Advancing earthquake science worldwide
Traditional earthquake early warning systems detect the fast-moving, but less-powerful P-waves that radiate from an earthquake. From there, they quickly estimate the earthquake’s location and magnitude and send out an alert, often just seconds before the more powerful S- waves arrive (check out the difference between the different waves here). … Continue Reading »
22 August 2018–The bright flashes that lit up the evening skies near Detroit, Michigan earlier this year were not the only signs of the meteor that disintegrated in the atmosphere on 17 January 2018. The meteor explosion was also captured by infrasonic microphones and seismometers, offering a rare chance to … Continue Reading »
Seattle is the site of SSA’s 2019 Annual Meeting. It’s also one of the major cities along the Cascadia Subduction Zone, the volatile seismic region that stretches from Northern California to Vancouver Island. Formed by the Juan de Fuca, Gorda and Explorer plates dipping below the denser North American plate, … Continue Reading »
1 August 2018–Using an array of coffee-can sized geophones deployed for about a month in backyards, golf courses and public parks, researchers collected enough data to allow them to map the depth and shape of the San Gabriel and San Bernardino sedimentary basins of Los Angeles, California. Seismologists think these … Continue Reading »
Organizing a technical session might seem daunting, but there’s a lot that early-career scientists can gain from the experience. Here’s some advice on why – and how – you should consider organizing a session for SSA’s 2019 Annual Meeting. Learn and network The two main benefits of organizing a technical … Continue Reading »
Say the word “seismograph,” and many minds go directly to the image of a machine scribbling out ink lines to trace the shaking of an earthquake. Seismology has always been a profession especially known for its tools, even though the field has moved far from the stylus and drum recorder. … Continue Reading »
