The source matters, too.
Observations, not predictions
GEOLATIDO uses ComCat, the event catalogue published by the U.S. Geological Survey (USGS). We show recorded observations; we do not forecast earthquakes or issue emergency alerts.
Which data we use
The global 30-day feed is fetched every five minutes. Only earthquake-type events with valid coordinates and times are included. Missing magnitudes are retained without imputation. Failed requests preserve the last valid download and its age is shown.
Catalogue time and viewer dates use UTC. Publication occurs after an event happens. USGS may subsequently revise locations, magnitudes and depths.
Reading the maps
Point size varies with magnitude and colour with depth: below 70 km, 70 to below 300 km, and 300 km or more. Magnitude does not equal intensity or damage.
Concentration groups events into one-degree latitude by one-degree longitude cells. Physical cell areas differ. This counts observations; it does not measure hazard or exposure.
Chile vicinity
The initial view covers longitudes 80° W to 65° W and latitudes 56° S to 17° S. It includes offshore areas and neighbouring territories; it is not an administrative boundary. North, central and south bands are separated at 27° S and 38° S.
Comparisons and coverage
Charts share the same filters. Histograms label bins and the time series includes days with zero events. Counts should not be compared as risk: recording coverage and detection thresholds differ between networks. Original magnitude types are retained per event and in downloads.
