Earthquake context

Earthquakes: magnitude, impact, and context

Earthquakes happen every day, but a count alone says little about consequence. This page separates routine seismic activity from signals that can change global context: magnitude, depth, official impact alerts, tsunami potential, significance, and unusual clustering. It explains what the dashboard would use without turning a worldwide summary into local safety advice.

Current evidence

Current earthquake signal

The current panel is reserved for normalized USGS observations that pass the production read boundary and retain their source times. It never fills missing records with a calm-looking zero.

Current earthquake observations are not exposed through the approved public read boundary. No live count, largest-event claim, or safety conclusion is shown until a current dataset can be verified.

Earthquake context

Why magnitude is only the beginning

Magnitude measures energy release on a logarithmic scale; it does not directly measure what people experienced. Depth, distance from communities, construction, terrain, and secondary hazards can make earthquakes with similar magnitudes produce very different outcomes. The dashboard therefore keeps official alert and significance fields separate from the magnitude itself.

Clustering is interpreted within a configured time window and does not imply that one earthquake caused another. A tsunami flag is also treated as a specific source-supported signal, not inferred from location. For urgent or local decisions, the relevant geological agency and civil-protection authority always outrank this global summary.

Methodology

Signals this page distinguishes

  1. Energy

    Reported magnitude is normalized without presenting it as a direct damage forecast.

  2. Observed impact

    Official alert, significance, felt, and tsunami fields add context only when the source supplies them.

  3. Time pattern

    A bounded cluster signal can raise attention while preserving each provider event identity.

Freshness state

How earthquake freshness works

Each event carries its occurrence time and provider update time. Once the configured usable window expires, the component becomes unavailable rather than silently carrying yesterday's conditions forward.
