摘要

Before the M (L) 6.6 Meinong earthquake in 2016, intermediate-term quiescence (Q (i)), foreshocks, and short-term quiescence (Q (s)) were extracted from a comprehensive earthquake catalog. In practice, these behaviors are thought to be the seismic indicators of an earthquake precursor, and their spatiotemporal characteristics may be associated with location, magnitude, and occurrence time of the following main shock. Hence, detailed examinations were carried out to derive the spatiotemporal characteristics of these meaningful seismic behaviors. First, the spatial range of the Q (i) that occurred for similar to 96 days was revealed in and around the Meinong earthquake. Second, a series of foreshocks was present for similar to 1 day, clustered at the southeastern end of the Meinong earthquake. Third, Q (s) was present for similar to 3 days and was pronounced after the foreshocks. Although these behaviors were recorded difficultly because the Q (i) was characterized by microseismicity at the lower cut-off magnitude, between M (L) 1.2 and 1.6, and most of the foreshocks were comprised of earthquakes with a magnitude lower than 1.8, they carried meaningful precursory indicators preceding the Meinong earthquake. These indicators provide the information of (1) the hypocenter, which was indicated by the area including the Q (i), foreshocks, and Q (s); (2) the magnitude, which could be associated to the spatial range of the Q (i); (3) the asperity locations, which might be related to the areas of extraordinary low seismicity; and (4) a short-term warning leading of similar to 3 days, which could have been announced based on the occurrence of the Q (s). Particularly, Q (i) also appeared before strong inland earthquakes so that Q (i) might be an anticipative phenomenon before a strong earthquake in Taiwan.
