Earthquake Hazards and Safety Measures

Earthquake Hazards

• Effects of earthquakes include flooding, coastal erosion, drowning, and damage to properties
• Earthquakes can trigger tsunamis, as seen in the 1976 Moro Gulf earthquake

Preparing for an Earthquake

• Know the earthquake hazards in your area
• Strap or bolt heavy furniture/cabinets to the wall
• Check the stability of hanging objects like ceiling fans and chandeliers
• Store breakable items, harmful chemicals, and flammable materials in lowermost secured shelves
• Familiarize yourself with exit routes
• Know the location of fire extinguishers, first aid kits, alarms, and communication facilities

Understanding Earthquakes

• Earthquakes are a feeble shaking to violent trembling of the ground produced by the sudden displacement of rocks or rock materials below the earth’s surface
• There are two types of earthquakes: volcanic and tectonic
• In the Philippines, there is an average of 30 to 40 earthquakes per day

Types of Earthquakes

• Volcanic earthquakes are induced by rising lava or magma beneath active volcanoes
• Tectonic earthquakes are generated by the sudden displacement along faults in the solid and rigid layer of the earth
• Active faults are faults that have moved within the last 10,000 years

During an Earthquake

• Don't use elevators
• Don't enter damaged buildings
• Avoid using phones unless necessary
• PANIC (check yourself and others for injuries, and water, gas, electrical lines, and other parts of your residence for damages)

Making a Building Earthquake-Proof

• Create a flexible foundation
• Use vibrational control devices
• Utilize pendulum power
• Use earthquake-resistant materials
• Reinforce the building's structure
