The intrusive activity that began on 23 August continues south of Kilauea caldera.
The Hawaiian Volcano Observatory (HVO) reported that ground deformation in Kilauea's south summit region continues, though at a rate slightly lower than the rates seen in the first intrusive pulse spanning August 23-25. The rate of ground deformation beneath the south part of Kilauea summit region, within Hawaiʻi Volcanoes National Park, decreased slightly in the evening of 28 August.
The seismic activity continues at reduced levels compared to the earlier pulses of this intrusive activity. The seismic station recorded approx. 95 volcano-tectonic earthquakes at volcano summit and south of the caldera over the past 24 hours. Most of the earthquakes were less than magnitude 2 and occurred approximately 1-4 km (0.6-2.5 mi) below the surface.
New magma has accumulated under the caldera and there is still an increased possibility that it might lead up to an eruption in a near future.
Volcano Alert Level and Aviation Color Code remain at Advisory/Yellow.
