Davina Passeri invited to present on barrier island evolution at Deford Lecture Series Release Date: February 25, 2021 Davina Passeri of the USGS St. Petersburg Coastal and Marine Science Center has been invited to present a talk titled, “Modeling decadal barrier island evolution under future storms and sea level rise” at the University of Texas DeFord Lecture Series on February 25. This model shows what Dauphin Island, Alabama, may look like under moderate storms but with increasing rates of sea level rise (Passeri and others, 2018). (Credit: RC Mickey, images. B.

Earthquake early warning system tested in Washington

Residents of King, Pierce and Thurston counties received a test wireless emergency alert. Author: Keely Chalmers Updated: 8:27 PM PST February 25, 2021 PORTLAND, Ore. Feb. 28 marks the 20-year anniversary of the Nisqually earthquake. It was centered near Olympia, Washington, but shook much of the Pacific Northwest. To mark that upcoming anniversary, scientists in Washington sent out a test earthquake warning alert.  Residents of King, Pierce and Thurston counties received a test wireless emergency alert. It was a public demonstration of the ShakeAlert earthquake early warning system.  The system relies on thousands of sensors both onshore and off. When an earthquake hits, those sensors will alert us that the quake is heading our way. But, scientists stress, the alerts will give only seconds warning. But it will be enough time to drop, cover, and hold on.
