San Francisco earthquake
The NOAA HazEL catalogue records an earthquake at San Francisco, California.

HazEL ID 2768, authority year 1906. Native reference #415 explicitly describes the California earthquake. Other quoted references differ over casualties and monetary damage; those figures are excluded.

- Kind of record
- Placed in a year. A source places this in one year. It is listed under that year; no day precision is invented.
How it is dated
- Date reference
- 1906, April
- How we use it
- Year-level placement is limited to the dated source entry.
The date reference is this project’s reading of the source’s date. It may give an era name, a reign or a calendar in a normalised form rather than in the source’s own words; the dating notes say what the source prints.
Dating notes from the research record
The authority's year 1906 maps directly to CE 1906. Examined all lines of noaaquake02.txt and noaaquake02-native.txt; matching row 6 and native reference #415 date the occurrence to April 1906. Original quotation begins at line 6, character 882.
File names and line numbers in these notes, and in the limits above, refer to the project’s retained copies of the cited sources. Names such as calendar_headers are the project’s calendar look-ups, and “the investigator” is the research step that prepared the record.
Sources and quoted text
Line and character numbers under “Location” refer to the project’s retained copy of the source. For database rows, “Edition” names the batch of rows that was fetched together.
