英文摘要	Seismic quiescence or enhanced phenomena are anomalous changes against the background of normal seismic activity. Preliminary studies have found that earthquakes with a magnitude of ML >= 4 often occur at a low occurrence frequency before giant earthquakes in Tibet. This study analyzed the catalog of ML >= 4 earthquakes from 2008 to 2022 and examined the anomalous occurrence of ML >= 4 earthquakes preceding most ML >= 6 earthquakes. When the monthly occurrence frequency of ML >= 4 earthquakes was lower than 4 times over six consecutive months, the subsequent occurrence of ML >= 6 earthquakes was highly likely as evidenced by observations. The anomalous characteristics of low-intensity activities were analyzed as a medium-and short-term forecasting index for large earthquakes in the Tibetan area.
