地震震级是监视、研究和预报地震的主要地震参数之一。震级的精确程度直接关系到地震研究工作的质量。在地震震级测定工作中,由于各种因素的影响,存在着不少问题;就烟台台网而言,同一地震不同台站所测震级有很大出入,最大相差可达一级。即使同一台站对于不同地区,以及同一地区不同时期的地震所测震级也有偏高或偏低的现象。为了解造成这种情况的原因和寻求解决的办法,本文就1979年7月以来烟台台网(烟台、莱阳、长岛、蓬
Earthquake magnitude is one of the major seismic parameters for monitoring, studying and forecasting earthquakes. The magnitude of the magnitude is directly related to the quality of seismic research. In the earthquake magnitude measurement work, due to various factors, there are many problems; in terms of Yantai network, the magnitude of the same earthquake at different stations measured a great discrepancy, the maximum difference up to one. Even the same station for different regions, as well as different periods of the same region earthquake magnitudes are also measured high or low phenomenon. In order to understand the reasons for this situation and the way to seek solutions, this article has been on Yantai network since July 1979 (Yantai, Laiyang, Long Island, Punta
