What this page is5 rows held · newest sealed read 2026-10-13
- We caught USGS revising 5 Oregon earthquakes, out of 961 revisions we caught anywhere.
- In Oregon, the magnitude moved on 4 of them, the depth on 4, and the place on 1.
- We hold a dated copy of 96 separate Oregon events, out of 25,908 events across every region.
- Our oldest sealed copy is 23 Jun 2026 and our newest one is 13 Oct 2026. Reading was switched back on by a dated decision on 23 Aug 2026, after a pause, so this list can still grow.
- We hold two or more dated copies for 11,014 of 25,908 events, and a single copy for the other 14,894. Where we hold two copies you can see what changed between them; where we hold one there is nothing to compare it with. USGS publishes this history itself, including superseded versions, so we do not charge for it.
Real rows out of our sealed copies
These are rows we read out of dated copies we keep ourselves. The live source shows today only, so once a row moves, what it said before is gone from the place you would go to look.
Real revisions we caught in Oregon. 5 of 5 shown; the file you buy carries all 5. Numbers are printed exactly as USGS published them, long decimals and all. We do not round, because the value USGS actually put out is the whole point of the archive.

What this page cannot tell you
- We can only show a change between two of our own reads. USGS can revise an event whenever it likes, so if it changed a number and changed it back between two of our reads, we never saw it and it is not on this page.
- Each file we saved holds the last 24 hours of events, and our runs were about 24 hours apart, so two copies sealed on consecutive days usually share no event at all: only 56 of our 104 consecutive day pairs had one in common. A before and an after exists only where two runs landed closer together than usual.
- 14,894 of the 25,908 events we hold were caught on one day only. There is no second reading to compare them with, so they cannot show a revision.
- We ran on 14 Aug 2026, 15 Aug 2026, 16 Aug 2026, 17 Aug 2026 and the feed gave us nothing back, so there is no copy for those days. We say that rather than skipping over it.
- 4 days inside our range have no run at all: 4 Jul 2026, 15 Jul 2026, 22 Aug 2026, 23 Aug 2026.
- We hold what USGS published. We are not saying which reading is right. The current catalogue keeps only the later one.
- The region on this page is read off the place text USGS itself writes, such as “2 km W of Oceanside, Oregon”. We do not put an event in a region USGS did not name.
See the file we hold
You do not have to take our word for what is in the file. Here are 25 rows of the real thing, carrying all 7 of its columns, cut out of the dated copies we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.
- Open the 25 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
- The same 25 rows as JSONThe same rows again, laid out for reading with code.
Nothing on this page is for sale. The sample file is free to read, and so is every row on the page above it.
These 25 rows are a slice of the file, not the whole of it. What we cannot show you here is how far back it goes: the file goes back further than these rows do.
