Pu`u `O`o and upper PKK flow
MLK vent area at south base of Pu`u `O`o. It has two holes near its top, at least one more than on January 21.
(Public domain.)
Line of fuming areas indicates site of PKK lava tube from near Pu`u `O`o. The fume comes from degassing lava flowing through the tube.
Active breakout between 2200 and 2300 feet along PKK lava tube. This breakout began during or just after an abrupt inflation earlier this morning.
Another view of same breakout, which by this time was about 500 m long along the east side of the PKK flow.
