What is a lahar, and why are lahars commonly associated with eruptions of composite volcanoes? Webvolcanoes quiz. Explain why some volcanic eruptions are explosive and others are quiescent. Magmas with higher viscosities result in more explosive eruptions and magmas with lower viscosities result in less explosive, more quiescent eruptions. Higher viscosities prevent dissolved gases from escaping, so the gases build up more and more pressure ...
