B Phenomena of earthquakes related to the scale of Richter
and Mercalli
Considers environmental aspects related to climatic conditions (air temperature, humidity and pressure, rain, snow, ice, radiation, etc.); corrosive and erosive influences of physical and chemical agents in the air; as well as mechanical influences (vibrations, mechanical shocks, earthquakes). Particular conditions directly related to fire and explosion hazards and to ionizing radiation are not considered.
