Volcanology and geophysics

中美洲火山弧(CAVA)是世界上火山活动最活跃的地区之一，尤其是在加勒比海、北美和可可板块在危地马拉汇合的南端。这导致了一种不同寻常的火山线条，当你朝着弧形前进时，它变得更年轻，更具镁铁质。位于危地马拉西部的阿蒂特兰湖就是这些线条的最明显的例子，湖上发生了三次大型硅质喷发，南部火山口墙上有多个层状火山生长。在邻近的火山口Xela和Amatitlan上可以看到这种模式。

The Central American Volcanic Arc (CAVA) is one of the most volcanically active regions in the world particularly towards the southern end where the Caribbean, North American and Cocos plate meet together in Guatemala. This has resulted in an unusual lineament of volcanoes getting younger and more mafic as you travel towards the arc. Lake Atitlan which is located in Western Guatemala is the clearest example of these lineaments with three large silicic eruptions occurring at the lake as well as multiple stratovolcano growth on the southern caldera wall. This pattern is seen on the neighbouring calderas Xela and Amatitlan.
