WebAug 23, 2024 · This paper presents a method that computes a timeseries representing the weighted correlation of small earthquake activity in the California region from 1950 to … Webthe weighted correlation of small earthquake activity in the California region from 1990-2024. Prior to major magnitude M > 7 earthquakes, the timeseries trends toward lower values. Just after the earthquake occurs, the timeseries increases suddenly in association with the earthquake, before resuming its gradual trend towards lower values.
