USGS scientists Bruce Jaffe and Bruce Richmond visited Japan following the March 11, 2011 earthquake and tsunami. They collected time-sensitive data to help determine the height of tsunami waves at various sites and the distances the waves traveled inland.

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.

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.

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.
