Cracks in the ground up to 1 m wide, avalanches, landslides. The rate of increase of the cracks can be up to 2 cm/s ġ0 (destructive) – collapse of many buildings In others – serious damage. Landslides, collapse and falling debris into the mountains.

Landslides and cracks up to a few centimeters on mountain slopes ĩ (devastating) – burglary of some buildings, falling walls, dividing walls and roofs. ħ (very strong) – significant damage to buildings Cracks in the plaster and breaking of individual pieces, thin cracks on the walls, cracks of chimneys Cracks in the foundations Ĩ (destructive) – destruction in buildings: large cracks on the walls, falling cornices and chimneys. An earthquake of magnitude 2 is subtle until the magnitude 7 is the lower limit of destructive earthquakes that cover large areas.ġ (undetectable) – only indicated by special devices Ģ (very low) – only felt by very sensitive pets and people in the upper floors of tall buildings ģ (low) – feels only in some buildings, like the vibration of a truck Ĥ (moderate) – the earthquake is felt by many people It is possible to balance open windows and doors ĥ (strong note) – shaking of hanging objects, noise in construction, window breakage, dust blowing Ħ (strong) – slight damage to construction of buildings, cracks in plaster, etc. Thus, the increase is a degree of magnitude of the 32-fold increase in the released seismic energy. The most popular scale of energy evaluation in earthquakes is the local scale of the Richter magnitude.
