Preventing and Tackling Natural Disasters

A.    Flood

Flooding is the overflow of river flow due to water exceeding the carrying capacity of the river, sehinngaa overflow and inundate the plains or lower areas in the vicinity. Flooding a problem if the flood impact damage or negative environmental impact manusai, among others: earthquake kit

  1. damage to infrastructure
  2. Tergangguanya human activity and economic activity
  3. Decreased quality of life

1.      Factors leading to flooding

  1. The influence of human activity: deforestation, settlement
  2. Natural conditions are fixed (static): geography, topology concave, streams
  3. Natural events that are dynamic: high rainfall, silting of the riverbed, the damming, land subsidence or subsidence

2.      Reduce the risk of flooding

  1. Physical activity (structure): construction of dams, dikes on the river banks, canals, construction of interconnection, polder development, and search the river
  2. Nonstruktur activity: management of flood plains, land conversion and water upstream, flood prevention
  3. The combination of structure and nonstruktur efforts

3.      Overcoming flood

  1. Flood preparation measures
  2. Actions during floods
  3. Post-flood effort

 

B.     Landslide

Landslides are a form of erosion that the transport or transfer of land occurred at some time in larger volumes. Common symptoms occur landslides:

  1. Cracks in the floor and walls of the building
  2. Ambles part of the flooring construction
  3. There are big mark on rock slopes
  4. Tilt trees
  5. The emergence of water rembasan
  6. River water level rose a few centimeters and river water becomes turbid suddenly
  7. The collapse of part of the land

 

1.      Factors leading to landslides:

  1. Slope angle increases for new construction
  2. Increased water content
  3. The loss of vegetation by fire
  4. Changing material slope
  5. Vibrations caused by earthquakes
  6. Extra load by rain

2.      Reduce the risk of landslides

  1. Survey and mapping of areas vulnerable
  2. Installation of signs
  3. Regulation of land use
  4. improvements in communications
  5. community education
  6. Monitoring and warning

3.      Overcome the Landslide

  1. Menetahui and avoid disaster-prone areas
  2. Understanding the actions in the event of post-disaster and landslides

 

C.    Tsunami

Tsunami is a term for the giant waves that move quickly and suddenly, caused by shifts in the seabed. The signs of impending tsunami:

  1. there is a strong vibration that can be felt around the beach
  2. after the tremor subsided, the sea water at the beach at low tide suddenly
  3. tsunami would come approximately 15 minutes after the earthquake
  4. The first wave came not too big, and the next is dangerous
  5. pay attention to the behavior of animals

 

1.      Reducing the Risk of Tsunami

  1. shoreline protection
  2. early warning system
  3. education and learning
  4. partnerships
  5. prone area mapping and evacuation
  6. post disaster preparation
  7. task force handling disasters

2.      Overcoming Tsunami

  1. determine areas prone to tsunami
  2. understand the actions of preparation, ahead, when they occur, and post-occur

3.      Rescue and Recovery

  1. Government assistance from the community and other parties
  2. priority in recovery

 

D.    Earthquakes

Earthquakes are genuine jolt of earth that comes in earth, propagate through the surface, and penetrate the earth. The most often used to measure the magnitude of a quake was magnitude.

Laingkungan forms of damage caused by the earthquake:

  1. Damage to the environment fasillitas
  2. Amblesnya ground
  3. Menghasilakn sea earthquake tsunami

 

1.      Reduce the risk of earthquakes

  1. Mapping the earthquake
  2. Monitoring earthquakes
  3. estimating earthquake
  4. Illumination of the earthquake

2.      Overcome earthquakes

Measures to cope:

  1. Know the earthquake-prone areas
  2. Observing animal behavior
  3. Understanding the actions before, during and after an earthquake
  4. Rescue and recovery

Actions to be taken:

  1. Evacuation and set up shelters for victims
  2. rescue
  3. Providing medical assistance
  4. Providing sanitation, water, food, and drinks
  5. Providing emergency education
  6. Conducting psychological recovery of the victims
  7. Repair and reconstruction of buildings, facilities, and other facilities.

E.     volcano erupts

The nature of volcanic eruptions is divided into two, namely effusive (erupt slowly) and explosive (meleeetus is explosive). Materials issued when the mountain erupted steamy ash, sand, rocks, gravel small, liquid-liquid silicate, solfatar, carbonic acid, and mofet. Signs of volcanic eruptions:

  1. An increase in temperature in the area surrounding the crater
  2. Simber water sources dry
  3. Frequent volcanic earthquake
  4. Often the sound of thunder
  5. The fall in the animals from the top of the mountain foot area

Environmental damage has occurred:

  1. Arise many victims
  2. Scattered volcanic dust that can endanger air
  3. Destruction of agricultural land
  4. The destruction of all material
  5. forest fire
  6. The drying up of water sources
  7. Damage to the environment

 

1.      Reduce the risk of volcanoes

  1. Harnessing volcano
  2. Not exploit volcano
  3. Understanding the danger of volcanic eruption

2.      Addressing catastrophic volcanic letuasan

  1. Prior to the eruption
  2. When there is a volcanic eruption
  3. When the eruption
  4. After a volcanic eruption
