Abstract

The differences in the metrological support, problem statement, and practice of conducting measurements and using data in a typical physical experiment and geophysical monitoring are discussed. The strong difference in metrological support in these cases is consistent with the practice of using the results obtained. Due to the specific nature of the typical problem setting and use of geophysical monitoring data, the inevitable and poorly controlled errors in these data are relatively less detrimental to the use of the data than would be the case in typical physical surveys. Geophysical monitoring tools often track the behavior of highly nonequilibrium systems, often with a subcritical behavioral pattern, which leads to great variability in their behavioral pattern. Examples of false, but at the same time statistically significant anomalies are given. The features of using statistical approaches in the analysis of nonequilibrium systems with a subcritical nature of behavior are discussed; in this case, some standard statistical approaches may be incorrect.

论地球物理监测数据获取和使用的特殊性(兼谈A.V. Deshchervsky关于区域地球物理监测数据质量问题的文章)
讨论了在典型的物理实验和地球物理监测中进行测量和使用数据的计量支持、问题陈述和实践的差异。在这些情况下,计量支持的强烈差异与使用所得结果的实践是一致的。由于典型的问题设定和地球物理监测数据的使用的具体性质,这些数据中不可避免的和控制不良的错误对数据使用的危害相对小于典型的物理调查。地球物理监测工具经常跟踪高度非平衡系统的行为,通常具有亚临界行为模式,这导致它们的行为模式具有很大的可变性。给出了错误但同时具有统计意义的异常的例子。讨论了用统计方法分析具有亚临界性质的非平衡系统的特点;在这种情况下,一些标准的统计方法可能是不正确的。

期刊介绍: Seismic Instruments is a journal devoted to the description of geophysical instruments used in seismic research. In addition to covering the actual instruments for registering seismic waves, substantial room is devoted to solving instrumental-methodological problems of geophysical monitoring, applying various methods that are used to search for earthquake precursors, to studying earthquake nucleation processes and to monitoring natural and technogenous processes. The description of the construction, working elements, and technical characteristics of the instruments, as well as some results of implementation of the instruments and interpretation of the results are given. Attention is paid to seismic monitoring data and earthquake catalog quality Analysis.
