Earth:Sandwich Fault Zone
From HandWiki
Short description: Fault Zone in Illinois, USA
The Sandwich Fault Zone is a fault zone that runs northwest from Oswego to Ogle County, transecting Lee County in Northern Illinois. The fault has generally not been active, although a minor earthquake was reported in 2002 and 2010.[1] On July 15, 2024, at 0253hrs CST a 3.4 magnitude earthquake was recorded with an epicenter roughly 2 km North West of Somonauk, Il. It has a largely 400 to 600-foot vertical displacement, although parts can reach up to an 800-foot displacement, and is likely a configuration of several smaller faults, varying in both direction and displacement.[2][3]
