They are normally located above subduction zones and have felsic / intermediate magmas which produce lavas such as rhyolite / andesite. Viscous lava, ash, tephra and pyroclastic flows build up a steep sided cone with a crater(s) at the summit. ]]> 2017-11-08 02:04:03 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/204649829 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/204651080 2017-11-08 02:12:34 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/204651080 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/204651523 Japan]]> 2017-11-08 02:15:28 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/204651523 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/204653022 Very hot, fluid lava erupts, being thrown into the air as fire fountains, then landing near the vent forming spatter cones.

The eruptions may be violent. ]]> 2017-11-08 02:27:31 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/204653630 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/204654010 Vulcanian eruptions produce ash clouds and tephra in addition to pyroclastic density currents, which is a mixture of rock, gas and hot ash that flows in a manner very similar to fluids. The tephra from these flows is generally spread out over larger areas than the tephra emitted during Strombolian eruptions. Generally, the pyroclastic rock will create a volcanic cone made of ash and the resulting ash will cover a large area surrounding the volcano. These eruptions are caused by either a lava dome rupturing or when a plug of the lava from a volcanic conduit fragments and explodes.]]> 2017-11-08 02:30:20 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/204654010 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/204654299 The most violent eruptions caused as gassy and viscous magmas are released. The combination releases a huge amount of energy, which will create an eruption column which will contain ash, gas and could rise up to an altitude of 50 kilometers at very high speeds.]]> 2017-11-08 02:32:00 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/204654299 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/204654758 The lava or magma will interact with water in an explosive manner.]]> 2017-11-08 02:35:22 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/204654758 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/209190699 Volcanic Explosive Index]]> 2017-11-21 17:21:59 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/209190699 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/230754864 A broad, domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava.]]> 2018-02-12 18:36:01 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/230754864 bsnellin https://padlet.com/bsnellin/jn5x8v6jroso/wish/230756123 Some of the basalt is only moments old!]]> 2018-02-12 18:38:00 UTC https://padlet.com/bsnellin/jn5x8v6jroso/wish/230756123
