    • A method or system for detecting a seismic event includes detecting a primary wave of a seismic event using at least one sensor at a measurement location; using at least one parameter of the detected primary wave to determine an estimated peak ground intensity at the measurement location without determining the magnitude of the seismic event; determining an epicenter of the seismic event; and estimating the intensity of the seismic event at a specified location using the determined estimated peak ground intensity and the distance of the specified location from the epicenter. The epicenter can be determined using sensors at a single location. A noise detection system can filter out detected signals that correspond to local vibrations rather than seismic events.
    • 一种用于检测地震事件的方法或系统包括:在测量位置使用至少一个传感器检测地震事件的主波; 使用所检测到的主波的至少一个参数来确定测量位置处的估计的峰值地面强度,而不确定地震事件的大小; 确定地震事件的震中; 以及使用所确定的估计的峰值地面强度和指定位置距离震中的距离来估计在指定位置处的地震事件的强度。 可以使用单个位置的传感器确定震中。 噪声检测系统可以滤除与局部振动相对应的检测信号,而不是地震事件。
