I'm not sure if a "survival" PSA would be well received, but a "preparedness" PSA at the beginning of hurricane season focused on Hurricane preparedness and survival might be better. Use that medium to start getting people in a survival mindset thinking "be prepared" and get them moving in the right direction, stockpiling critical items and understanding that help may take time.

An Earthquake Preparedness PSA might be useful in earthquake prone areas like California and along the Madrid fault in the Midwest. There might already be one, but I don't recall seeing it.

Some will take the lessons further; for some watching cartoons or video games would be an upper limit.
