Pacaya Volcano Facts: Read About This Dangerous Threat To Guatemala
Gallery
The Pacaya is amongst the most active volcanoes, located in Guatemala City.
The Pacaya volcano is a popular tourist attraction in Guatemala, but it's also a dangerous threat to the country. This volcano is very active and has caused destruction and death in the past.
The active volcano in Guatemala city has erupted frequently since 1565, and it is considered to be a very dangerous threat to the people of Guatemala.
The Pacaya volcano is located in the Pacific Ring of Fire, which encircles the basin of the Pacific Ocean. This region is well-known for being a hotbed of seismic activity, and it contains around 75 % of all active volcanoes on Earth.
There have been three major eruptions during recorded history; one in 1965, another in 1969, and the third one in 1976. The volcano erupted for 23 days during the first major eruption, and it lasted for six months during the second event.
After the 1999 event, several more eruptions followed over the next couple of decades. The most recent three were in 2014, 2015, and 2017.
The eruptions also produced lavas that traveled as far as the town of El Rodeo during one event in 2010, which caused property damage to several homes and farms in the area.
In this article, we will discuss the history of the Pacaya volcano, its eruptions, and the danger it poses to the people of Guatemala City.
History Of Pacaya Volcano
Little is known about Pacaya's early historic eruptions; nonetheless, Pacaya has exploded at least 23 times since 1565, with the biggest eruption occurring in 1775.
The Pacaya volcano is located in the Pacific Ring of Fire, which encircles the basin of the Pacific Ocean. The Ring of Fire is a horseshoe-shaped geological region that runs along the Pacific Ocean. It is made up of 45,000 miles of volcanoes and earthquake zones.
There have been three major eruptions during recorded history; one in 1965, another in 1969, and the third one in 1976.
The volcano erupted for 23 days during the first major eruption, and it lasted for six months during the second event. After the 1999 event, several more eruptions followed over the next couple of decades. The most recent three eruptions occurred in 2014, 2015, and 2017.
Formation Of Pacaya Volcano
The Pacaya volcano was formed by a period of volcanic activity that took place between two million years ago and 500,000 years ago.
Pacaya is a 2,552-meter-high complex volcano formed of an ancient stratovolcano comprising domes, flows, and tephra as well as a newer basaltic stratovolcano. The majority of the complex was produced within the last 23,000 years.
The Pacaya complex is part of a sequence of volcanoes that runs along Guatemala's Pacific coast. The entire chain was generated tectonically by the sinking of the Cocos Plate beneath the Caribbean Plate. The mountain is situated near the southern edge of a large caldera developed during the Pleistocene period.
Height And Size Of Pacaya Volcano
The Pacaya volcano is a stratovolcano that measures around 500 meters high and has an elevation of 2352 feet above sea level.
The volcano is located in the southern part of Guatemala, near the city of Antigua. It is approximately 25 miles south-southwest from Guatemala City.
Pacaya Volcano Eruptions
The first major eruption of the Pacaya volcano occurred in 1965. These explosions lasted for 23 days, and they produced a lava flow that traveled as far as the town of El Rodeo.
The second major eruption of the volcano occurred in 1969. This event lasted for six months, and it produced a lava flow that also traveled as far as the town of El Rodeo.
The third of the major eruptions of the volcano occurred in 1976. This event lasted for six months, and it produced a lava flow that again, traveled as far as the town of El Rodeo.
There was an event in 1999 that was not considered to be a major eruption, but it did produce some lava flows. The most recent major eruption occurred in 2010. This event lasted for six months and produced a lava flow that traveled, like the previous eruptions, as far as the town of El Rodeo.
During an explosion in 1998, blocks and craters were spread all over the surrounding areas, which caused the Guatemala City Airport to close because of ashfall. In reality, the airport was closed twice that same year owing to ash, and again in 2000.
Even if the volume of ash engaged was small, it can have a significant influence on aircraft engines, and hence only an mm of ash can result in airport closure.
In December 2007, the volcano saw modest strombolian activity from the open summit crater of Pacaya.
After the 1999 event, several more eruptions followed over the next couple of decades.
2010 was a strombolian eruption and the 2015 eruption was also minor, but the 2017 eruption lasted for six months.

Pacaya is Central America's largest post-caldera volcano and has been one of the most active volcanoes for the last 500 years.
The Pacaya Volcano is a stratovolcano. One of the biggest dangers posed by the Pacaya Volcano is the potential for lahars.
The people who live near the Pacaya volcano are constantly living in danger from potential lahars and other volcanic hazards.
The volcano faces mildly explosive and effusive eruptions; strombolian activity, ash or lava fountaining, and lava flows from the summit crater. The volcano has been almost continuously active in the last centuries.
When did Pacaya last erupt?
The volcano's edifice crumbled around 1,100 years ago, resulting in a massive avalanche.
The Pacaya Volcano last erupted in 2017 and again in 2021.

What hazards are associated with Pacaya?
One of the biggest dangers posed by the Pacaya volcano is the potential for lahars.
Lahars are a type of mudslide that can be generated when water and volcanic ash mix together. The mixture can become very thick and flow down the slopes of the volcano at high speeds, potentially causing widespread damage to anything in its path.
The volcano is also known for its explosive eruptions, which can cause widespread damage. Additionally, the ash clouds produced by these eruptions can present a health hazard to those in the surrounding area.
