Kīlauea Volcano — Collapse and Dust Rising at Halema`uma`u Crater

At 1:20 PM HST on July 5, a collapse explosion event occurred at Kīlauea's summit. The energy released by the event was equivalent to a M5.2 earthquake. The shaking

Kīlauea Volcano — Lavafall Near Kapoho Crater

Near the Kapoho Crater, in the area called Four Corners, the lava channel makes a 90-degree bend. After lava exits the bend, it makes a short drop to form a lavafall. A side channel makes a short surface diversion before rejoining the existing channel.

July 5, 2018, collapse event at Kīlauea Volcano's summit

Since August 4, 2018, Kīlauea Volcano's summit activity has diminished dramatically. But between mid-May and early August, 62 collapse events occurred, with each releasing energy equivalent to a magnitude-5+ earthquake and causing extensive ground shaking in the summit area. On July 5, 2018, USGS video cameras stationed at various summit locations happened to record one of

Kīlauea Volcano — Lava Channel Bend

The lava channel from fissure 8 jumped its banks near Kapoho Crater where the channel makes a 90 degree bend. The flow within the channel was diverted around a constricted area and joined the channel again "downstream" to the south (left).

830-year-old explosion deposit
April 12, 2018

Three deposits from explosive eruptions at the summit of Mauna Loa are located west, northwest, and east of Moku‘āweoweo, the volcano's summit caldera. In map view, these deposits are fan-shaped. Along the ‘Āinapō Trail, 2.8 to 3.5 km (1.7 to 2.2 mi) southeast of the caldera, several kīpuka expose a fourth distinct explosive deposit.

Degraded coral reefs at Kahekili Beach Park, west Maui, Hawai‘i.
March 30, 2018

According to a study by USGS scientists, polluted, low-pH groundwater discharging onto a shallow coral reef off Kahekili Beach Park in west Maui, Hawai‘i, further increases seawater acidity and exposes corals to nitrate concentrations 50 times higher than normal.
