Serapeum, a Roman Marketplace in Pozzuoli, Italy, records deformation of Campi Flegrei caldera over two millennia. It was built above sea level about 2000 years ago, but mollusk borings on the large marble columns indicate that it subsided by 7 meters (23 feet) below sea level before being uplifted above sea level once more in the past several hundred years.

A USGS employee takes a wading measurement of streamflow on Leidy Creek at Togwotee Pass. Bear tracks on the fresh snow and seven grizzlie sightings were a good reminder to be bear-aware when taking measurements in this area.

Hawaiian Volcano Observatory field crews establish a new MultiGAS volcanic gas monitoring station on the south side of Kīlauea Volcano's caldera. Currently, sulfur dioxide emission rates from the summit remain low. The station will collect data to track emission rates and concentrations over time. Photo by Frank Younger.
