How many natural hazard events this site recorded in each country, each month, across every source it follows. Free to download and reuse under CC BY 4.0, with no key and no registration.
Read this before you use the numbers
These are counts of what this site RECORDED, not counts of what happened. Coverage is uneven: a country with dense seismic instrumentation produces more recorded earthquakes than one without, at the same real rate. Read them as a record of monitoring, not as a measurement of the world.
Events recorded per month
Worldwide, all hazard types and all sources combined. The rise and fall here is mostly this site adding and stabilising feeds, which is exactly the point of the warning above.
The files
Events per country per month
How many events of each hazard type this site recorded in each country, by calendar month, across every source it follows.
Why it exists: The cross-source series. Seven feeds disagree about hazard names, severity scales and how a country is decided; this is the reconciled result, and it exists nowhere else.
Grain: One row per month, country, hazard type and severity level.
Columns:
month, country_iso2, country, hazard, severity, events
Events per hazard per month, worldwide
The same series without the country dimension: a worldwide monthly count for each hazard type.
Why it exists: Small enough to chart directly and the right table for a question about seasonality rather than geography.
Grain: One row per month, hazard type and severity level.
Columns:
month, hazard, severity, events
Sources and what each one covers
Every feed this site follows, what kind of statement it publishes, whether it rates severity itself, and what it will not tell you.
Why it exists: The provenance table. Any analysis of the counts above needs it, because a detection and a warning are not the same kind of row.
Grain: One row per source.
Columns:
source_key, name, class, rates_severity, limitation
Licence
CC BY 4.0 — read the terms. Use them commercially, modify them, redistribute them; credit World Natural Disasters and link back.
The licence above covers the counts, which this site computed. It does not cover the underlying observations: those belong to the agencies named on each row, and their own terms apply if you go to them directly. The agencies are listed on data sources, with their current status.
How current it is
Recomputed on request from live data. Earthquake and weather sources are re-synced every 2 minutes; satellite and humanitarian sources every 15.
The series begins in 2002-01, which is when this site started recording — not when the world started producing events. Files are capped at 50,000 rows; a truncated file says so in its own last line rather than ending quietly.
If you want it live instead
These files are snapshots. For the current feed use the free JSON and GeoJSON API — no key, CORS enabled, OpenAPI spec published. For a page rather than data, the embeddable widget takes one block of HTML.
