USGS scientists continue to monitor some of the cracks in the lower East Rift Zone to check for any significant changes. This scientist is using an Infrared thermometer to record the temperature within the ground cracks.

Map of earthquakes in the Yellowstone area in 2017 that were individually located using traditional methods by University of Utah Seismograph Stations. The Maple Creek earthquake swarm, northwest of the caldera (red outline), is the second-longest-lasting ever recorded in the region. Black line shows Park boundary, and white lines are roads.

The USGS Hawaiian Volcano Observatory continues to closely monitor volcanoes and earthquakes on the Island of Hawai‘i. On this map, which shows earthquakes that occurred beneath the island between August 6, 2018, and November 14, 2018, the size of each circle depicts earthquake magnitude and color indicates earthquake depth, relative to mean sea level.

Fissure 22 was active in late May near Lanipuna Gardens subdivision, which is now mostly buried by lava flows. During the later stages of Fissure 22 activity, small strombolian-style explosions built a symmetric cinder cone over the vent.

GPS time series from station NRWY, near Norris Geyser Basin in Yellowstone National Park. The three plots show how the station is moving in a north-south direction (top), east-west direction (middle), and up-down direction (bottom).
