Kīlauea Volcano — Kapoho Bay and Vacationland

Lava from fissure 8 travels about 13 km (8 mi) down a well established channel (visible in the center of the image) to an ocean entry at Kapoho. Lava is building a seaward delta that is approximately 320 acres in size. The view is to the southwest with the Kapoho area in the lower right. The white

Fissure activity and active ocean entry in Kīlauea's LERZ

Fissure 8 produces a lava fountain that pulses to heights of 55 to 60 m (185 to 200 ft). Spattering has built a cinder cone that partially encircles fissure 8, now 51 m (170 ft) tall at its highest point. The steam in the foreground is the result of heavy morning rain falling on warm (not hot) tephra (lava fragments).

Kīlauea Volcano — Vacationland Ocean Entry

View of the active ocean entry in the vicinity of Vacationland. The interaction of hot 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, but that dissipates quickly with distance.

Kīlauea Volcano — Halema`uma`u Slumping

At Kīlauea Volcano's summit, inward slumping of the rim and walls of Halema‘uma‘u continues in response to ongoing subsidence. In this view to the southwest taken after this morning's event, a section of dark-colored wall rock (center left) has detached and dropped downward into the crater.

seismologists install a nodal geophone on Kīlauea's lower East Rift Zo

University of Utah seismologists install a nodal geophone on Kīlauea's lower East Rift Zone in June 2018. This instrument was part of a network of 82 seismometers deployed temporarily this summer to help scientists study the magma transport system beneath the volcano's eruption sites.

April 20, 2017

In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai’i, U.S. Geological Survey researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.
