1638 New Hampshire earthquake
The 1638 New Hampshire earthquake struck central New Hampshire on June 1, 1638 (Julian calendar).[2] It was the first major earthquake to strike New England following the start of European colonization. Modern analysis places its epicenter somewhere near what is now central New Hampshire, with an estimated magnitude between 6.0 and 7.0 mbLg.[1][3] This makes it the largest earthquake on record in New Hampshire and New England, and the second strongest in northeastern North America after the 1663 Charlevoix earthquake.
