WebbVolcanic eruptions spew out lava, carbon dioxide (CO 2) ash and particles. Although CO 2 has a warming effect, average volcanic CO 2 emissions are less than 1% of emissions from current human activities. .Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. WebbLava domes grow by extrusions and intrusions of viscous magma often initiating from a central volcanic vent, and they are frequently defining the source region of hazardous explosive eruptions and pyroclastic density currents. Thus, close monitoring of dome building processes is crucial, but often limited to low data resolution, hazardous access, …
