Activity at Kilauea Volcano continues to wind down

Advertiser Staff

After a flurry of earthquakes a week ago' and the subsequent outpouring of lava at a new location, activity at Kilauea Volcano on the Big Island continues on a downward trend, scientists at the Hawaiian Volcano Observatory said yesterday.

According to the latest update issued by the observatory at 8:45 a.m. Saturday:

Pu`u `O`o activity is paused. There is no active lava visible anywhere on the flow field. A tiltmeter at Pu`u `O`o continues to show steady tilting inward toward the crater indicating that collapse of the crater floor is continuing. Tilting of the north side of the cone has totaled about 100 microradians since Sunday, June 17. Seismic tremor values and sulfur dioxide emissions from Pu`u `O`o have dropped to well below pre June 17 levels, consistent with the shutdown of the vent.

There is no new activity at the site of the June 18/19 eruption. The crack west of Kane Nui o Hamo continues to emit steam and fume. Sulfur dioxide emissions from this crack have been declining. Seismic tremor levels in this area have declined to pre June 17 values. Very few earthquakes were recorded since 12 a.m. Saturday; none were large enough to locate.

The summit area continues to inflate very slowly. Seismic the tremor levels continue to decline toward pre June17 levels. Very few earthquakes were recorded since 12 a.m. Saturday. None were large enough to locate. Sulfur dioxide emissions and concentration levels are elevated but also continue to decline.
