美国地质调查局(USGS)日前发布的一项研究报告称,智能手机及类似设备中的GPS接收器,能探测到大地震中由断层运动造成的持续地层运动,报告发表在4月10日的美国科学促进会杂志《科学进展》上。地震早期预警系统(EEW)能自动探测一场地震的开始,在人们体验到震感之前迅速发出警报。这一系统目前仅在日本和墨西哥等全球少数地区运作。虽然对级别更小,仍有潜在破坏性的地震不 A recent study released by the US Geological Survey (USGS) reported that GPS receivers in smartphones and similar devices can detect continuous ground motion caused by fault movement during a major earthquake. The report was published on April 10 American Association for the Advancement of Science magazine on Science. The Early Warning System (EEW) of Earthquake can automatically detect the start of an earthquake and quickly alert people before they feel the earthquake. The system is currently operating in only a few parts of the world, including Japan and Mexico. Although there are still potentially damaging earthquakes to the lesser level, no
