Earthquake hazard map showing peak ground accelerations having a 2 percent probability of being exceeded in 50 years, for a firm rock site. Black box outlines Yellowstone region. The map is based on the most recent USGS models for the conterminous U.S. (2018), Hawaii (1998), and Alaska (2007).

Yellowstone earthquakes that occurred during 2010-2019. Blue symbols indicate events that occurred as part of swarms, while red indicates non-swarm seismicity. Map courtesy of the University of Utah Seismograph Stations.

Beryl Spring's strongly boiling blue pool is about 8 m (25 ft) wide and contains high-chloride liquid water with a near-neutral pH. Immediately behind the pool is a loud, hissing fumarole producing a white cloud of steam. USGS Photo by Pat Shanks, 2002.

Imperial Geyser looking south. This hot spring pool is about 30 m (about 100 ft) across and contains alkaline-Cl waters with a steam vent in the pool and mudpots outside the pool area (in the upper right part of this photo). USGS Photo by Pat Shanks, 2019.

The December 18 overflight provided updated aerial photographs of Kīlauea summit, covering the caldera floor and showing the current size of the water pond in Halema‘uma‘u crater. The label "downdropped block" shows the large portion of the caldera floor that subsided, along with the Halema‘uma‘u region, during the 2018 eruption.

The December 18 overflight provided updated thermal images of Kīlauea summit, covering the caldera floor and showing the warm surface of the water pond in Halema‘uma‘u crater. A band of warm temperatures persists along the new cliff formed during the 2018 subsidence.

An HVO geologist uses a high-precision Global Positioning System (GPS) unit to collect latitude, longitude, and altitude data on a down-dropped portion of Kīlauea's caldera.
