Seismological Characterization of the 2021 Yangbi Foreshock‐Mainshock Sequence, Yunnan, China: More than a Triggered Cascade

Abstract: Foreshocks are known as smaller earthquakes preceding the large mainshock (Jones & Molnar, 1979). Due to the neighboring location and temporal correlation, foreshocks are considered as a possible precursory phenomenon, for example, the success prediction of 1975 M w 7.0 Haicheng earthquake largely relies on the ∼1-day foreshock activity (Wang et al., 2006). Traditionally, two end-member models are proposed to explain the triggering relationship between the foreshocks and mainshock (Dodge et al., 1996): the cas… Show more

“…While we did not find any direct evidence for fluid involvement, we argue that high‐fluid pressures could help in driving the Yushu foreshock‐mainshock‐aftershock sequence. This study, together with other recent studies (e.g., Doi & Kawakata, 2012; Lei et al., 2021; Liu et al., 2022; Wu et al., 2014; T. Yang et al., 2022; Yao et al., 2020; Zhou et al., 2022) indicates that foreshock sequences could be complex, and it is challenging to use them as possible warnings for upcoming large events.…”

“…∆CFS has been used to assess seismicity rate changes and aftershock distributions (e.g., Toda & Stein, 2022), to infer earthquake interactions (e.g., Ellsworth & Bulut, 2018; Stein et al., 1997; Zhou et al., 2022), and to examine advances or delays in the occurrence of future earthquakes (e.g., Toda & Stein, 2020). To investigate the ∆CFS imparted by the Luding earthquake, we employed the slip distribution of our preferred finite‐fault model (Model–2) and carried out the calculation using the Coulomb 3.3 software (Toda et al., 2011).…”
