Earth is hit every day by a small (<16') meteor that disintegrates before reaching the surface. The threat of a potentially hazardous Asteroid hitting the earth is real enough that several governments were concerned enough to take action.
The International Asteroid Warning Network was formed in 2013 at the request of the United Nations, to monitor "Near Earth Objects." Also, NASA is developing a craft called the Asteroid Redirect Mission and a robot to be sent to a near-Earth Asteroid.
Granted the likelihood of this occurring in our life time is low (< 1 in 10,000), but the consequences if it does are catastrophic. A small asteroid exploded in the in Siberia in 1908 and 20 years later the area was still devastated. At this point, some are saying, yea, but that was long ago, but a strike this size occurs about every 10 to 20 years, usually in the ocean or an unpopulated area. The power of this is about 1,000 times more powerful than the nuclear bombs dropped on Japan in 1945.
On February 15, 2013, an undetected asteroid 17 meters in diameter exploded 17 miles above Chelyabinsk, Russia. The energy from the air blast of the explosion measured the equivalent to 470 kilotons of TNT. The falling meteors from the explosion damaged buildings, shattered windows and injured nearly one thousand people.

Asteroid devastation could even be worse than feared
For those who are convinced and would like to be prepare, here is some food for thought. Many of the preps for this Event are the same as for other events.
An Asteroid Impact with Earth (or limited nuclear exchange) would destroy everything for potentially hundreds of miles, sending up enough dust into the atmosphere to block the sun for years, causing drastically cooler conditions. Earth could literally enter a man-made Ice Age. The EMP from a nuclear exchange could destroy all electronics that are not shielded, but that is another disaster for another post. Also, a Nuclear Winter would likely be less severe than an Asteroid Impact Winter.
Such Preparations would fall in two categories:
1) Surviving a 3-10 year winter, tidal waves, fire storms and acid rain. Within 20 days, the global average temperature would drop from 58 degrees (F) Fahrenheit to 35 F, recovering about 10 degrees after a year or two. By this time, 1/3 or more of the northern hemisphere (all of Canada and Northern US) would be covered year-round by snow. The entire earth would experience freezing in the winter, and only the darkest red areas would not be frozen year-round.
2) surviving the "break out" after the sky clears, and the weather warms enough to begin life outside again. The risk of unusually high ultraviolet exposure exists as the skies clear after being scorched. Disease from the fatalities decaying is a serious risk.
1) Surviving a 3-10 year winter
It could happen without any warning with only a matter of days to react. So a high level of preparation and readiness is important. What should we prepare for?
- Living underground where the earths temperature is more constant may be required. If not, a well-insulated shelter with a large supply of firewood, diesel or propane would be required making an "Event" like this, one of the most difficult to be prepared for. Note that an underground shelter also protects from radiation as well as severe storms and cold. See: Concrete Bunkers
- A ten year supply of long shelf life foods, water & warm clothing. See the post:
Identifying nearby food warehouses, school cafeterias and other such places that feed large numbers might be a place to salvage food. Animals that survive will likely be underground, underwater or able to withstand cold and eat grasses under the snow or bark and twigs of trees like goats, rabbits & deer.
- Green House to maintain your seed supply over such a long time and provide a small amount of food.
- Security plans with a large supply of Ammo to protect what you have. Here a few links:
2) Surviving the beak out
Nothing would be worse than surviving the extended winter and then not being prepared to survive the new world. Here is what you might need and some of this could be salvaged from hardware and farm supply stores.
- Extensive Farming and Ranching supplies, including seeds, plants, livestock, feed, tillers, seeders, garden tools like shovels, hoes, and rakes. Chickens, dogs, goats, pigeons, and rabbits are good animals to have.
- Green House to grow foods year-round.
- Hand tools like saws, axes, drills, nails, water pumps & barrels.
- Farming and Ranching Skills
- Security is still important as it will be easy to let your guard down at this point and be caught unprepared.
- Reproductive age adults for human re-population.
- Substantial loss of land based animals; large bodies of water may be a key source of natural food supply.
- Snow melting will cause flooding, even in normally dry places.
- Decaying animals may result in high amounts of airborne disease.
At this point, common long-term survival preparations are needed in addition to those to handle cooler and more erratic weather and shorter growing seasons. There is a tremendous amount of detail regarding a long-term sustainable meal plan that is important. How much do I need to plant and how many animals do I need to raise. The Prepper Handbook by JR Ray on Amazon covers all of this in great detail so we will not duplicate it here.
