Hank McCarl, W4RIG writes on Cape Ann ARA list:
The seismograph [at the Cape Ann Amateur Radio Association] at 6 Stanwood Street [in Gloucester] reported a 2.7 magnitude earthquake with epicenter at East Kingston, NH just north of Amesbury, MA at 9:28 AM on Thursday February 15, 2018.
This quake was also detected by Stan Stone [W4HIX] with his seismograph in Lanesville. Nice to know that our own MAGLO is operating as part of the USGS Netquake program.
