desastres naturals
Disasters are intense alterations of persons, property, services and the environment, an event caused by natural or manmade, that exceed the response capacity of the affected community.
CLASSIFICATION .-
Using the criterion of the Organization of the United Nations (UN), disasters are disasters are classified as follows:
1) Environmental and
2) Technological Disasters.
NATURAL DISASTERS .-
These are disasters caused by the force of nature. Among these are:
1. DISASTER GENERATED BY DYNAMIC PROCESSES IN THE INTERIOR OF THE EARTH .- Coma
a. Earthquakes .- The movements of the earth's crust that generate intense deformation in the rocks inside the Earth, building up energy is suddenly released in waves that shake the earth's surface.
b. Tsunamis .- Movimientode Earth's crust in the ocean floor, forming and propagating waves of great height.
c. Volcanic Eruptions .- It is the passage of material (magma), ash and gases into the earth to the surface.
2. DISASTER GENERATED BY DYNAMIC PROCESSES IN THE SURFACE OF THE LAND .- Como:
a. .- Landslides that occur as a result of sudden or gradual changes in the composition, structure, hydrology and vegetation of an area in decline or incline:
b. Landslides .- It is the fall of a strip of land that loses its stability or destruction of a structure built by man.
c. Landslides .- Mass of snow moves downhill.
d. Floods .- Flows of large volumes of mud, water, ice, friction, caused by the rupture of a pond or a snow slide.
e. Huaycos .- Landslides of mud and rocks due to rainfall, is presented as a stroke of muddy water slides at high speed on dry ravines and low flow dragging rocks and logs.
3. DISASTER GENERATED BY O WATER weather phenomenon .- Como:
a. Floods .- slow or violent invasion of river water, ponds or lakes, river due to heavy rainfall or dam breaks, causing considerable damage. They may occur in slow or plains and violent or sudden high gradient mountain regions.
b. Drought .- deficiency of moisture in the atmosphere by rainfall irregular or inadequate, inappropriate use of groundwater, water tanks and irrigation systems.
c. Frost .- Produced by low temperatures, causing damage to plants and animals.
d. Storms .- atmospheric phenomena produced by electrical discharges in the atmosphere.
e. .- Hail Precipitation in the form of water droplets solid ice.
f. Tornadoes .- Hurricane winds that occur in a rotating at high speeds.
g. Hurricane winds are exceeding .- plus 24 km / h as a result of the airecaliente intracción, moist Pacific Ocean is cold air.
4. ORIGIN OF BIOLOGICAL DISASTERS .- Como:
a. Pests .- The calamities produced in crops by certain animals.
b. .- The widespread outbreaks of infectious diseases to a large number of people in a particular place.
5. TECHNOLOGICAL DISASTERS .- Como:
a. Fire.
b. Explosions.
c. Chemical Spills.
d. Environmental Pollution.
e. Wars.
f. Subversion.
g. Terrorism.
DISASTER IN THE TOWN COMMON
Among the natural phenomena causing disasters are more common in Arequipa, we have:
1. Huayco .- These phenomena come to be the landslide of muddy water bodies, taking the beds of streams.
The landslides announce their presence with loud noise, and have a destruction that could disrupt poderde towns, fields, roads, etc..
MEASURES .-
We have the following:
a. Do not build their homes near the gullies.
b. Evacuate to higher ground.
c. Rational utilization of water and food reserves.
d. Assist victims.
e. To guard against repetition of the phenomenon.
2. SEISMIC MOVEMENTS .- The vibrational motions of the earth's crust and are basically two: the tremors and earthquakes.
Tremors .- The earthquakes of low intensity and short duration. The effects are also mild.
a. Earthquakes .- The strong earthquakes of intensity and long duration, landslides and mudslides caused by materials inside the earth or by volcanic activity effects. The effects are devastating.
Earthquakes are measured by their magnitude and intensity. Owing to its size most commonly used scale is the Richter scale.
Earthquakes generally have a magnitude between O and 9 degrees.
MEASURES .-
The most important are:
a. Before the quake, keep in mind where they are located the areas of security.
b. At the time of the emergency, we should act calmly. avoid creating panic in others.
c. Scroll and lead others to safety zones.
d. Stay away from dangerous places, poles, cables, old buildings, etc.
e. After the earthquake remain calm and observe the following conduct, avoid negative rumors, away from fallen wires. not to enter damaged buildings, help pick up debris, etc..
3. Slides and collapses .- The violent displacement of large masses of soil and rocks.
These destructive phenomena occur due to excessive moisture, as a result of heavy rains and the steep slope of the soil, which allow the occurrence of an event of this nature.
Landslides and floods often occur in interprovincial roads, so rough and uneven soil causing great damage in transport in general.
MEASURES .-
It should take the following measures:
a. Learn about the presence of rainfall in the months from December to April and mainly in the region of the Sierra.
b. Do not build housing and public works in hazardous locations.
c. Upon collapsing or sliding rapidly flee to higher ground and not return for any reason.
d. Stay alert and comply with the authorities.
4. FLOOD .- The slow or violent invasions of the waters of a river, lake, pond, dipping land on the banks of water covering the surrounding areas.
Floods are caused by growth of water flow in a river, lake or lagoon, as a result of rainfall increases. These natural phenomena are causing the destruction of farmland, villages and sometimes leaves a wake that causes infectious diseases and epidemics.
MEASURES .-
We must take the following:
a. Watch for information in rainy weather.
b. As floods are generally predictable, it must coordinate actions to act appropriately.
c. Actively participate in all that is required, coordinating with Civil Defense authorities.
d. After the flood, properly sanitize the entire area to prevent diseases and epidemics.
