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).

Earthquakes at Mount Rainier from 2010 to 2019. As shown in the graphic, fluids from the magmatic system beneath the volcano rise through existing cracks and weaknesses in the crust. Along with rainwater and ice/snow melt, these fluids combine to create a hydrothermal system within the volcano.

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.

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.

Volcano Awareness Month programs offered in January 2020 are depicted by these images. Clockwise from top left: ground cracks opened at HVO's former location atop Kīlauea in 2018; fissure erupting on Mauna Loa in March 1984; crater lake within Halema‘uma‘u at Kīlauea's summit; and visitors hiking a Kahuku trail in Hawai‘i Volcanoes National Park (NPS).
