Disaster prevention
the lessening or limitation of the adverse impacts of hazards and related disasters.
Disaster mitigation
measures encompass engineering techniques and hazard-resilient construction as well as improved environmental policies and public awareness.
Mitigation

PHIVOLCS Earthquake Intensity Scale
Scarcely Perceptible:
Perceptible to people under favorable circumstances.
Delicately balanced objects are disturbed slightly.
Intensity Scale: I
Slightly Felt: Felt by few individuals at rest indoors.
Hanging objects swing slightly.
Still Water in containers oscillates noticeably.
Intensity Scale: II
Weak: Felt by many people indoors especially in upper floors of buildings. Vibration is felt like one passing of a light truck. Dizziness and nausea are experienced by some people. Hanging objects swing moderately. Still water in containers oscillates moderately
Intensity Scale: III
Moderately Strong: Hanging objects swing considerably.
Rumbling sound may sometimes be heard.
Intensity Scale: IV
Strong: Strong shaking and rocking felt throughout building. Hanging objects swing violently.
Dining utensils clatter and clink; some are broken.
Intensity Scale: V
Very Strong: Some people lose their balance. motorists feel like
driving in flat tires. Heavy objects or furniture move or may be shifted. Small church bells may ring.
Intensity Scale: VI
Destructive: Big church bells may ring. Old or poorly-built structures suffer considerably damage.
Some well-built structures are slightly damaged.
Intensity Scale: VII
Very Destructive: People find it difficult to stand even outdoors.
Many well-built buildings are considerably damaged. Concrete dikes and foundation of bridges are destroyed by ground settling or toppling. Railway tracks are bent or broken. Tombstones may be displaced, twisted or overturned.
Intensity Scale: VIII
Devastating: People are forcibly thrown to ground. Many cry and shake with fear. Most buildings are totally damaged. Bridges and elevated concrete structures are toppled or destroyed.
Intensity Scale: IX
Completely Devastating: Practically all man-made structures are destroyed. Massive landslides and liquefaction, large scale subsidence and uplifting of land forms and many ground fissures are observed.
Intensity Scale: X
The key to effective disaster prevention is?
planning
I. The key to effective disaster prevention is planning.
II. Prepare your homes, workplace or schools.
III. Familiarize yourself with the exit routes.
IV. Know where fire extinguishers, first aid kits, alarms and
communication facilities are located. Learn how to use
them beforehand.
V. Conduct and participate in regular earthquake drills
What to do BEFORE an earthquake
I. When you are INSIDE a structurally sound building or
home… STAY there! Do the “Duck, Cover and Hold”
II. If you’re OUTSIDE…
move to an open area!
What to do DURING an earthquake?
I. Be prepared for aftershocks. Once the shaking stops, take the fastest and safest
way out of the building.
II. DON’T use elevators, enter damaged buildings, use telephone unless necessary and PANIC
III. CHECK yourself and others for injuries, water and electrical lines for damages, for spills
of chemical, toxic and flammable materials, and control fires which may spread
IV. If you need to evacuate your residence,

Tephra
Volcanologists also refer to airborn fragments as?
pyroclasts
are turbulent mass of ejected fragmented volcanic materials (ash and rocks), mixed with hot gases(200oC to 700oC to as hot as 900oC) that flow downslope at very high speeds (>60kph).
Pyroclastic density current
are the more dilute, more mobile derivatives or pyroclastic flows.
Surges
rapid, gravity-driven mudflows or debris flows composed of water, volcanic ash, and rock fragments that originate from volcanoes, typically flowing down river valleys and causing significant damage and loss of life.

below the land surface is
limestone, carbonate rock, salt beds?
SINKHOLE
occur in response to a variety of both natural and manmade triggering events, such as earthquakes, heavy
rainfall, volcanic activity, or road and building construction.
Landslides
is generally used to describe the downward movement of earth materials driven by gravity.
LANDSLIDE
are abrupt movements of masses of geologic materials, such as rocks and boulders, that become detached from steep slopes or cliffs
FALL
involves forward rotation out of the slope of a mass of soil or rock a point below the center of gravity of displaced mass.

movement parallel to
planes of weakness and
occasionally parallel to
slope
SLIDE
may result from liquefaction or flow ( and extrusion) of the
softer underlying material.
