I am just guessing that asteroid avoidance isn’t on your hazard risk analysis?!?! Asteroid Day (June 30) is held on the anniversary of the 1908 Siberian Tunguska event, the largest asteroid impact on Earth in recent history. The Tunguska asteroid was only about 40 meters in size but the impact was 1000 times more powerful than the Hiroshima nuclear bomb.
Large asteroid strikes are low-probability, high-impact (and death) events–so high-death that by some estimates the probability of dying from an asteroid strike is on the same order as dying in an airplane crash.
It is estimated that the Tunguska explosion knocked down some 80 million trees over an area of 2,150 square kilometres (830 sq mi), and that the shock wave from the blast would have measured 5.0 on the Richter scale. An explosion of this magnitude would be capable of destroying a large metropolitian area but due to the remoteness of the location, no fatalities were documented. This event has helped to spark discussion of how to avoid an asteroid impact!
Something to think about as you start your continuity planning/emergency management day!
