Answers
a sudden violent shaking of the ground, typically causing great destruction, as a result of movements within the earth's crust or volcanic action.
the earthquake zoning map of India divides India into 4 seismic zones (Zone 2, 3, 4 and 5) unlike its previous version, which consisted of five or six zones for the country.
Earthquake environmental effects. Earthquake environmental effects are the effects caused by an earthquake , including surface faulting, tsunamis, soil liquefactions, ground resonance, landslides and ground failure, either directly linked to the earthquake source or provoked by the ground shaking.
Adoption of nonstructural measures. Businesses and homes should incorporate nonstructural mitigation measures to minimize injuries and property damage from natural disasters. Furniture and equipment, for example, can be easily secured to reduce injuries and damage from earthquakes.
