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.

Close view of the Pohoiki boat ramp during this morning's overflight. The southern-most flow margin has not advanced significantly toward the Pohoiki boat ramp, but black sand and larger fragments from the entry areas have washed ashore to create a sand bar and beach at this site.

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.
