Blogging on EARTH: AGU: Japan tsunami actually made population more vulnerable? When an earthquake begins, fast-moving P waves are detected, and emergency information can be disseminated before the arrival of slower-moving surface waves. But instead of unleashing it in a ground-rattling burst, slow quakes sluggishly release strain over time, and so are not hazards on their own. "As the reef moved up in the earthquake, the entire ecosystem was left exactly in place," study co-author Aron Meltzner wrote in a blog about his 2005 field experiences while a Ph.D. student at CalTech. Their analysis found that in addition to five previously confirmed supershear earthquakes documented in their data set, a further seven also met the supershear criteria. 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. 2019 TIME USA, LLC. Remember to drop, cover, and hold on when you get an alert or feel shaking.
