What the sequence shows

After the M 6.2 reference event, Quake Pulse counts 3 M4+ event(s) in the first 24 hours and 10 in the first 7 days. Fourteen-day M4.5+ activity is about 1.2× the average equivalent derived from the previous year. The largest secondary event is M 0.8 below the reference event.

Local historical context

Descriptive comparison with M4.5+ events observed in the same radius during the 365 days before the sequence.

M4.5+ events / 365 d276Average 14-day equivalent10.6Activity / baseline ratio1.2×

A ratio above 1 means denser M4.5+ activity than the average equivalent derived from the previous 365 days. It is not a risk measure or a forecast.

Interpretation

Explore clusters of M4.5+ events observed around significant earthquakes. These clusters are descriptive and are not presented as earthquake predictions. Historical small-earthquake detection varies through time. Long-term comparisons are most robust at higher magnitude thresholds.
