Earthquakes (red dots) track the progression of the magmatic intrusion from Kīlauea Volcano's middle East Rift Zone to the lower East Rift Zone between April 30 and May 3, 2018. Orange triangles show the locations of fissure 1 (right), which erupted on May 3, and Pu‘u ‘Ō‘ō (left).

“The ocean is the closest I can get to an unexplored world, without going into space... I mean, I feel a deep connection to the ocean and its constant rhythms, but when I visit, there's a new discovery or appreciation every time.

Coastal Change Storm Hazard Team map created Tuesday, 10/89/18 showing current forecasted beach erosion, overwash and inundation effects of Hurricane Michael's predicted landfall in the Florida Panhandle. Forecast will change with subsequent National Hurricane Center forecasts.

This thermal map was constructed by merging about 1300 images from a morning helicopter overflight, and shows the distribution of some of the prominent thermal features in the caldera. The most conspicuous area is a region of high temperatures in the deepest part of the collapse depression, in the area of Halema‘uma‘u.

Only small amounts of sulfur dioxide (SO2) and hydrogen sulfide (H2S) are currently being released from Kīlauea, but they chemically react with each other (oxidation-reduction reaction) to form the bright yellow sulfur deposits visible on the crater walls within Halema‘uma‘u.

A scientist takes a gravity reading at a station located on the down-dropped block of Kīlauea caldera, which subsided as an intact structure, while a second gravity instrument (foreground) records data. Many of the preexisting gravity stations, which have been measured for years, survived Kīlauea's 2018 summit collapse.

This aerial view of the western part of Kīlauea Volcano's caldera was taken on August 6, 2018. The down-dropped block is faulted about 120 m (400 feet) below the caldera floor. Many 19th-century lava flows are exposed in the fault scarps. Halema‘uma‘u (not visible) is to the left of this photo. USGS photo by D.Swanson.

USGS Research Geologist Dr. Erika Lentz is conducting real-time kinematic GPS surveys on barrier island dunes, part of her research looking at how coastal landscapes respond to sea-level rise.

Following the draining of magma from Pu‘u ‘Ō‘ō on April 30, 2018, the crater was roughly 356 meters (1168 feet) deep. The upper part of the crater was flaring, with the deepest portion a narrower cylindrical shaft.

Explosive eruption columns of ash rising from Halema‘uma‘u at 11:15 a.m. on May 18, 1924 (top) and at 11:05 a.m. on May 15, 2018 (bottom) look similar.

The video was taken during an overflight of Pu‘u ‘Ō‘ō crater on Kīlauea's middle East Rift Zone. No major changes were observed, but the crater shape continues to change due to continued rockfalls.

The USGS Coastal Change Hazards Storm Team has forecast coast-wide levels of beach erosion, inundation and overwash due to Hurricane Florence's expected path and landgfall.
