USGS HVO Press Release — Lava Enters Tube System At Pu‘u ‘Ō‘ō

Release Date:

Field observations of the Pu‘u ‘Ō‘ō–Kupaianaha eruption today show that lava has re-entered the old tube system near Pu‘u ‘Ō‘ō.

Lava was seen moving through the tube down to an elevation of about 2400 ft, less than 0.5 miles from Pu‘u ‘Ō‘ō. There is no indication of how far the lava will continue to flow or whether it will break out of the tube system onto the surface. Breakouts seem likely, however, because parts of the tube have probably become clogged since the tube was last active in January. This activity is part of Episode 55, which began on February 24 when lava appeared in the crater of Pu‘u ‘Ō‘ō after 24 days of inactivity.

Daily updates about ongoing eruptions, recent images and videos of summit and East Rift Zone volcanic activity, maps, and data about recent earthquakes in Hawaii are posted on the HVO website at
