"Leaky" lava tubes spread flows only short distances from Pu‘u ‘Ō‘ō

Top image shows the forested Pu‘u Kahauale‘a cone on July 18, 2014, surrounded by the June 27th lava flow (light gray surfaces) with Pu‘u ‘Ō‘ō in distance. Below, what remains of the Pu‘u Kahauale‘a cone on July 23, 2015, with only the very top of the cone visible. "Leaks" from the lava tube system of the June 27th flow have nearly buried the cone in the past few weeks. Before the Pu‘u ‘Ō‘ō eruption began in 1983, the cone was nearly 30 m (100 ft) tall. It formed during an eruption a few hundred years ago, and continued breakouts from the tube will probably bury it completely in the coming weeks. USGS photos.
