Time-lapse multi-image movie of Pu‘u ‘O‘o Crater

A lava lake within the Halema`uma`u Overlook vent produced nighttime glow that was visible from the Jaggar Museum overlook and via HVO’s Webcam during the past week. The lake level rose over the past week and was about 50 m (165 ft) below the floor of Halema`uma`u on Thursday, May 9.

On Kilauea’s east rift zone, breakouts from the Peace Day tube remain active on the pali and on the coastal plain. Small ocean entries are active on both sides of the Hawai`i Volcanoes National Park boundary. A new breakout from a spatter cone on the northeast edge of Pu`u `O`o’s crater floor started on May 6 and has traveled a short distance north, following the path of the inactive Kahauale`a flow from last month.

One earthquake was reported felt in the past week across the Island of Hawai`i. On Monday, May 6, at 3:12 p.m., HST, a magnitude-3.4 earthquake occurred 5 km (3 miles) southeast of Pu`u `O`o at a depth of 8 km (5 mi).

Time-lapse movie of the Peace Day Flow area

This image was captured on Monday, May 6, by the Advanced Land Imager sensor aboard NASA’s Earth Observing 1 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 or very recently active lava flows. The vent for the current flow field is on the east flank of PuÊ»u ʻŌʻō. From the vent, lava is carried through a lava tube to the ocean entry at the coastline. Along the way, lava can break out from the tube, creating surface flows. Several areas of surface flows are visible in this image. Two small areas are on the pali in Royal Gardens subdivision. The largest is on the coastal plain, extending about 1.1 km (0.7 miles) out from the base of the pali. Several small hotspots are visible on the shoreline at the ocean entry, where lava exits the tube and spills into the water. Satellite images such as this help fill in observational gaps between field visits.
