Volcano Watch: Kilauea activity update for July 30, 2015

Kīlauea’s summit lava lake level fluctuated this past week between about 50 and 70 m (164 – 230 ft) below the vent rim. Kīlauea’s East Rift Zone “June 27th lava flow” continues to feed widespread breakouts northeast of Puʻu ʻŌʻō.

Volcano Watch: “Leaky” lava tubes spread flows only short distances from Puʻu ʻŌʻō

By spawning so many short-lived flows over a large area, the leaky nature of the Pu‘u ‘O‘o lava tubes means that no single flow has been able to capture the volume of lava needed to develop into a sustained, rapidly advancing flow similar to the June 27th flow late last year.

This thermal image of the Puʻu ʻŌʻō crater, sent by text on May 7, 2015, to USGS Hawaiian Volcano Observatory geologists, is an example of the thermal camera alarm system developed at HVO. In this case, the alarm was triggered by the appearance of new lava on the floor of Puʻu ʻŌʻō, seen here as the brightly colored (hot) region in the image. The temperature scale at right is in degrees Celsius. USGS webcam image.

Scattered breakouts remain active northeast of Puʻu ʻŌʻō on the June 27th lava flow, but have not advanced significantly over the past month. This photo shows the farthest reach of active lava on the flow field today, which was about 8 km (5 miles) northeast of the vent on Puʻu ʻŌʻō. Minor brush fires were active where lava was entering forest. Photo taken Friday, June 19, 2015 courtesy of USGS/HVO
