[[Lava|Lava flows]] from stratovolcanoes are generally not a significant threat to humans or animals because the highly [[Viscosity|viscous]] [[lava]] moves slowly enough for everyone to evacuate. Most deaths attributed to lava are due to related causes such as [[explosion]]s and [[asphyxia]]tion from [[toxic gas]].<ref name=":12">{{Cite web|title=Lava flows destroy everything in their path|url=https://www.usgs.gov/programs/VHP/lava-flows-destroy-everything-their-path|access-date=16 October 2024|publisher=United States Geological Survey}}</ref> [[Lava|Lava flows]] can bury homes and farms in thick [[volcanic rock]] which greatly reduces property value.<ref name=":12" /> However, not all stratovolcanoes erupt viscous and sticky lava. [[Nyiragongo]], near [[Lake Kivu]] in [[central Africa]], is very dangerous because its [[magma]] has an unusually low [[Silicate|silica content]], making it much less viscous than other stratovolcanoes. Low [[viscosity]] lava can generate massive [[lava fountain]]s, while lava of thicker viscosity can solidify within the vent, creating a [[volcanic plug]]. Volcanic plugs can trap [[volcanic gas]] and create pressure in the magma chamber, resulting in violent eruptions.<ref>{{Cite web|title=Eruption styles|url=https://www.bgs.ac.uk/discovering-geology/earth-hazards/volcanoes/eruption-styles/|access-date=24 October 2024|publisher=British Geological Survey}}</ref> Lava is typically between 700 and 1,200&nbsp;°C (1,300–2,200&nbsp;°F).<ref>{{Cite web|date=23 September 2024|title=Lava {{!}} Types, Composition, Temperature, & Facts {{!}} Britannica|url=https://www.britannica.com/science/lava-volcanic-ejecta|access-date=24 October 2024|website=Encyclopædia Britannica}}</ref>
