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 »
