Yes. The impact of a 2.5 mile wide asteroid would likely be the worst natural disaster in human history. The airblast would be devastating even hundreds of miles away. If it hit the ocean it would cause large tsunamis.
When talking about asteroidal impacts, it's worth noting that the diameter of an object is not an indication of potential impact. The density and more important is the velocity at which it impacts the Earth is. However, an asteroid with a diameter of 70 miles would not destroy the Earth. The Earth has been hit by much larger objects (Theia) and survived - yet only just. A 70 mile asteroid would make a large impact but it would not destroy the Earth. A 70 mile asteroid would however, with the right velocity and angle, in all probability, wipe all life off of the Earth and cause years of non regeneration. Simple life would eventually recolonise the planet, but it would take millions of years for complex animals to evolve. So much so, that a devastation on that scale would eliminate mankind from the Universe as we know it. The asteroid that wiped out the Dinosaurs and ended their reign was a mere 10 miles in diameter and produced 2 million times more energy that our most powerful atomic bomb. So the 70 mile asteroid would not destroy the Earth but it would certainly destroy everything on it.
An asteroid from space, like the one that killed the dinosaurs, which was a mile in width.
A cyclone. Cyclones cover areas hundred of miles wide. Tornadoes more than a mile wide are rare.
The asteroid belt lies in between the orbit of Mars and Jupiter. Over 40,000 asteroids with at least a half mile diameter are found in the asteroid belt.Asteroids.
It would be devastating. A shockwave would blow down everything in about a several hundred mile radius from the impact and a small firestorm would cover a large portion of the earth. Chunks of the asteroid would impact thousands of miles away causing large forest fires. A nuclear winter would occur from all the dust and debris kicked up from the blast and extinguish all plant life. Without plants, herbivores die, and without herbivores, most carnivores would die. The food chain would collapse entirely and there would be worldwide riots as millions die every day.

The old saying "a miss is as good as a mile", although if an asteroid were to pass within about 300 miles of the Earth, it would definitely be "too close for comfort"! A "safe" distance might be anything greater than about 25,000 miles, which would prevent it from colliding with our geosynchronous satellites as well.
No. (At least not this September)

Because if it were not, it would not be a mile!
The worst degree of damage that a tornado can cause is EF5 damage. In such cases well-built houses are wipec clean off their foundations and blown away. Even larger structures such as churches and small apartment buildings may be swept away. Steel reinforced structures may be completely destroyed. Fortunately, such damage only occurs along a realtively small portion of a tornado's track, which the exception of one tornado which carved an EF5 damage swath half a mile wide.
Well i did some rough estimates...prob be like 56 milesA blast radius is equal to the square root of the megatonage. A 1 megaton bomb has a blast radius of severe damage of about 4 miles. Therefore a 200 megaton bomb (14 being about the square root) would have about a 56 mile radius. Though direct exposure to the explosion at that distance could probably still cause severe burns and it would probably cause damage as much as 200 miles out.
