Document Summary

Geo1111 - lecture 8 - volcanoes part 2. Hot spring: hot water that comes up to the surface of the earth. Fumaroles: gases that comes out of a vent at the surface of the earth. Geysers: when hot springs allow steam to accumulate, the water comes up to the surface in a eruption. https://www. bgs. ac. uk/research/energy/geothermal/ Pyroclastic flow: fast, explosive, dangerous and widespread; Gas emissions: hydrogen chloride, hydrogen sulfide, hydrogen fluoride and carbon dioxide. Lahar: fast mudflow of water (any source and consistency) and tephra. Happens during eruption or after (up to a few years); Debris avalanche/flow: unconsolidated volcanic material moving downward; Tsunami: caused by flows, avalanche, landslides or collapsing caldering that fall into water; Flooding: caused by flows breaking dams and rerouting rivers as well as melting glaciers; Atmospheric events: solid materials and gases reflect solar materials which causes the temperature to drop; Greenhouse gas: they make the heat stay in the atmosphere which causes higher temperatures; https://en. wikipedia. org/wiki/geologic_temperature_record.
