Two explosions in as many days were triggered by rocks falling into Kīlauea Volcano's summit lava lake. The event shown above occurred around 12:26 p.m., HST, today (Thursday, October 20). The other explosion happened around 7:45 a.m. on Wednesday, October 19. Both events are reminders why the area around Halema‘uma‘u Crater remains closed to the public.

Following today's explosion, spatter (bit of molten lava) and fragments of solid rock littered this closed section of Crater Rim Drive in Hawai‘i Volcanoes National Park.

High tides are one challenge of working in tidal wetlands! Here the marsh platform is completely submerged during a spring tide. The boardwalk, which scientists use to access the site, is also under water during this extreme high tide, while the solar panels powering some instruments remain dry.

On Saturday, October 15, Kīlauea Volcano's summit lava lake overflowed the vent rim between 1:00 and 2:00 p.m., and again around 6:30 p.m., HST. In this image, captured by HVO's K2 webcam, you can see small spill-overs (shiny black lava) on the east (far left) and west (right) sides of the vent rim.

Low-altitude oblique photography taken before Hurricane Matthew (Sept. 6, 2014) and after (Oct. 13, 2016) in Flagler Beach, FL, shows that waves washed away part of Highway A1A and obliterated a 5.2-meter (17-foot) dune.

With brisk trade winds today, spectacular views of Kīlauea Volcano's eastern Kamokuna lava delta were possible from outside the closed area on the east, or Kalapana, side of the ocean entry.

Using the telephoto feature on a point-and-shoot camera (from the same location as the left photo), this image captured lava streaming into the ocean at the leading edge of the lava delta.

This skylight, a "window" into the active lava tube that carries lava from the vent to the sea, is located inland of the Kamokuna ocean entry. It is a sobering reminder why visitors are encouraged to remain outside the closed area, which Hawai‘i Volcanoes National Park has cordoned off with a rope line and warning signs.

It is possible to see the skylight without entering the closed area, and with a camera or smart phone, you can zoom in for more detail, as shown in this image.

This video clip shows typical spattering activity in Kīlauea's summit lava lake. This spattering was occurring along the eastern margin of the lake on the evening of October 5.

On October 6, 2016, scientists lower an instrument package on a taut-wire mooring into the canyon. The sediment trap (long funnel-shaped device) is designed to capture mud and sand carried in turbidity flows; the other sensors measure currents and suspended sediment.

The KALAHIKIOLA Congregational Church in KAP‘A‘āU was extensively damaged on October 15, 2006, by two earthquakes (magnitudes 6.7 and 6.0) off the northwest coast of Hawai‘i Island. The earthquakes were felt throughout the State of Hawaii, but the greatest damage occurred in the North Kona and Kohala Districts of the Island of Hawai‘i.

This photograph shows spattering at the southeast margin of Kīlauea's summit lava lake, as viewed from the west. This is the most common area on the lake to have spattering, but, because it is almost directly below the camera location, it is not visible in our webcam images.

This morning, spattering along the eastern margin of Kīlauea's summit lava lake built an overhanging ledge that was attached to the Overlook Crater wall. In this image, a few long stalactites can be seen dangling from the overhang (lower right). These stalactites were flexible enough to be swinging back and forth.

This satellite image was captured on Thursday, September 29, by the NASA/USGS Landsat 8 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds.

This video shows spattering in two locations of Kīlauea's summit lava lake. In the first segment, spattering is active in a small area in the southern portion of the lake. In the second segment, spattering on the east margin of the lake has created an overhanging ledge with dangling lava stalactites.
