Photos taken two weeks apart show the rise of water in Halema‘uma‘u. A white arrow denotes a large rock along the edge of the lake for comparing water levels in the two images. The water continues to rise at a rate of approximately 15 cm (6 in) per day. USGS photos by M. Patrick.

The 1880-1881 eruption of Mauna Loa produced lava flows that came within 1.7 km (1.1 mi) of the Hilo Bay shoreline. This painting by Charles Furneaux, "Night View 1880–1881, Eruption from Hilo Bay," illustrates the first two flows as they would have been in November 1880. In reality, however, both flows would not have been visible from this vantage.

USGS scientists collaborate with Sri Lankan scientists from the National Building Research Organization (NBRO) on the installation of rainfall and soil moisture instrumentation on an active landslide in southwest Sri Lanka. The station provides real-time data including rainfall and soil moisture content of an active landslide.

Nearly 85 million people around the world are currently considered “food insecure,” and that figure continues to grow. Remote sensing technology enables scientists to feed data into the Famine Early Warning Systems Network (FEWS NET), which in turn can issue alerts that guide the distribution of humanitarian aid.

Wildfires burned across Lebanon in mid-October, 2019. A pair of images taken just ten days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires. North of the fire scar is the country's capital, Beirut.

Every year, the USDA’s National Agricultural Statistics Service (NASS) uses data from satellites like Landsat to estimate crop types and crop yields in the United States. The result is the Cropland Data Layer (CDL), which offers an annual look at more than 100 crop categories across the country.

After collecting a sample from the well using the narrow sampler shown, HVO staff transfer the water sample into a container. The water is collected periodically for chemical analyses so that changes in the water composition can be tracked. For more information about the Keller Well, please see HVO's Dec.

The communications hub at Pu‘u ‘Ō‘ō is precariously perched on the north rim, which is actively collapsing. This hub, and the PN cam behind the hub (to the left of image) will ultimately fall into the crater as the north rim continues to collapse.

Did you know the USGS has been studying groundwater since we were founded? USGS first measured the groundwater level at the well in this photo in 1918, over one hundred years ago! How often water levels are measured at a site in the USGS groundwater monitoring networks varies, depending on the scientific purpose of the measurement.

In this video, you can hear the honks and quacks of geese and ducks ring through the air, as birds fly in every direction above a wetland. This video was captured at Sacramento National Wildlife Refuge in November 2019, not long after geese and ducks began to arrive to spend the winter in the California Central Valley.
