April 27, 2011, flooding of the Souris (Mouse) River near Westhope, North Dakota. The small building is the U.S. Geological Survey gage house and is normally on the river bank and raised so that one needs to take stairs up to get into the gage house. There is also an access road next to the gage house and electrical pole.

In this close-up view of the lava lake in Pu‘u ‘Ō‘ō, lava upwells at the west edge of the lake (bottom center of the photo) and flows toward the east (top of photo) where the mostly degassed lava sinks back down, presumably circulating back into the vent.

Pu‘u ‘Ō‘ō continues to host a small lava lake at the bottom of the crater. Minor spattering and overturning of the lake surface was observed by field crews today.

Lava reappeared in Pu‘u ‘Ō‘ō crater on Saturday morning (March 26), covering the floor of the crater with a small lava lake.

Wes Thelen began his new job as HVO's Seismic Network Manager amidst a flurry of volcanic and seismic activity during Kīlauea Volcano's recent Kamoamoa fissure eruption, shown here on March 9, 2011.

A small lava lake, confined by slightly elevated levees, is active at the bottom of Pu‘u ‘Ō‘ō crater. The lake is roughly the same size as a football field.

This thermal image was taken from the south rim of Pu‘u ‘Ō‘ō crater, showing the lava lake within the crater. Hotter surfaces, such as the narrow zones between crustal plates, are shown by yellow and white colors. Cooler surfaces, such as the cooled lava around the lake, are shown by blue and black colors.
