Amateur Radio Helping to Fill Earthquake Report “Donut Holes” 02/25/2021
An
article describing how radio amateurs can help fill the information “donut hole” by providing post-earthquake “did you feel it” (DYFI) reports via
Winlink HF radio email appeared on February 22 in the American Geophysical Union (AGU) magazine
Eos. As the article points out, “Ham radio networks gear up to provide real-time, on-the-ground information about earthquake shaking and damage when other communication pathways are knocked out of commission.” Authors of the article were David J. Wald of the US Geological Survey (USGS), Vincent Quitoriano, and Oliver Dully, K6OLI.
As the article explains, DYFI uses a questionnaire to gather individuals’ experiences and observations, and USGS uses the information to evaluate the shaking intensity at that person’s location. DYFI has been in operation since 1999 in the US and 15 years around the world, during which the USGS has gathered mo

Living through almost a year of the pandemic and the worst wildfire season on record in California has a lot of Bay Area residents on edge.
And, more recently, several small earthquakes have jolted the Bay Area, including a 3.9 magnitude quake Sunday near Gilroy, and others in Berkeley, Concord and Aromas.
The temblors caused no significant damage but perhaps rattled some nerves and raised concerns: Could a bigger event be on the way?

What if you could get a notice of earthquake shaking before itâs felt at your location? The technology exists, is already in place along most of the West Coast and operational for key infrastructure systems such as automatic water valve shutoffs and starting back-up generators.
ShakeAlert®, an earthquake early warning system powered by the U.S. Geological Survey, uses science and technology to detect significant earthquakes quickly so alerts can reach people before shaking arrives. These seconds of advance warning allow people and systems to take actions to protect life and property from destructive shaking.
In Oregon, ShakeAlert-powered alert delivery to wireless devices such as cell phones via the Wireless Emergency Alert (WEA) System, mobile apps and other technologies will begin as of 10 a.m. on March 11. No specific action is needed for WEA alerts and for cell phones using the Android operating system. The mobile app, QuakeAlertUSA, is currently available in Oregon.
