During hurricanes the USGS deploys storm-surge monitoring instruments along the coasts, sounds, and bays in impacted areas to gauge how high hurricanes push water in rivers, bays and other areas. The sensors are crucial for forecasting future storms and assessing hurricane damage.

Extensive, contiguous mortality of piñon pine, ponderosa pine, and Douglas-fir trees, killed in the first afternoon and evening of the 2011 Las Conchas Fire in the Jemez Mountains, New Mexico. Forest drought stress is highly correlated with mortality from poor growth, bark beetle outbreaks, and high-severity fire.

Electronics inside the instrument shelter, which includes a high-data-rate transmitter (upper right) and line-of-sight receiver (middle left). The line-of-sight receiver picks up transmissions from the remote rain gage at the look-out area at the top of the Montezuma Pass, Arizona.

Upper aerial photograph shows Rodanthe, NC, looking south along the coast on August 30, 2011, three days after landfall of Hurricane Irene. The central and lower aerial photographs show pre-storm and post-storm extreme coastal change, with the yellow arrow in all 3 photographs pointing to the same cottage.

Frank Perret's photos from early July 1911 showing the island in the lake at the bottom of a smaller Halema‘uma‘u Crater. The view is looking southwest and the ledge up near the west rim was known as the January 1910 bench, a remnant of an earlier lava level in the crater.

Electronics for controlling the moving arm in the open pressure housing.

Photograph of cutbank outcrop at Home Bay marsh, showing the subsurface stratigraphy to 90-cm depth exposed during low tide. Holes about halfway down the exposure are from burrowing crabs populating a narrow zone at the transition from underlying inorganic mud deposits to overlying peaty mud to peat deposits.

A Scroll down to the photo taken on June 29 to compare the amount of uplift the floor of the crater has endured in the last month. This photo was taken from a similar spot to the lower right of the three photos posted that day.
