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.

A team of USGS hydrologists and technicians prepares to take an acoustic Doppler current profiler (ADCP) out on the Red River in downtown Fargo, N.D., to measure streamflow during the 2013 flood.

This is a typical GPS monitoring station example from Hualālai Volcano.

The September Lobe monitoring station is part of the network of monitoring stations that detects and reports subtle changes in the volcanic vent area. At 2150 m (about 7100 ft) elevation, maintenance is performed during good weather to keep the station fully functional.

A vigorous flow was erupted on the floor of Pu‘u ‘Ō‘ō crater starting early this morning from a cone near the north rim, but a smaller flow was also erupted from a spatter cone near the south rim around noon. This photo captures a burst of spatter from the southern cone as the small flow was erupted.

Breakouts have diminished over the past few days on the Kahauale‘a flow (heading northeast of Pu‘u ‘Ō‘ō), and the flow front has not advanced significantly since April 8. Compare today's thermal image with that from the April 8 overflight. During today's flight, there were no active breakouts at the flow front.

Lava erupted this morning from the cone near the north rim of Pu‘u ‘Ō‘ō crater, with a small portion of the flow emptying out onto the east spillway. This new flow brings the floor of the crater slightly closer to the north crater rim.
