Flooding in Soldier Pond, Maine, following rainfall and snowmelt that led to high water levels in the Fish and St. John Rivers in April and May of 2018. 

USGS field crews installed a temporary rapid deployment gage on May 2, 2018, at Soldier Pond in the Fish River to monitor flooding near Fort Kent in Maine.

USGS researchers drill a research well located on the south side of U.S. 90, 7.1 miles east of Brackettville, Texas. This core was drilled by USGS during field work for an oil and gas assessment for the Eagle Ford of the Gulf Coast Basins. Cores like these provide information on the various rock layers, such as their make-up, their age, etc.

USGS scientists deployed over 50 sensors along the coast of Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey and Delaware to study a Nor'easter that affected the Northeast in March of 2018.

The choice when issuing earthquake warnings is to: 1) issue alerts for weak shaking and potentially provide long warning times, but risk sending alerts for the many events that do not go on to produce damaging ground shaking, or 2) issue alerts only when ground shaking is expected to be damaging, with the tradeoff that the alert will be sent much later, reducing

Damage from a major post-wildfire landslide that occurred on 9 January 2018 near Montecito, Santa Barbara County as a result of the 2017 Thomas Fire.

The Dec. 4, 2017 Thomas fire, Southern California's largest wildfire on record, burned more than 280,000 acres across Ventura and Santa Barbara counties for nearly a month.

USGS geologists deployed to Santa Barbara County to support a geohazard assessment of the Montecito area
