Another entry point has two larger lava streams entering the water. The lava fragments due to cooling and disruption by the battering surf, and some of these pieces float on the water's surface in front of the entry point (see lower left portion of photo).

Over the past week this spatter cone on the floor of Pu‘u ‘Ō‘ō crater has been the source of several large, but brief, lava flows on the crater floor. Today, the cone was producing pulsating gas jetting sounds.

After a 12 km (7.5 mile) journey from the vent on Pu‘u ‘Ō‘ō cone through a lava tube, lava pours into the ocean in narrow streams at one of the eastern entry points.
