Dust Explosion Hazards: Key Risks and

Dust Explosion Severity In order to assess dust explosion risks, both the severity of a possible explosion and the likelihood of ignition must be determined. To determine the dust explosion severity, the tester suspends a powder sample in a 20-liter spherical explosion chamber and a high-energy ignition source is introduced to cause an explosion.

Can nuclear explosions cause earthquakes?

A nuclear explosion can cause an earthquake and even an aftershock sequence. However, earthquakes induced by explosions have been much smaller than the explosion, and the aftershock sequence produces fewer and smaller aftershocks than a similar size earthquake.
