Kīlauea Volcano — Flows Near Kapoho Ag. and Beach Lots

Near the coast, the northern margin of the flow field is still oozing pasty lava at several points in the area of Kapoho Agricultural and Beach Lots.

Kīlauea Volcano — Lava Flowing from Fissure 8

Lava within the fissure 8 cone roils and churns where it eupts from the vent and flows rapidly down the well-established channel. This image was captured via a Mavic Pro drone courtesy of the DOI/USGS Unmanned Aircraft Systems team.

Kīlauea Volcano — Fissure 8 at Night

USGS Unmanned Aircraft Systems image of fissure 8 looking east. Below the prominent fissure 8 cone, smaller vents above the original fissure emit volcanic gas. Lava has a brighter glow near the vent exit where it is more turbulent than in the downstream channel, which has portions of darker, cooled crust on its surface.

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).

Kīlauea Volcano — Sunrise at Halema`uma`u Crater

Inward slumping of Halema‘uma‘u continues in response to ongoing subsidence at Kīlauea Volcano's summit. This image, taken from a temporary observation post located at Volcano House, shows steep walls on the western side of the crater and sloping piles of rubble from rockfall events.

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.

Honolulu, Hawaii – Control efforts such as the removal of shipwrecks and application of chlorine may help mitigate the damaging effects of corallimorph, which is a type of invasive anemone, on valuable coral reefs in the Central Pacific Ocean, according to a new U.S. Geological Survey study.

This week marks 150 years since the largest earthquake to strike Hawaii in the last two centuries. Estimated to have been at least magnitude-7.9, this earthquake struck near Pāhala in the Ka‘ū District of the Island of Hawai‘i on April 2, 1868.

A recent issue of Volcano Watch [https://volcanoes.usgs.gov/hvo/hvo_volcano_watch.html?vwid=1232] looked at what the level of the lava lake within Halema‘uma‘u can tell us about how Kīlauea works and the hazards it poses.

March 15, 2018

A little more than ten years ago, conditions around Kīlauea Volcano's summit were much different than today. The caldera floor was open to the public, and the air above it was normally clear. Halema‘uma‘u was an impressive sight, but peacefully in repose.

This study implements the first continuous, real-time operational routine for tracking lava lake surface motion, applying the technique to the persistent lava lake at the summit of Kīlauea Volcano.

March 8, 2018

To set the stage for next week's Volcano Watch about the upcoming anniversary of Kīlauea Volcano's current summit eruption, this week we revisit the history of past Halema‘uma‘u eruptions. We do so by reprising parts of a Volcano Watch article written in December 2008, soon after the ongoing Halema‘uma‘u lava lake reached a milestone as Kīlauea's longest summit eruption since 1924.

Most people likely know that the USGS Hawaiian Volcano Observatory (HVO) uses seismometers and Global Positioning System (GPS) receivers for monitoring volcanoes. However, fewer people may be aware of the full extent of our volcano-monitoring toolkit.

Today's Volcano Watch begins with a question: Can you guess when the next slow slip event will happen on Kīlauea Volcano's South Flank? As a hint, the last one was in October 2015, and before then, events occurred in May 2012, February 2010, and June 2007. If this seems like a pattern, you're right.
