Displaced. ≈300,000. On 4 August 2020, a large amount of ammonium nitrate stored at the Port of Beirut in the capital city of Lebanon exploded, causing at least 218 deaths, 7,000 injuries, and US$ 15 billion in property damage, as well as leaving an estimated 300,000 people homeless. A cargo of 2,750 tonnes of the substance (equivalent to ...
Exploding head syndrome ( EHS) is an abnormal sensory perception during sleep in which a person experiences auditory hallucinations that are loud and of short duration when falling asleep or waking up. [ 2][ 4] The noise may be frightening, typically occurs only occasionally, and is not a serious health concern. [ 2]
Blast injury. A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [ 1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition of a large amount of energy in a small, very localised volume. The flow field can be approximated as a lead shock wave, followed by a similar subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding supersonically outward ...

Bark, sound of a dog. Bleat, sound of a sheep. Buzz, sound of bees or insects flying. Chirp, bird call. Chirp, sound made by rubbing together feet or other body parts, e.g. by a cricket or a cicada. Gobble, a turkey call. Growl, low, guttural vocalization produced by predatory animals. Hiss, sound made by a snake.
An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when ...
Much of the destruction caused by a nuclear explosion is from blast effects. Most buildings, except reinforced or blast-resistant structures, will suffer moderate damage when subjected to overpressures of only 35.5 kilopascals (kPa) (5.15 pounds-force per square inch or 0.35 atm).
