Volcanic eruptions are attributable to magma rising by way of the Earth’s crust. This rising magma causes stress to construct up underground, finally inflicting an eruption. Throughout a volcanic eruption, lava (the identify for magma when it’s above floor), ashes, fuel, mud, and rocks are spewed out of the bottom (through Expatriate Healthcare). Volcanic eruptions can contaminate water provides, harm equipment, scale back visibility, make it exhausting to breathe, and irritate the eyes, pores and skin, nostril, and throat (through Prepared.gov).
There are two forms of volcanic explosions: effusive and explosive. Effusive eruptions are likely to have regular lava flows on the bottom, and are a lot much less prone to ship rocks flying. These eruptions can take a very long time to decrease, however often give these effected extra time to evacuate. Explosive eruptions are violent explosions that ship particles all over the place. These eruptions give little or no time to evacuate and might trigger heavier ash fall than effusive eruptions (through Britannica).
