A close-up of the active vent on the floor of Pu‘u ‘Ō‘ō crater.

The lava pond in the vent cavity of the Halema‘uma‘u Overlook vent during the rise phase of a rise/fall cycle. In this photo, the lava pond is 95 m (312 ft) below the floor of Halema‘uma‘u crater. When the pond level is high there is very little fume, allowing for unusually clear views.

A small lava flow erupted from the septum between two vents on the east wall of Pu‘u ‘Ō‘ō crater on Sunday, February 6. The hole on the right, which is no longer active, was the original east wall vent. The fuming hole behind the new lava flow is the current east wall vent.

This week, the northwest vent was producing lava flows on the floor of Pu‘u ‘Ō‘ō crater. The northeast cone is in the background, as well as the small lava flow that ran down the east wall of the crater.

A new rootless shield is building along the TEB tube above the pali. Lava began erupting in the area on February 4, and has built up a shield and lava pond about 10 m (33 ft) high.

Lava began erupting from the septum between the two openings on the east wall of Pu‘u ‘Ō‘ō crater the morning of February 17, just after 7:00 am.

Flows from the more northerly vent are crossing a small portion of the crater floor and filling in the southern opening.

A view looking south at this morning's new breakout. The southern opening is completely filled in and the flows are expanding across the crater floor. The geologist on the opposite rim is 1.8 m (6 feet) tall.

At the same time the vent on the east wall was erupting, a small lava pond fed by the northeast vent began to overturn.

After recovering from last week's DI event, the lava surface in the Halema‘uma‘u Overlook vent returned to about 80 m (260 ft) below the floor of Halema‘uma‘u Crater. The north/northwest rim of the vent (right side of photo) is still noticeably overhung, making future collapses very likely.

The northeast vent on the floor of Pu‘u ‘Ō‘ō is once again producing lava flows that are repaving portions of the crater floor. The fuming area on the back wall is the main source of last week's activity in the crater.

As the Souris River flooded during the early summer of 2011, it overcame levees in the city of Minot, N.D., causing about 11,000 people to evacuate their homes. The record-breaking flood crested on July 25 at over 26,000 cubic feet per second (cfs) and 24 feet - nearly 13 feet over flood stage - according to U.S.

USGS scientists measure streamflow on a tributary of the Souris River in Foxholm, N.D., about 30 miles northwest of Minot. The team is using an acoustic Doppler current profiler (ACDP) to measure streamflow.

USGS hydrologist Chris Laveau is interviewed by media from the Broadway Bridge in downtown Minot, N.D. Dikes on the right of the photograph help control flooding in the downtown area.
