The new volcanoes build so rapidly and explode so forcefully that they boil the sea above them into a hurricane of acid rain, which immediately impacts the Southern Air Temple and Kyoshi Island. Airbenders must take to the sky to avoid being killed by the quake, and some don’t make it out. The new plate boundary alters all marine life in the area, disrupting commercial fishing and local ecosystems.ĥ-30 minutes later: On the other edge of the Kyoshi Plate, the crust is catastrophically subducting beneath an island in Air Nomad territory, triggering an enormous earthquake exceeding 9.5 on the moment magnitude scale, as well as both old and new volcanoes. The eruption is much like a geyser, and marine life is launched into the atmosphere to fall several miles away. The lava boils the surrounding ocean water, shooting steam high into the atmosphere, where it condenses into clouds and rain. The local beaches become too dangerous to use, and the entire shoreline is transformed into a cliff face. Immediate effects: Kyoshi creates a new divergent plate boundary, flooding the ocean floor with lavas and introducing new oceanic crust without the benefit of a continental shelf. This has drastic consequences on the world. Setting: Avatar Kyoshi splits her peninsula in half and pushes her chunk of land out to sea, transforming it into an island.
