是的,你可以用加速度计测量地震能量。大多数人做的。* *有三种方法来测量地震能量:位移x美元,速度\点{x},美元或美元加速\ ddot {x} $。弹簧设备[如何][1]测量速度;硬弹簧装置(MEMS)[2]和[相对重力仪][3]测量加速度:加速度计。那些用在地震学和勘探地球物理学很精确。我写了各种仪器用来测量地震能量在一段(博客)[4]。关于地震检波器摘录:>地震仪是精密仪器不习惯在探索>地震学因为他们通常很笨重,需要小心>设置和校准。大多数现代模型是加速度计,>这样相对重力仪测量地面加速度>力在证据质量。地震仪可以检测频率>宽带,在0.001赫兹到500赫兹的顺序:19个八度! Short story: When digital seismic receivers arrived on the scene in Calgary in the early 2000s, there was a lot of skepticism. We spent a lot of time comparing them to traditional geophones. The conclusion: they were about the same. [Here's one comparison][5] by Michael Hons at CREWES, and [here's another][6]; [here's yet another][7] from one of the big manufacturers, Sercel (now CGG). Finally, [here's a presentation][8] more oriented around earthquake seismology. **Okay, but I was talking about the accelerometers in iPhones!** Oh, sorry. As @Fred points out in his answer, consumer-grade MEMS accelerometers (as you might find in a phone or latop) may not have the sensitivity or calibration that a researcher would want, but one might compensate somewhat for this with multiple measurements, e.g. an array of devices. In other words: quantity, not quality. (This is perfectly legit: we do it in exploration seismics too.) [Dashti et al. (2013)][9] in *Earthquake Spectra Journal* found you could get useful measurements (e.g. for emergency response) from networks of phones with a few tricks: * The more measurements the better. * Horizontal orientation is best. * Prefer high-friction phone covers. * Don't expect to get great data for small quakes. * Treat small groups of phones as arrays. * Don't use data for phones that fell off a table!
