This is where the majority of the population lives, builds roads and pursues industrial and agricultural production activities. CENTRAL AMERICAN VOLCANIC BELT - Central American volcanoes extend along a subducting plate boundary through Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and into Panama. The volcanic products from these eruptions range in composition have SiO{2} mode of 70 wt.%. This is very important at the time of making hazard and risk estimates, especially when the limited monetary resources of Central American countries are known. The Central American Volcanic Arc (often abbreviated to CAVA) is a chain of volcanoes which extends parallel to the Pacific coast line of the Central American Isthmus, from Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and down to northern Panama.

Students and scientists beginning research in the region will find in this book a useful context and introduction to the region's scientific leaders. Volcanic arcs are formed when two tectonic plates collide in a subduction zone causing one to bend and slide underneath the other, creating a curvature in the Earth's mantle and magma chambers in the crust. The Central American Volcanic Arc, usually abbreviated as CAVA, is a series of volcanoes that extend from Guatemala to Northern Panama, running parallel to the Pacific coastline.

These make up part of the Central American Volcanic Arc: a long chain of volcanoes that stretches down the Central American Isthmus. Unfortunately, current plate reconstructions fail to explain many geologic constraints in the published literature. There are two ways to the volcano’s peak. The resulting data consisted of tremor and thousands of discrete events associated with ongoing outgassing. Where possible, individual events were identified and located. They were found to be high in the edifice near the vent. From time to time, the relatively gentle activity is interrupted by stronger, more destructive eruptions.

The currently most active volcanoes in Central America include Santa María with its flank cone Santiaguito, Pacaya and Fuego in Guatemala, and Arenal in northwestern Costa Rica. "The Panama segment of the arc is unusual, with almost no volcanic activity despite active subduction." Despite a substantial amount of rain that made some of the backcountry work difficult, and quite a bit of driving time to get to the remote locations, the team managed to collect samples from 25 additional sites, each with co-localized . Once considered a gateway to hell, the Central America Volcanic Arc is now a playground for adrenaline junkies and volcano enthusiasts from around the world. Tourists who climb to the summit can relish panoramas of the Pacific Ocean on one side. Though many of them are dormant, there is a number of them that are actively discharging lava and ash into the environment. It is a relatively easy 1.5- to 2-hour trek through forests.

Subduction of the Cocos Plate under the Caribbean Plate results in active volcanism in Central America. Pacaya Volcano is an active composite volcano located in southern Guatemala, about 30 km from the nation's capital, Guatemala City. Its youthful magma reservoir is immature, characterised by incomplete interruptions of magma evolution and irregular quiescent degassing processes, impeding that a regular eruption cycle establishes. features of the Central American volcanic arc can help constrain the element flux through an arc system. The Central American volcanic arc is generated by sub- duction of the Cocos plate at the Middle America Trench along the southwestern margin of the Caribbean plate.
