Timelapse video of the water pond at Kīlauea summit
Timelapse video of the water pond at Kīlauea summitThis timelapse video covers 1.5 hours and shows the motion of the water surface at the summit of Kīlauea. Along the shoreline, areas of apparent water influx are visible, often with a slightly greener color. Shifting steam on the surface attests to the high temperature of the water and the winds at the bottom of the crater.

Fires in Lebanon
Wildfires burned across Lebanon in mid-October 2019. A pair of images taken just 10 days apart by the European Space Agency's Sentinel-2A satellite show the burn scar from one of the larger wildfires.

Klamath River mouth
A view of the mouth of the Klamath River where it meets the Pacific Ocean in northern California. The river runs from Oregon to California. Four dams along the Klamath are pending removal. USGS is studying coastal watershed response to dam removal, including long-term before-after/control-impact (BACI) studies.

The Great California ShakeOut (2019) Role Play Exercise - Biola Univ.
The Great California ShakeOut (2019) Role Play Exercise - Biola Univ.Each year the State of California promotes a ShakeOut event where local citizens practice earthquake response and preparedness. This video shows footage from the 2019 Great California ShakeOut, which was hosted at Biola University in La Mirenda, CA. Video includes footage of the initial ShakeAlert announcement that blared across campus.

USGS scientists measured gases in an area uprift of the 2018 fissure system on NUSGS scientists measured gases in an area uprift of the 2018 fissure system on November 8. In this area, vegetation has died because of lingering heat and steam. In some areas of Kīlauea's lower East Rift Zone, residents report smelling gases that are likely generated by decaying organic matter rather than magma degassing. USGS image by P. Nadeau.

USGS scientists monitor gases on Kīlauea's lower East Rift ZoneOn November 8, 2019, USGS volcano scientists visited Kīlauea's Lower East Rift Zone to measure ambient gases, as well as the soil carbon dioxide (CO2) flux and temperature. This photo, looking in a southeast direction, shows some steaming uprift of the 2018 fissure system.

Black racer snake with snake fungal disease
Black Racer snake (A) The epidermis over much of the body, but cranially pronounced, has multifocal to coalescing dull white to pale gray foci. (B) Multiple scales around the head are thickened and roughened. (C) Ventrally, there are multiple dull white to grey foci of up to 8 mm size, occasionally with central indentations.
