Damage as seen in Natori, Japan, in May 2011. The March 11, 2011 magnitude 9.1 earthquake off the east coast of Japan caused an epic tsunami. USGS scientist standing near the wrecked boat, and a car on the road, provide scale. Damage to the building indicates a 10-meter flow depth.

USGS Hydrographer measures streamflow at Birds Point-New Madrid floodway using a tethered acoustic Doppler current profiling from a moving boat. USGS scientists are measuring the amount of water spilling into the New Madrid floodway as a result of the recent intentional breaching of the Birds Point Levee in Missouri in support of the Corps of Engineers operation.

Four tan cables, each 6 kilometers long, trail behind R/V Marcus G. Langseth. These cables record seismic sound waves that travel down into the Earth and reflect back from layers beneath the seafloor. The green cables provide the sound.

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.

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.

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.

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.
