'地震' articles by year and province, with sample precision.

1,768articles · precision 0.76

Key point

Of earthquake articles, 76% are actual reports, so they are usable as a source for historical seismicity catalogs. Articles without a province are assigned to Seoul, so regional comparisons need care.

Formula: Keyword count; province from a province name in the article, otherwise Seoul (observatory report).
How to read it: Sillok earthquake articles are a main source of the historical seismicity catalog (Lee & Yang 2006).
Caveats: Assigning articles without a province name to Seoul can misplace provincial reports.
