It is used as a synonym for an apocalyptic event and is a common feature of science-fiction literature, films, and other media. They can be all-encompassing leading to the extinction of all life, including humans, on Earth.
Other scenarios can be more "minor" whereby "the cultural, technological, environmental or social world is so greatly altered it could be considered as a different world." - Wikipedia.

Which apocalyptic events are governments planning for, if anything?
Here are 5 examples of apocalyptic events that governments around the world are at least attempting to plan for.
1. Planning for the coming zombie apocalypse
Believe it or not but some governments have actually produced disaster plans in case of an event akin to a zombie apocalypse. The United States' Centers for Disease Control posted tips on how to survive one should it ever occur.
These tips are obviously made partly in jest but have serious real-life applications in case of more realistic events such as large hurricanes. It contains information on what should be included in your emergency provisions.
"If you prepare for the zombie apocalypse, you'll be prepared for all hazards," says CDC spokesman Dave Daigle.
This includes things like clean drinking water, food, medication, tools, and other supplies. sanitation and hygiene products and first aid supplies to name but a few.
It's actually a very interesting read and I would recommend that you give it a quick once over. While it is humorously written to address a zombie apocalypse, it is applicable to many other disaster events in the real-world.
2. Some nations are planning for the worst-case scenarios of global warming
Whatever your views on this issue, many governments around the world have been planning for the worst-case scenario. Island governments are particularly concerned about the possibility of rising sea levels for obvious reasons.
One example is the island nation of Kiribati in the middle of the Pacific Ocean. The island is barely above sea level as it is, and any major rises would completely drown the island.
