Is there accelerated crustal deformation before large earthquakes? A case study of strong intra-plate earthquakes in ChinaKey points
The existence of a detectable precursory phase of fault slip preceding major earthquakes has been a subject of ongoing debate for decades. A recent study (Bletery and Nocquet, 2023) demonstrated exponential acceleration of fault slip prior to large earthquakes. Conversely, (Hirose et al., 2024)…
