Volcano Formation in CDMX
The formation of the volcano in CDMX is a result of the region’s complex geological history. The volcanic activity in the area can be traced back millions of years, when the land was part of a volcanic belt known as the Trans-Mexican Volcanic Belt.
The Trans-Mexican Volcanic Belt is a major volcanic arc that extends across central Mexico, encompassing several active volcanoes, including the one in CDMX. This volcanic belt was formed by the subduction of the Cocos Plate beneath the North American Plate.
The subduction process occurs when one tectonic plate is forced beneath another. In the case of the CDMX volcano, the Cocos Plate, a dense oceanic plate, subducts beneath the lighter and larger North American Plate.
As the oceanic plate subducts, it starts to melt due to the intense heat and pressure within the Earth’s mantle. The molten rock, known as magma, rises towards the surface, creating a pathway through cracks and weaknesses in the Earth’s crust.
Over millions of years, multiple eruptions occurred, releasing lava, ash, and volcanic gases, which gradually built up the volcanic cone that we see today. The accumulation of these materials resulted in the formation of a stratovolcano, which is characterized by its steep slopes and cone-like shape.
The volcano in CDMX, known as Popocatepetl, is one of the most active volcanoes in Mexico. It stands at an impressive height of 5,426 meters (17,802 feet) and is located approximately 70 kilometers (43 miles) southeast of the city.
Popocatepetl is classified as a stratovolcano due to its composite structure, which is made up of layers of hardened lava flows, volcanic ash, and pyroclastic materials. It is characterized by a large crater at its summit, known as a caldera, which occasionally emits smoke and gases.
The volcano is also surrounded by several smaller volcanic vents and cones, evidence of its ongoing activity. Despite its activity, Popocatepetl is closely monitored by scientists and authorities to ensure the safety of the surrounding communities.
The formation and ongoing activity of the volcano in CDMX is a testament to the continuous geological processes at work and a reminder of the region’s dynamic nature.
