Pu'u O'o inflation

Wow, I wonder what will happen.

I now wonder if an eruption has begun at all. Unlike the way I imagined it would have unfolded all the signs I pointed to earlier have calmed down a bit and the summit has yet to show any signs of the lake dropping.

Whatever it is I think it's great to have all the data HVO shares with the public and to be able to watch and speculate on what might be happening.

When I used to work up at KVC we had a little box with a big red button that said “press button for eruption” that we would take out whenever tourists asked where they could see lava.

Clearly you guys need to go up to KVC and ask to press the button.

Pele is clearly making a statement for May Day 2018. The swarm continues 15 in the last hour. Webcams don't show much yet but deformation clearly has changed big time before midnight.

2:39AM Just felt a 4.0, near sea arch 5 miles deep.

Area: Hawaii

Volcanic Activity Summary: Summary:

A collapse of the Pu#699;u #699;#332;#699;#333; crater floor Monday afternoon on K#299;lauea Volcano's East Rift Zone has prompted increases in seismicity and deformation along a large section of the rift zone, with seismicity currently occurring as far east as Hwy 130. A outbreak of lava in a new location is one possible outcome. At this time it is not possible to say with certainty if or where such an outbreak may occur, but the area downrift (east) of Pu#699;u #699;#332;#699;#333; is the most likely location, as this is where seismicity and deformation have been concentrated overnight.

Residents of lower Puna should remain alert and watch for further information about the status of the volcano; watch for Hawaii County Civil Defense messages at http://www.hawaiicounty.gov/active-alerts

Recent Observations:

Between about 2:00 and 4:30 pm on Monday, April 30, following weeks of uplift and increasing lava levels within the cone, the crater floor at Pu'u '#332;'#333; on K#299;lauea Volcano's East Rift Zone collapsed.

Poor weather prevented HVO from flying over the activity or seeing details of the activity in our web cameras on site.

Following the collapse, HVO seismometers and tiltmeters recorded an increase in seismic activity and deformation from K#299;lauea Volcano's summit to an area about 6-10 miles downrift (east) of Pu#699;u #699;#332;#699;#333;. Overnight, this activity localized downrift of Pu#699;u #699;#332;#699;#333; and continued to propagate eastward along the rift zone.

The largest earthquake of this sequence so far was a magnitude 4.0 earthquake just offshore south of Pu'u '#332;'#333; at 02:39 this morning,

K#299;lauea's summit eruption has thus far not been affected by the change at Pu'u '#332;'#333;.

Hazard Analysis:

The migration of seismicity and deformation downrift (east) of Pu#699;u #699;#332;#699;#333; cone following Monday's collapse indicates that a large area along the East Rift Zone is potentially at risk for a new outbreak.

The location of any future outbreak will determine what areas are in the path of new lava flows.

The situation is rapidly evolving and USGS Hawaiian Volcano Observatory scientists continue to closely monitor K#299;lauea's East Rift Zone and summit. More updates will follow as information becomes available.

Pu’u O’o oh oh!

Looking at the earthquake map - -
most of the quakes since yesterday are centered around the Chain of Craters Road area which is closed to traffic, west Kalapana Gardens. Civil Defense describes the location as between Pu'u O'o and Highway 130.

The information above comes from HVO, not Civil Defense.

Yes. Civil Defense also sent out an active alert at 6 AM this morning with the location of: "increased earthquake activity in lower Puna between Puu Oo and Highway 130."

Highway 130 went to the entrance of the National Park.The latest earthquakes are east of that road.

latest earthquakes are east of that road.

Headed out to sea in the Kapoho direction? If it continues, and there's a fissure, you might have front row seats Obie?

As of 9:30 AM Dept of Parks & Rec shut down the Kalapana Lava Viewing area due to the earthquakes.
