may be responsible for some of the loud sounds reported by residents and emergency workers.
HVO field crews are on site tracking the lava flow as conditions allow and reporting information to Hawaii County Civil Defense.
This eruption is still evolving, and additional outbreaks of lava are possible. Ground deformation continues, and seismicity remains elevated in the area.
The location of future outbreaks could include areas both uprift (southwest) and downrift (northeast) of the existing fissures, or, existing fissures can be reactivated. Communities downslope of these fissures could be at risk from lava inundation. Activity can change rapidly.
Conditions around the erupting fissures can change very quickly.Residents in lower Puna should remain informed and heed Hawaii County Civil Defense closures, warnings, and messages (www.hawaiicounty.gov/active-al…).
