Study Notes

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
