# Safest spots when an asteroid hits? [closed]

I am breaking this question and no longer making an effort in refining it with the exception of adding an associated link with the scenarios.

I always wondered if a devastating asteroid was predicted to impact the Earth where in the world would I have the highest chances of surviving the blast and short-term aftermath like seismic activity.

Which of these scenarios would have the best chances of survival?

Scenario 1. In the air of some type blimp or aircraft on the opposite side of the Earth? How is radiation dispersed by Earth's atmosphere?

Scenario 2. On or Underground in a cave? Can a shock wave be felt all the way around the Earth?

Scenario 3. In a submarine or capsule underwater? Does being under water provide any protection from a asteriod?

No point on Earth is truly safe without the known impact of the asteroid, but are there points on the Earth, even if you are on the other side, that you don't want to be like near fault lines?

• Regarding your scenario 2: the mantle is solid rock. Things don't "sink" in it, at least not in human time scales. Feb 28 '18 at 22:35
• I don't know if it's precisely Earth science but some safety tips for asteroid impacts wouldn't be a bad idea. A big one that heats up the Earth you might want a cellar (not everyone has access to a cellar, but it would help keep cool). #1 tip is don't watch it from a glass window, when the pressure wave hits the glass will shatter. You're mostly OK watching until it hits the ground but then get away from anything glass, don't stand by the window watching after the impact unless you want a face full of glass. Mar 3 '18 at 11:29
