UPDATE...............What's Going On With the Volcano?

Current Conditions Courtesy USGS - Hawaiian Volcano Observatory

Tuesday, December 18, 2018, 2:13 PM HST

Activity Summary: Kīlauea Volcano is not erupting. Rates of seismicity, deformation, and gas release have not changed significantly over the past week. Deformation signals are consistent with refilling of the middle East Rift Zone.

Observations: HVO monitoring during the past week showed no significant changes. Low rates of seismicity at the summit and East Rift Zone (ERZ) continue, with events occurring primarily at Kīlauea's summit and Kīlauea's south flank areas, totaling around 220 detected earthquakes in those areas since last check. In the ERZ, tiltmeters showed little change over the last week, with GPS indicating minor inflation downrift from Puʻu ʻŌʻō. Sulfur dioxide emission rates have been below detection limits in the LERZ since early September, though minor amounts of volcanic gas are still present. Sulfur dioxide emission rates were last measured at ~35 t/d at both the summit and ERZ, consistent with the past few months of emissions from Kīlauea.Hazards are still present in the LERZ eruption area and at the Kīlauea summit. Residents and visitors near recently active fissures and lava flows should stay informed, heed Hawaii County Civil Defense and National Park warnings, and be prepared, if necessary, to self-evacuate in the unlikely event of renewed activity. Please note that Hawaii County maintains a closure of the entire flow field and the vents and prohibits access to the area unless authorized through Civil Defense.

The Hawaiian Volcano Observatory (HVO) continues to closely monitor Kīlauea's seismicity, deformation, and gas emissions for any sign of reactivation, and maintains visual surveillance of the summit and the East Rift Zone. HVO will continue to issue a weekly update (every Tuesday) and additional messages as warranted by changing activity.

1. Wow... was there just a couple weeks ago...

the national park is amazing. But, it does give one pause, in case something blows.
