This zigzag type of fault trace is known as "mole track", which is best developed in hard-packed, brittle surface materials. The Motagua Fault has been responsible for several major earthquakes in Guatemala's history, including the 7.5 M w Guatemala 1976 earthquake, and is also notable for its significant visible fault trace.

A map of Guatemala. Guatemala is mountainous, except for the south coastal area and the vast northern lowlands of Petén department. The country is located in Central America and bounded to the north and west by Mexico, to the east by Belize and by the Gulf of Honduras, to the east by Honduras, to the southeast by El Salvador, and to the south by the Pacific Ocean.

Along the Motagua Fault trace (1976 Guatemala earthquake) where it crosses the Gualán soccer field. This zigzag type of fault trace is known as "mole track", which is best developed in hard-packed, brittle surface materials. The San Andreas fault trace runs along the base of the Temblor Range of mountains near Bakersfield, California. (The ...
Plate tectonics in the Americas Motagua Fault (green line) and the Middle America Trench (pink line). Earthquakes are relatively frequent occurrences in Guatemala. [1] The country lies in a major fault zone known as the Motagua and Chixoy-Polochic fault complex, which cuts across Guatemala and forms the tectonic boundary between the Caribbean plate and the North American plate.
The Motagua Fault, which crosses through Guatemala, is a transform boundary between the southern edge of the North American plate and the northern edge of the Caribbean plate. New Zealand's Alpine Fault is another active transform boundary. The Dead Sea Transform (DST) fault which runs through the Jordan River Valley in the Middle East.
Between Honduras and Guatemala, the frontier is formed by the Sierra de Merendón. A few of the streams of the Pacific slope actually rise in the highlands pushing through the Sierra Madre at the bottom of deep ravines. A large river, the Chixoy or Salinas River, flows northwards towards the Gulf of Mexico.
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] A fault zone is a cluster of parallel faults.
