Guatemala is located in a complex tectonic setting influenced by the interaction of three tectonic plates: the North American plate to the north, the Caribbean plate to the south, and the Cocos plate to the south–west.

What type of plate is the Caribbean plate?
oceanic tectonic plate
The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America.
What caused the Guatemala earthquake 1976?
The locations of surface ruptures and the main shock epicenter indicate that the disastrous Guatemala earthquake of 4 February 1976 was tectonic in origin and generated mainly by slip on the Motagua fault, which has an arcuate roughly east-west trend across central Guatemala. Fault breakage was observed for 230 km.
What kind of boundary is the Motagua Fault?
transform boundary
The Motagua and Polochic faults in Guatemala are considered the continental part of the left-lateral transform boundary between the Caribbean and North America plates.
Does Guatemala have volcanoes?
Lying between the Caribbean Sea and the Pacific Ocean, Guatemala is a mountainous nation that is home to 37 awe-inspiring volcanoes. These make up part of the Central American Volcanic Arc: a long chain of volcanoes that stretches down the Central American Isthmus.
Are tectonic plates?
Tectonic plates are pieces of Earth’s crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).
What tectonic activity causes volcanoes in Mexico and Guatemala?
The imposing volcanoes of central Mexico and Guatemala—including Popocatépetl, which looms on the horizon in Mexico City—owe their existence to the subduction of the Cocos Plate beneath the North American Plate at the brisk clip of three inches per year.
What is the name of this tectonic plate?
The seven major plates include the African, Antarctic, Eurasian, North American, South American, India-Australian, and the Pacific plates. Some of the minor plates include the Arabian, Caribbean, Nazca, and Scotia plates. Here is a picture showing the major tectonic plates of the world.
Is the Caribbean plate convergent divergent?
The South American plate lies mostly to the South. This is a transform plate boundary, and the Cocos plate lies to the west and this is a converging plate boundary. The northern boundary of the Caribbean plate with the North American plate is a transform plate boundary, as seen in the image above.
How many people died in the 1976 earthquake in Guatemala?
23,000 fatalities
The earthquake struck during the early morning (at 3:01 am, local time) when most people were asleep. This contributed to the high death toll of 23,000. Approximately 76,000 were injured, and many thousands left homeless.

Is Guatemala on a fault line?
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.
What natural disasters are common in Guatemala?
Guatemala is exposed to multiple natural hazards, including earthquakes, volcanic eruptions (and all their associated hazards, such as ash, lava flows, pyroclastic density currents and lahars), tsunamis, landslides, floods, droughts, ground collapse, tropical storms and hurricanes, extreme temperatures, and forest
What type of plate boundaries exist in South America and Antarctic plates?
The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the
What type of plate boundary is the South American plate and Nazca Plate?
continent convergent boundaries
Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Range) and subduction of the Juan de Fuca Plate under North America (creating the mountains Garibaldi, Baker, St.
What type of plate boundary is between the Antarctic Plate and the Pacific plate?
The southern side is a divergent boundary with the Antarctic Plate forming the Pacific–Antarctic Ridge.
What type of volcanoes are in Guatemala?
Fuego is a stratovolcano or composite volcano. Its steep, conical shape, which is typical of this type of volcano, can be seen from the capital, Guatemala City, 44km (27 miles) south-west of Fuego’s summit.
What active volcanoes are in Guatemala?
Guatemala has at least 37 volcanoes, the most in the region. Fuego, Pacaya, and Santiaguito are active volcanoes.
What volcano erupted in Guatemala?
Two of Guatemala’s active volcanoes, Fuego (upper left) and Pacaya (lower right) were erupting when the ASTER nighttime thermal infrared image was acquired on March 5, 2021. Pacaya’s most recent eruption began Wednesday, with several lava flows and ash eruptions; surrounding villages were ordered evacuated.
Where are the tectonic plates?
In plate tectonics, Earth’s outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.
Where are all the tectonic plates located?
lithosphere
The outermost part of Earth’s structure is known as the lithosphere. The lithosphere consists of the crust and small portion of the upper mantle. The lithosphere is divided into a number of tectonic plates. These plates move and interact with one another, driven by convectional forces within the Earth.
