Earthquake activity during 2014: a timeline showing magnitude of each event and cumulative number of events (arrows mark the onsets of the Biel, Frauenfeld, and Diemtigen sequences); b magnitude histogram. Removing events detected by supplementary algorithms and events associated with the two sequences results in 607 events in 2014 (blue curve in a), which is close to the average number of 541 events/year (horizontal dashed grey) over the last 12 years
