The Japan Median Tectonic Line is visible in forms of several outcrops and fault saddles in Ina city, Ōshika village, and Iida city in southern Nagano Prefecture. [9] The historic Akiha Kodo pilgrimage route ( Japan National Route 152 ) between Suwa-taisha shrine in central Nagano Prefecture and the Akihasan shrine in Shizuoka Prefecture ...
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
Fault lines are fractures between blocks of rock in the Earth’s crust, the layer closest to the surface. These lines allow tectonic plates to move and earthquakes occur when two plates slide ...
Map depicting the extent of the Ramapo Fault System in New York, New Jersey, and Pennsylvania. The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. [1]
Faults may also displace slowly, by aseismic creep. [2] A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4]

The San Jacinto Fault Zone and the San Andreas Fault (SAF) accommodate up to 80% of the slip rate between the North American and Pacific plates.The extreme southern portion of the SAF has experienced two moderate events in historical times, while the SJFZ is one of California's most active fault zones and has repeatedly produced both moderate and large events.
