Greenland 2: Migration

Five years after the Clarke interstellar comet destroyed most of Earth, the planet remains in periodic violent tectonic and volcanic chaos, as sudden electromagnetic storms can unpredictably form, along with lingering radioactive fallout. The Garrity family survived since the initial chaos, with Allison now a leader, John a scout and engineer maintaining the bunker facility, and their now 15-year-old son Nathan a student who wants to become a scout. Rising earthquakes collapse the bunker and force an emergency evacuation. Most survivors are killed by a subsequent tsunami and the facility is lost.
