Volcanic eruptions

Volcanic eruptions are part of the volcanic activity is known by the term \ "erupted \". Almost all volcanic activity berkaitandengan active seismic zone associated with the boundary lempeng.Pada because the plate boundary is a change of pressure and high boiling temperature so as to melt the surrounding material yangmerupakan incandescent fluid (magma). Magma will mengintrusi atautanah surrounding rocks through-cracks near the fracture surface of the earth.

Each volcano has its own characteristics jikaditinjau of vomit or type of product. Akantetapi any product type activities tetapmembawa volcanic eruption disaster for life. Dangers of volcanic eruptions memilikiresiko destructive and deadly.
Volcano Eruption hazard is divided into two by the time it happened, that is
Main Danger (Primary)1.Awan Heat, is a mixture of material between the gas eruption danbebatuan (all sizes) pushed down due to the density of the saturated tinggidan is rolling in dough bagaikangunung cloud turbulence along the slope. In addition to very high temperatures, antara300 - 700 º Celsius, lumpurnyapun very high speed,> 70km/jam (depending on slope).
2.Lontaran Materials (incandescent), occurs when the eruption (magmatic) takes place. Lontarannya much depends on the magnitude energiletusan, can reach hundreds of meters away. In addition to high temperature (> 200 º C), the size of the material was large with a diameter> 10 cmsehingga able to burn at once hurt, even deadly mahlukhidup. Also commonly referred to as \ "volcanic bombs \".
3.Hujan Abu thick, occurs when volcanic eruptions sedangberlangsung. Fine-sized material (ash and fine sand) yangditerbangkan wind and rain of ash fell as wind direction and the direction tergantungdari. Because the size is fine, this material will sangatberbahaya for respiratory, eye, groundwater contamination, pengrusakantumbuh-containing plants and chemical elements that are capable asamsehingga lead to corrosion of zinc and aircraft engines.
4.Lava, is magma that reaches the surface, its liquid (viscous fluids and high temperature, between 700-1200 º C. Because of the liquid, then the lava flows generally follow the slope and burn anything yangdilaluinya. When the lava has cooled, then his form into stones (batuanbeku ) and the area in its path will be a field stone.
5.Gas Poison, appeared not always preceded by the eruption of this gas apisebab can exit through the cavities ataupunrekahan-cracks are found in volcanic regions. Gas main emerge yangbiasanya is CO2, H2S, HCl, SO2, and CO. The kerapmenyebabkan death is CO2. Several mountain memilikikarakteristik poisonous gas eruption was Mount Tangkuban Fire Boat, Dieng Volcano, Mount Ciremai, and the Mountain of Fire Papandayan.
6.Tsunami, generally can occur in volcanic islands, where there saatletusan materials will provide the energy besaruntuk pushing seawater towards the coast resulting in gelombangtsunami. The larger the volume of material greater eruption yangterangkat waves ashore. For example, the case is the eruption of Mount Krakatautahun 1883.
Joined Danger (Secondary)Danger follow-up is the danger of volcanic eruptions that occurred setelahproses explosion took place. When a volcano erupts akanterjadi buildup of material in various sizes at the top and lerengbagian above. During the rainy season comes, in part tersebutakan material carried by rain water and mud down the dough is created lembahsebagai rocks flood, floods are called lahars.
Preparation In the face of the Volcano Eruption

    Recognizing the local area in determining a safe place to evacuate.
    Creating a disaster plan.
    Preparing for evacuation if necessary.
    Preparing for basic needs
    If a Volcano Eruption Occurs
    Avoid areas prone to disasters such as mountain slopes, valleys and lava flow area.
    In the open air, protect themselves from ash and pyroclastic eruptions. Prepare yourself for the possibility of subsequent disasters.
    Wear clothing that can protect the body such as: long sleeves, long pants, hats and more.
    Do not wear contact lenses.
    Wear a mask or cloth to cover the mouth and nose
    When the drop in the hot clouds try to cover her face with both hands.
    After Volcano Eruption Occurs
    Stay away from areas affected by ash fall
    Clear roofs of ash heap. Due to its weight, can damage or tear down the roof of the building.
    Avoid driving in areas affected by ash fall can cause engine damage

Hurricane winds

Hurricane winds are swirling winds with wind speeds of 120 km / h ataulebih that often occur in the tropics between the Tropic of Capricorn utaradan south, except in areas that are very close together dengankhatulistiwa.

Hurricanes are caused by pressure differences in suatusistem weather. Fastest winds that occur in the tropics iniumumnya swirling with hundreds of miles around daerahsistem extreme low pressure at about 20 Km / jam.Di Indonesia known as the wind storm.
Symptoms and Early WarningTropical cyclones can occur suddenly, but sebagianbesar storm formed through a process over several days jamatau which can be monitored by weather satellites. Monitoring dengansatelit can to find out the direction of hurricanes so it is quite waktuuntuk provide early warning. Nevertheless sistemcuaca changes are so complex that difficult to make predictions quickly danakurat.
Strategy for Disaster Reduction and Mitigation Efforts1. Creating a structure that meets the technical requirements to be able to withstand the wind force.2. The need for the application of rules of building standards that take into account wind loads, especially in hurricane-prone areas3. Placement of construction site facilities that are important in areas which are protected against hurricanes.4. Greening at the top of the wind direction to reduce wind forces.5. Making public buildings large enough to digunakansebagai temporary shelter for people and goods saatterjadi hurricane attack.6. Security / retrofitting of parts that easily in the wind that may endanger themselves or others around them.7. Preparedness in the face of hurricanes, knows how to rescue yourself.8. Security around the house items that are bound / built strong that the wind9. For the fishermen, so strong tether or tie his ships.

The bridge structure is still unstable Kukar Post-Crash
