The measured length of the fault is approximately 350 km and is the longest fault in Guatemala. Motion of the fault and others in the plate boundary have formed north–south trending grabens across the region that show evidence of counter-clockwise rotation over time. Guatemala City lies in one of these grabens, which may contribute to 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.
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 ...
Bathymetry of the northeast corner of the Caribbean plate showing the major faults and plate boundaries; view looking south-west. The main bathymetric features of this area include: the Lesser Antilles Volcanic Arc; the old inactive volcanic arc of the Greater Antilles (Virgin Islands, Puerto Rico, and Hispaniola); the Muertos Trough; and the Puerto Rico Trench formed at the plate boundary ...
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.
To map the subduction zone, researchers at sea performed active source seismic imaging, a technique that sends sound to the ocean floor and then processes the echoes that return. The method is ...
New satellite images show a significant fault line stretching through a city near the epicentre of Turkey’s deadly earthquake. A vast fault line rupture in Nurdagi is seen cutting across a ...
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
