Inflationary tilt that began on Wednesday continues to be recorded by tiltmeters at the summit of Kilauea.

In correspondence with the inflation, the lava lake within the Overlook crater has begun to rise steadily, according to Hawaiian Volcano Observatory, although an exact lava rise level was not immediately available.

For the week ending on July 28, HVO reports that Kilauea summit sulfur dioxide emission rates ranged from 2,600 to 5,500 metric tons per day.

Seismicity has also continued at background levels, both below Kilauea’s summit and at Puʻu ʻŌʻō.

No changes were noted at Puʻu ʻŌʻō as tiltmeters at the crater have not recorded any significant change in activity in recent weeks.


As of the last measurement of sulfur dioxide at the Puʻu ʻŌʻō vent on July 23, about 500 tonnes per day were measured as the vent’s emission rate.
Webcam and satellite imagery continue to assist in June 27, 2014 lava flow monitoring. HVO geologists observing the flow have noted that it remains about 2.5 to 5 miles to the northeast of Puʻu ʻŌʻō.
