Felt a shake when at Clark Air Base near Mt Pinatubo which
-- much later -- erupted and buried the base under ash.

BTW the Seabrook Nuclear Power Plant on the New Hampshire coast is on a fault line. And yes, they knew it before and during the construction. A concerned citizen's group told the NRC representatives at a public hearing!
Can you believe it ??!! On second thought it's only too easy to believe.
wow
NRC = a federal agency : Nuclear Regulatory Commission
