Supershear earthquakes are more likely to happen along long, mature faults like the San Andreas, where many years of activity have ground away a lot of the twists and bumps that might slow down an earthquakes energy. Mexico and Japan adopted earthquake early-warning systems years ago, but they are still imperfect (both have issued false alarms). Early warning systems measure ground movement during the fast P waves to predict how much shaking the S waves will cause, and then send out an alert. earthquakes by 29 Feb 2016 earthquakes Where fire freezes: All eyes, ears and instruments on Iceland's volatile volcanoes Vital seconds: The journey toward earthquake early warning for all Small tremor could have triggered big Chilean quake March 29, 1936: Notes on Earth's Inner Core Tohoku tsunami may have gotten a boost from submarine slump rdegroot@usgs.gov published 10 February 22. The southern island of Enganno is "sinking a little too fast," says Rishav Mallick, first author of the new study and a Ph.D. candidate at Nanyang Technological University in Singapore. It employs a West Coast-wide network of sensors to detect the quakes before they hit, in hopes of spreading the word as far and wide as possible. In a supershear quake, the fault in the 1906 case, the San Andreas ruptures faster than seismic shear waves can travel through rock. But using a technique called backprojection, which analyzes delays between seismic waves to determine how fast they are traveling, the team realized that supershear earthquakes are just as common in the ocean as on dry ground they just have been historically a lot harder to monitor. It has been 19 years since the last significant quake rolled through California the magnitude 6.7 earthquake in Northridge in a .
