Combining quantum sensors with traditional seismographs could provide more precise data for researchers to use in earthquake models, leading to better hot-spot predictions and more effective warning systems.
Here’s How Earthquakes Cause TsunamisWhile these measurements can help triangulate the quake’s epicenter, they have significant limitations. “This gives some warning but means [seismographs] can't produce decisive event warnings because they only see something when the ground starts to shake,” Boddice adds.the earthquake happens, forcing scientists into a race against time to warn at-risk areas before it is too late.a quake, giving valuable time for issuing a warning.
“By adding a network of permanently monitoring gravimeter sensors, if you detected a mass shift caused by the plate movement on multiple detectors simultaneously, you’d have an earlier warning,” Boddice says. That could then be confirmed once the accelerometers started to detect wave arrivals as the gravitational signal travels at light speed.
Though the warning window may be expanded only slightly, Boddice believes that this extra time can still make a difference in reducing fatalities during an earthquake.
