火山类型火山是多种多样的，根据它们的活动情况可以分为死火山、休眠火山和活火山三大类。

死火山，指史前曾发生过喷发，但有史以来一直未活动过的火山。

此类火山已丧失了活动能力。

有的火山仍保持着完整的火山形态，有的那么已遭受风化侵蚀，只剩下残缺不全的火山遗迹、我国某某某某火山群在方圆约50平方公里的X 围内，分布着2个孤立的火山锥，其中狼窝山火山锥高将近120米。

休眠火山，指有史以来曾经喷发过．但长期以来处于相对静止状态的火山。

此类火山都保存有完好的火山形态，仍具有火山活动能力，或尚不能断定其已丧失火山活动能力。

如我国白头山天池，曾于1597年和1792年两度喷发，在此之前还有多次活动。

目前虽然没有喷发活动，但从山坡上一些深不可测的喷气孔中不断喷出高温气体，可见该火山目前正处于休眠状态。

活火山，指现代尚在活动或周期性发生喷发活动的火山。

这类火山正处于活动的旺盛时期。

如爪吐岛上的梅拉皮火山，本世纪以来，平均间隔两二年就要持续喷发一个时期、我国近期火山活动以某某岛大屯火山群的主峰七星山最为有名。

大陆上，仅95年在某某昆仑某某段于田的卡尔达西火山群有过火山喷发记录。

火山喷发形成了一个平顶火山锥，锥顶海拔4900米，锥高145米，锥体底直径642米，锥顶直径175米，火山口深56米。

应该说明的是，这三种类型的火山之间没有严格的界限。

休眠火山可以复苏，死火山也可以“复活〞相互间并不是一成不变的。

过去一直认为意大利的维苏威火山是一个死火山，在火山脚下，人们建筑起许多的城镇，在火山坡上开辟了葡萄园，但在公元79年维苏威火山突然爆发，高温的火山喷发物袭占了毫无防备的庞贝和赫拉古农姆两座古城，两座城市及居民全部毁灭和丧生。

火山喷发时，气体、岩浆、固体等物质向外排出的出口叫做火山口。

一般来说，中心喷发每次只有一个火山口，但绝大多数火山都是多次喷发。

以后的喷发有些是从原来的火山口喷出，但更多的是在其侧喷发，从而形成新的火山口，被称做寄生火山口。
