Volcano observatories across the United States work together to ensure efficient and thorough monitoring of the nation’s active volcanoes. This collaboration is particularly evident during a crisis, like the 2018
The pali (cliffs) of Kīlauea’s south flank are some of the volcano’s most striking features. Reaching up to 500 m (1500 ft) high, they stand out against the otherwise gentle

One year ago, activity on Kīlauea Volcano was remarkably different than it is today. Lava was flowing toward the sea, robust ocean entry plumes were fumigating coastal areas, and island
Hawai`i residents are likely familiar with the Volcano Activity Updates that the Hawaiian Volcano Observatory issues for Kīlauea and other active Hawaiian volcanoes. These updates, which provide situational awareness of
Kīlauea Volcano, on the Island of Hawai‘i, has two rift zones. The East Rift Zone is longer, with 50 km (about 31 miles) on land plus another 80 km (about
Since the early 1990s, scientists have used radar satellites to map movement, or deformation, of Earth’s surface. Interferometric Synthetic Aperture Radar (InSAR) calculates the difference between two radar images acquired
The USGS Hawaiian Volcano Observatory, along with its partners at NOAA’s Pacific Tsunami Warning Center and the National Strong-Motion Project, operates a network of seismic monitoring stations on the Island
