It's been only a few years since the sky rained fire and stone for 53 days. Much of Earth has suffered total devastation, but some places have managed to survive, barely.
The North American continent still exists, but most of it is barely livable. In the west, what still stands of the Rockies is the new west coast. In the east, the remaining Appalachia mountains have similar positioning. The old west coast is gone entirely. Very little of the old east coast remains. Mexico and the interior are still scorched and pitted from the many impacts they each suffered. Yellowstone still sends pillars of noxious fumes and ash skyward every day. What used to be Florida is nothing but a collection of sand bars and swamp.
A few of the British Isles made it through, but suffered massive damage. They were not only hit by falling, burning stone, but from record breaking tidal waves caused by Northern Atlantic impacts. Many of the islands, including a large portion of the larger island nations, were either burned or wiped clean during the onslaught.
Great Britain was literally swamped by the largest of the tidal waves. London suffered multiple hits, then was cruelly washed from the face of the land. Only a few shattered remains mark the location of this once grand city.
Ireland took so many hits it's central mass was obliterated. All that remains is a badly scorched ring of land surrounding a now inland, salt water sea with a few scattered bits of land within it's borders. At it's widest point, the surrounding ring of ground is believed to be just under ten miles wide.
Europe and Asia took so much damage they're unrecognizable. Even to the little life remaining there, of which none is human. Where Paris once stood in all her grandeur, there is nothing left but a still burning crater of molten rock. The entire Eurasian continent and the middle east are a toxic wasteland where little survives. Even with protective gear, they are places no human will walk for many generations.
South America and Africa were split open and the planet's molten core pored out and engulfed their lands in fire and ash. Little of them remain that is not shrouded in constantly renewing pyroclastic flows born from never-ending volcanic eruptions.
Australia and the nearby island nations of the western Pacific avoided a large portion of the impacts. They thought they were lucky, until a massive rock slammed into the sea bed in the central Pacific and sent a tsunami the likes of which had never been seen before to wash over them. A few people in the higher elevations survived, but the arrival of nuclear winter made them wonder if they had truly been the lucky ones, or if the dead were the ones who were better off.
The North Pole is known to be gone, the first to suffer massive impacts, but Antarctic's fate is still a mystery. There are rumors and stories everywhere, but no one can say for certain. Residue and radiation have plunged the survivors back into the dark ages. Man-made electricity is a thing of the past, and so are many of the advancements to be born from it's creation, plus something brought by the meteors dampens humanity's efforts to recreate it.
