Less than M2.0 (Micro): Microearthquakes, not felt. Recorded by seismographs.

M2.0 - 2.9 (Minor): Felt slightly by some people. No damage to buildings.

M3.0 - 3.9 (Slight): Often felt by people, but very rarely causes damage. Shaking of indoor objects can be noticeable.

M4.0 - 4.9 (Light): Noticeable shaking of indoor objects and rattling noises. Felt by most people in the affected area. Generally causes zero to minimal damage.

M5.0 - 5.9 (Moderate): Can cause damage of varying severity to poorly constructed buildings. Zero to slight damage to all other buildings. Felt by everyone.

M6.0 - 6.9 (Strong): Damage to a moderate number of well-built structures in populated areas.

M7.0 - 7.9 (Major): Causes damage to most buildings, some to partially or completely collapse or receive severe damage.

M8.0 and higher (Great): Major damage to buildings, and structures likely to be destroyed. Will cause moderate to heavy damage to sturdy or earthquake-resistant buildings.

The Richter scale, introduced in 1935 by Charles F. Richter in collaboration with Beno Gutenberg, is a logarithmic system designed to quantify the magnitude of earthquakes. It measures the amplitude of seismic waves to estimate the energy released during a quake. Each whole-number increase on the scale corresponds to a tenfold rise in wave amplitude and approximately 31.6 times more energy discharge. While the scale theoretically extends beyond 10, no recorded earthquake has ever reached that level.

Earthquake hazards encompass the physical effects and cascading consequences of seismic activity that threaten lives, infrastructure, and ecosystems.

Here's a clearer breakdown of the major types:

  • Ground Shaking: The most widespread hazard, responsible for collapsing buildings, bridges, and other structures due to intense vibrations.
  • Surface Rupture: Occurs when the Earth's crust breaks along a fault line, tearing through roads, pipelines, and foundations.
  • Landslides: Earthquakes can destabilize steep terrain, triggering landslides that engulf homes, roads, and entire communities.
  • Liquefaction: Saturated soil loses its strength and behaves like a liquid, causing buildings and roads to sink, tilt, or buckle.
  • Tsunamis: Underwater seismic events can displace massive volumes of water, unleashing powerful waves that devastate coastal areas.
  • Fires: Post-quake damage to gas lines and electrical systems can spark fires, compounding the destruction.

Here are essential earthquake safety tips to help you stay safe before a quake:

  • Secure Heavy Items: Anchor bookshelves, water heaters, televisions, and large appliances to walls to prevent tipping or falling.
  • Create a Safety Plan: Identify safe spots in each room—under sturdy tables, desks, or against interior walls away from windows and heavy objects.
  • Prepare an Emergency Kit: Stock up on essentials: water, non-perishable food, flashlight, extra batteries, first aid supplies, medications, and copies of important documents.
  • Practice Drills: Regularly rehearse the "Drop, Cover, and Hold On" technique with all household members so everyone knows what to do.
  • Know How to Shut Off Utilities: Learn how to safely turn off gas, water, and electricity to prevent fires or flooding after a quake.
