Kilauea Summit Update – 8/20/15
Kilauea continues to inflate as tiltmeters at the summit record inflationary tilt for the second day in a row.
The lava lake within the Overlook crater continues to inflate as seismic tremor continues with episodic bursts that are associated with spattering.
Hawaiian Volcano Observatory reports that when last checked on Wednesday, the surface of the lava lake was about 67 meters below the floor of Halema`uma`u.
Sulfur dioxide emission rates at the summit ranged from 2,000 to 2,200 metric tons per day for the week ending on Aug. 15, according to HVO.
Seismic activity within Kilauea and at Puʻu ʻŌʻō remain at low levels.
Puʻu ʻŌʻō has not seen any changes in activity over the past day as the persistent incandescent crater vents remain in the crater.
As of Aug. 13, the sulfur dioxide emission rate from all East Rift Zone vents was measured at about 390 tons per day.
The June 27, 2014 lava flow continues to remain active on the flow field. Surface flows are scattered in three areas to the northeast and east of Puʻu ʻŌʻō and are all 5 miles from the area.
