论文摘要
MyShake是一个免费的公民科学智能手机应用程序,可提供与地震有关的一系列功能。全球可用的功能包括快速的地震通知,MyShake用户报告的地震损害的实时地图,安全提示和各种教育功能。该应用程序还使用加速度计来检测地震震动,并将波形记录到中央档案馆。此外,MyShake在加利福尼亚,俄勒冈州和华盛顿提供了地震预警警报。在这项研究中,我们比较了加利福尼亚州MyShake用户提供的毛毡摇动报告与美国地质调查局的“您感觉到的吗?”强度报告。 MyShake应用程序简单地问“您感觉到什么力量”,用户以五级规模报告。当报告在空间箱中平均时,我们发现与改良的Mercalli强度量表值相关,USGS根据更复杂的DYFI调查报告。因此,MyShake Feent报告也可以用于生成摇动强度图。
MyShake is a free citizen science smartphone app that provides a range of features related to earthquakes. Features available globally include rapid post-earthquake notifications, live maps of earthquake damage as reported by MyShake users, safety tips and various educational features. The app also uses the accelerometer to detect earthquake shaking and to record and submit waveforms to a central archive. In addition, MyShake delivers earthquake early warning alerts in California, Oregon and Washington. In this study we compare the felt shaking reports provided by MyShake users in California with the US Geological Survey's "Did You Feel It?" intensity reports. The MyShake app simply asks "What strength of shaking did you feel" and users report on a five-level scale. When the reports are averaged in spatial bins, we find strong correlations with the Modified Mercalli Intensity scale values reported by the USGS based on the much more complex DYFI surveys. The MyShake felt reports can therefore also be used to generate shaking intensity maps.
