Global Earthquake Feed Snapshot

Contents

The download contains the populated data, a field dictionary, source metadata, reuse terms, a change log and file digests. It contains no scripts, libraries, executables or conversion tools.

Coverage

Complete retrieved all_month feed. The 30-day coverage window is defined by USGS, not selected by Arcomm. Detection and reporting are not globally uniform; events can be revised or removed. This is a dated snapshot, not a live alert service.

Read the data

JSON tables are arrays of records. GeoJSON files are FeatureCollections, with data fields under each feature’s properties. data-dictionary.json defines the fields, units, nulls and observed types. metadata.json supplies primary keys and source hashes. Preserve identifiers as text and distinguish missing values from zero.

Example record

This is an actual record from the data. For map layers, the example shows properties; the downloaded GeoJSON also contains the complete geometry.
