已经开发了一个计算机程序，用于在单个地震轨迹上自动探测和定时地震。该程序在线运行，并且足够简单，预计可以在现场应用的廉价低功耗微处理器中工作。在用地震模拟磁带进行的测试中，该程序正确地识别并在0.05秒内确定了大约70%的地震事件，而在网络运行中通常是定时的。该程序评估其选择的准确性，其估计似乎相当可靠。该算法目前在一台16位微型计算机上运行，似乎与目前可用的微处理器兼容。
A computer program has been developed for the automatic detection and timing of earthquakes on a single seismic trace. The program operates on line and is sufficiently simple that it is expected to work in inexpensive low-power microprocessors in field applications. In tests with analog tapes of earthquakes, the program correctly identified and timed to within 0.05 sec about 70 per cent of the events which would normally be timed in operation of a network. The program evaluates the accuracy of its picks, and its estimates appear to be quite reliable. The algorithm is working at present in a 16-bit minicomputer and appears to be compatible with presently available microprocessors.
