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，特别是加勒比海、北美和科科斯板块在危地马拉交汇的南端。这导致了一种不寻常的火山轮廓，当你向弧移动时，它会变得更年轻，更神秘。位于危地马拉西部的阿蒂特兰湖是这些地貌最明显的例子，湖上发生了三次大规模的硅喷发，南部破火山口壁上也有多个层状火山生长。这种模式在邻近的西拉火山口和阿玛蒂兰火山口上也可以看到。

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.
