CSI: Rockfall Forensics
The next time you find yourself at the bottom of a cliff, make sure to look up.
This new "Science for Everyone" web article summarizes the June 2020 rockfall at Whitney Portal caused by the M5.8 Lone Pine, California earthquake.
New interagency report highlights alarming sea level rise predictions for all U.S. coastlines
The U.S. Sea Level Rise and Coastal Flood Hazard Scenarios and Tools Interagency Task Force published updated sea level rise projections out to 2150 and extreme water level probabilities for the Nation’s coasts out to year 2050. This effort offers information to help coastal communities prepare for the impacts of sea level rise.
Seven Decades of Coastal Change at Barter Island, AK
The Beaufort Sea coast along the northern edge of Alaska is a place of extremes. Home to the northernmost year-round settlements in the United States, this region sees round-the-clock daylight during the three-month Arctic summer and is shrouded in darkness and ice the rest of the year.

Landslide Forecasting in Puerto Rico
USGS is developing an island-wide monitoring network – the most comprehensive of its kind in the United States.
Long-Period earthquakes in Yellowstone: What do they mean?
Ever think an earthquake in one place is the same as an earthquake in another? It turns out that the style of an earthquake varies depending on its cause.
The M6.2 Petrolia Earthquake on December 20, 2021, Was Really Two Earthquakes
We can usually see the beginning and ending of one earthquake on a seismic record before another one starts. We’d like earthquakes to be well-behaved and happen one at a time... but often they don’t.
Photo and Video Chronology – Kīlauea – March 30, 2022
An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Intermittent lava activity is confined within Halema‘uma‘u crater, in the closed area of Hawai‘i Volcanoes National Park.
Scientists detect rejuvenated uplift near South Sister volcano.
Using satellite imagery and sophisticated GPS instruments, Cascades Volcano Observatory geophysicists have detected a subtle increase in the rate of uplift of the ground surface about 3 miles (5 km) west of South Sister volcano, Oregon. Episodes of increased uplift have been observed in this area before, and the volcano’s alert level and color code remain at NORMAL / GREEN.
Reflection on a 29-year career at USGS from Karen Morgan
For Women’s History Month, we reached out to Karen Morgan, retired coastal geologist from the St. Petersburg Coastal and Marine Science Center. Karen provided a reflection on the progression of coastal research and increase in women scientists during her 29-year career at USGS.
