Less than 2.0—Micro— Micro earthquakes, not felt, or felt rarely by sensitive people
2.0–2.9—Minor— Felt slightly by some people.
3.0–3.9—often felt by people, but very rarely causes damage.
4.0–4.9—Light —Noticeable shaking of indoor objects and rattling noises. Moderate to significant damage very unlikely.
5.0–5.9— Moderate— Can cause damage of varying severity to poorly constructed buildings.
6.0–6.9 —Strong—Damage to a moderate number of well built structures in populated areas.
7.0–7.9 —Major— Causes damage to most buildings, some to partially or completely collapse or receive severe damage. Felt across great distances with major damage mostly limited to 250 km from epicenter.
8.0–8.9— Great—Major damage to buildings, structures likely to be destroyed. Damaging in large areas up to 500 kilometers from epicenter.
9.0 and greater— Near or at total destruction -Heavy damage and shaking extends to distant locations over a thousand kilometers from epicenter. Permanent changes in ground topography.
