Tephra Accumulation Technique

Tephra is a fragmental material produced by a volcanic eruption regardless of composition, fragment size or emplacement mechanism.

When large amounts of tephra accumulate in the atmosphere from massive volcanic eruptions (or from a multitude of smaller eruptions occurring simultaneously), they can reflect light and heat from the sun back through the atmosphere, in some cases causing the temperature to drop, resulting in a temporary, "volcanic winter", climate change. In conjunction with the Volcano God Mode technique, the user can cause many volcanoes to erupt simultaneously. Tephra mixed in with precipitation can also be acidic and cause acid rain and snowfall.
