Corrections
If a magnitude, location, depth, time, or derived figure on PlainQuake looks wrong, report it with enough detail to reproduce the page and compare it with the USGS ComCat record. The same process is documented in our editorial and corrections policy.
How to report
- Report. Email corrections@plainquake.com or use the contact page with the page URL, the figure that looks off, and what you think it should be.
- Source. Include a link to the USGS event page or ComCat query you think we should match.
- Scope. Say whether the issue is a raw catalog field, a derived ranking or distribution, or a stale vintage badge.
What happens next
We verify reports against USGS ComCat and correct confirmed issues in the canonical catalog or pipeline so affected pages update together. Material fixes are noted on the public data changelog. This site is an informational earthquake-data reference, not a warning system or emergency service.
