Unusual months1
- Counts
- Earthquakes of magnitude 5 or more anywhere in the world in a month, UTC, as the US Geological Survey's catalogue counts them (event type earthquake, so mine blasts and the like are left out). The two newest months are asked again every day: the Survey reviews events and can add, drop or re-rate one, and the record keeps the revision. Counted from January 2010.
- Why it is here
- The planet has a magnitude 5 earthquake several times a day, and some months have half again as many as others.
- Cadence
- Monthly. The Survey posts a large quake within minutes and reviews it within days; a month prints seven days after it ends. Newest complete month Oct 2026. Read Nov 13, 07:40 UTC.
- Baseline
- The prior 24 months, 12 needed.

Asked often
- How many magnitude 5 earthquakes happen each month?
- The world had 223 earthquakes of magnitude 5 or more in Oct 2026, as the US Geological Survey's catalogue counts them.
- Where does the $BIGQUAKE number come from?
- Tickerz reads it from US Geological Survey, ComCat earthquake catalogue, FDSN event count service. Monthly. The Survey posts a large quake within minutes and reviews it within days; a month prints seven days after it ends. Each number is kept as it was first published, with a timestamped proof, and any later revision is shown beside it.
- Can I download the $BIGQUAKE data?
- Yes, free and with no key: the full history as JSON at https://tickerz.com/api/indices/bigquake and every period as CSV at https://tickerz.com/api/indices/bigquake/history.csv.

Resolution
- Index
- $BIGQUAKE Big earthquakes worldwide. Rulebook v0.2, 2026-10-04.
- Prints
- Monthly. The Survey posts a large quake within minutes and reviews it within days; a month prints seven days after it ends. The newest complete month is on the record after the daily proof at 12:40 UTC.
- As first published
Oct 2026 is not timestamped yet. The daily proof at 12:40 UTC adds it.
The number as first published is final for settlement. A revision by the source is shown beside it and never replaces it.
- Fallback
- A month prints seven days after it ends. If the count service answers 0 or fails, the month stays open. A month the Survey never answers is void.
- Precision
- Whole earthquakes of magnitude 5.0 or more, UTC month, event type earthquake.
- Cost to move
- Not possible. Nobody makes an earthquake.
- Grade
- reference. The US Geological Survey's own catalogue count, public domain. A review can move an event across magnitude 5 after the month prints; the record keeps the revision.
- For a rulebook
- Settle on the number Tickerz first recorded for $BIGQUAKE for the month named in the contract, published at tickerz.com/x/bigquake and in GET /api/indices/bigquake, timestamped daily in Bitcoin with OpenTimestamps.
