About 600 homes have been destroyed by the multiple lava flows that were produced during this lower East Rift Zone eruption, in the Leilani Estates during the early days of the eruption and lately in Kapoho and Vacationaland. The large lava delta that has been created outside former Kapoho Bay is about 1.9 (1.2 mi) wide, creating multiple vigorously steaming lava ocean entries as well as upwelling of a large offshore area where lava is actively flowing onto the ocean floor. HVO/USGS warn that the lava delta is unstable because it is built on unconsolidated lava fragments and sand, loose material that can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. Additionally, the interaction of lava with the ocean creates "laze", a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Over the past week a cycle emerged in the seismicity monitored at Kilauea’s summit area, where increasingly larger and more frequent earthquakes culminated in a magnitude 5 earthquake. These earthquakes are usually accompanied by an explosion and ash cloud from Halema’uma’u crater and followed by a short period of less earthquakes before seismicity picks up again, building towards the next larger earthquake and explosion. The last two of these larger earthquakes were a M5.6 earthquake on Wednesday afternoon 6 June at 16h07 and a M5.2 earthquake on early Friday morning 8 June at 02h44. In each case there was also a small explosion at Halema’uma’u crater creating an ash plume that rose up to about 3050 meters (10,000 feet). Each time summit seismicity dropped significantly right after the earthquake and explosion, but then picked up again a few hours later and gradually increased until the next larger event.
On June 5, 2018, a HVO scientist who has been studying the changes of Kilauea’s summit caldera for decades briefly visited the parking area for the former Halema‘uma‘u overlook (closed since the re-appearance of a lava lake in 2008) to make direct observations of and gather data from the effects of recent explosions within Halema‘uma‘u. HVO reports that the parking lot is strewn with small ballistic blocks, most of them only a few centimetres across but some larger blocks reaching up to 45 cm (18 inches) in diameter. Many of these larger blocks appeared to be in depressions in the ash, but upon closer examination, it was concluded that wind had winnowed ash from around the blocks, creating a false impression that the depressions were made by impact. Apart from ballistic blocks and an ash layer up to 4 cm (1,5 inch) thick, the Halema‘uma‘u parking lot is sliced into blocks by cracks which were first noted in a very early stage on May 13 but are now dominant. These cracks are circumferential to Halema‘uma‘u and warp and offset the pavement and curbing of the parking lot. Cracks have varying sizes, an average one for example shows 42 cm (16.5 in) of right lateral offset—as measured by fitting the center stripe on the road back together—and was about 25 cm (10 in) wide.

The activity in the lower east rift zone continues with no significant changes. After a brief episode of declining output of magma from fissure #8 and the contemporary reactivation and lava effusion from a number of other fissures, activity shifted back to fissure #8 which has been the main vent of the rift eruption over the past week. ...more [read all]
