USGS scientists investigate trees knocked over by the tsunami at the mouth of Taan Fjord. Flow depth here was likely 5 m based on the height of branches stripped off trees in the background. This event had the 4th highest tsunami runup ever recorded.

Main hydrothermal features of the new (2016) 3-D model of the subsurface at Long Valley Caldera. This schematic is based on a survey of the electrical properties of the earth (magnetotellurics) below. Arrows show subsurface water flow, with colors keyed to changing water temperature, from blue (cold) to red (hot). Purple arrows show an extinct hot water pathway.
