Lava domes in the crater of Mount St. Helens

In volcanology, a lava dome or volcanic dome is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano.

Lava Domes



Introduction

Lava domes, which may also be referred to as volcanic domes, are common features in volcanic regions throughout the world. Lava domes can come in many shapes and sizes, and while they may not be quite as spectacular as their explosive or flowing counterparts, they are often still an awe inspiring sight to see. The purpose of this page is to provide a brief introduction to lava domes, which will by no means be entirely comprehensive. In fact, even today, there is still much unknown about lava domes and what they can potentially reveal about volcanic systems.
Lava domes are formed by viscous magma being erupted effusively onto the surface and then piling up around the vent. Like lava flows, they typically do not have enough gas or pressure to erupt explosively, although they may sometimes be preceded or followed by explosive activity. However, unlike lava flows, the lava that forms domes is often to thick and sticky to flow very far, and thus instead pile up thick and high around the vent.
