So I'm researching for my Nanowrimo novel. And found this--on October 7, 1902, Guam was rocked by more than 180 earthquake shocks! Reported in New Zealand news.
[My code isn't working so I'm having trouble linking.]
It's from the Wanganui Herald, Volume XXXVI, Issue 10768, 8 October 1902, Page 3 (try this and put in Guam earthquake for your search term).
Not relevant for the time period I'm hoping to write about, but a bit interesting.
