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.

Looking northwest at the lava pond on the floor of Pu‘u ‘Ō‘ō crater. At the time of the photograph, the level of the lava pond was about 3 m (10 ft) below the floor of the crater.

An hour later, the lava had risen high enough to spill over the pond walls and expand across the crater floor.

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.

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.
