Visual summaries of the local seismic dataset built from USGS feeds and historical queries.
A high index means recent activity is high relative to the selected historical baseline. It does not mean that a larger earthquake is about to occur.
Daily counts, magnitude bands and regional rankings summarise the local dataset currently stored by Quake Pulse. They are useful for comparison and discovery.
Historical counts of small earthquakes are strongly affected by the evolution of detection networks. A higher count does not automatically mean the planet has become more seismically active.
For long-term analysis, consistent magnitude thresholds and clear time windows are more meaningful than raw totals.
Guides, explainers and practical reading to go beyond the live data.
Magnitude is only one part of the story. Depth, distance, local ground conditions and building vulnerability help explain why shaking can differ so much from one earthquake to another.

Earthquake-resistant design is not about making buildings immovable. It is about controlling forces, deformation and failure so people have a much better chance of staying safe.

Early-warning systems detect an earthquake after it starts and try to send an alert before the strongest shaking arrives. The difference between warning and prediction matters.
