Kilauea, Hawai : presence of an active lava pond on the east rim of Pu’u ‘O’o crater.

Kilauea, Hawai : presence of an active lava pond on the east rim of Pu’u ‘O’o crater.

Activity Summary:
Eruptions continue at Kilauea Volcano’s summit and East Rift Zone. Seismic activity and deformation rates throughout the volcano are within background levels. Field observations near Pu’u ‘O’o yesterday confirmed lava ponds both within and on the east rim of the crater. Scattered lava flow activity continues on the June 27th lava flow field within about 6 km (4 mi) northeast of Pu’u ‘O’o, but currently poses no threat to nearby communities.

Summit Observations:
The lava lake remains active and circulating within Halema’uma’u Overlook crater. Seismic tremor levels have been variable but within background values. Tilt has leveled off in the past day, after accumulating about 3 microradians of inflationary tilt since Monday. The lava lake level has fluctuated slightly throughout the past day, but the average level remained about 38 m (125 ft) below the Halema’uma’u crater floor. Summit sulfur dioxide 24-hr average emission rates ranged from 1700-2700 metric tons/day when last measured on December 9 and 10.

Pu’u ‘O’o Observations:
Field work yesterday confirmed the presence of an active lava pond on the east rim of Pu’u ‘O’o crater, where webcam images have been showing an incandescent, fuming source, in addition to the usual persistent glow sources within the crater. Seismic activity remains low. Pu’u ‘O’o tiltmeters recorded no significant tilt. The sulfur dioxide emission rate from all East Rift Zone vents was about 280 metric tons/day when it was last able to measured, on November 30.

June 27th Lava Flow Observations:
A helicopter overflight yesterday confirmed continued activity within the Pu’u ‘O’o flow field. Active flows are scattered within about 6 km (4 mi) of Pu’u ‘O’o and are not threatening any nearby communities.
