Drag marker to make changes take effect. There is currently a bug where 3psi does not work, so you will have to aproximate from the table.

Pressure Effects

Pressure Effects
1 PSI Glass shatters, Light injuries from fragments occur.
3 PSI Most residential structures collapse. Serious injuries are common, fatalities may occur.
5 PSI Most buildings collapse. Injuries are universal, fatalities are widespread.
10 PSI Reinforced concrete buildings are severely damaged or have collapsed. Most people are killed.
20 PSI Heavily built concrete buildings are severely damaged or have collapsed. Fatalities are nearly universal.
