During the March 21, 2024 lahar evacuation drills, thousands of students walked to the Washington State Fairgrounds in Puyallup, Washington to practice evacuating from a lahar generated by Mount Rainier. A lahar, or volcanic mudflow, could reach this area in about 3 hours.

USGS installed an array of seismometers in a field in Gaziantep, Turkiye in order to record ambient noise and earthquakes, including the aftershocks of the devastating earthquakes of 2023. Robert Sickler of the USGS in the foreground and an AFAD employee in the background.

Annual number of earthquakes with a magnitude of 3.0 or larger in the central and eastern United States, 1973–2022. The long-term rate of approximately 25 earthquakes per year increased sharply starting around 2009.

Scientists at the USGS are installing sensors in Wellfleet MA, part of the Cape Cod National Seashore to evaluate the long-term and short-term chemical and geomorphic changes within wetlands. 

As sea-level rise accelerates, vegetation transitions are increasingly observed and USGS scientists are busy assessing those changes. Shoreline at the Cape Cod National Seashore in Wellfleet, MA.

An eruption at the summit of Kīlauea volcano began on September 10, 2023. The main fountain, which HVO geologists estimate is approximately 50 meters tall, is on the eastern margin of Halemaʻumaʻu crater. As of approximately 4:30 p.m.

From the Uēkahuna overlook, the new eruption at the summit of Kīlauea is visible. The farthest east fissure is near the to margin of downdropped block that formed during the 2018 summit collapse. The base of the main fissure, which is farthest west (right on the image), is approximately 70 meters wide.

The new eruption at the summit of Kīlauea volcano on September 10, 2023. After about an hour of increased seismic activity and uplift, HVO scientists observed the start of the eruption at approximately 3:15 p.m. HST.
