What the sequence shows

After the M 6.4 reference event, Quake Pulse counts 0 M4+ event(s) in the first 24 hours and 2 in the first 7 days. Fourteen-day M4.5+ activity is about 1.0× the average equivalent derived from the previous year. The largest secondary event is M 1.5 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 d106Average 14-day equivalent4.1Activity / baseline ratio1.0×

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.

Earlier events are shown as context only. They are not labelled precursors and should not be interpreted as predictive signals.

Detailed timeline

Dots represent M4+ events retained by the sequence detector. Dot size depends on magnitude.

Sequences are descriptive groupings based on spatial and temporal proximity. Quake Pulse does not establish a causal link between every event here and does not provide earthquake forecasts.

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.
