Predicting Natural Disaster

Natural disaster is something that happens suddenly nad causes much suffering or loss to many people.

Landslide, Floods, Wildfires, thunderstorms, and etc. Natural disasters has a very bad effect or result to our community and to its people. It’s a sudden calamitous event bringing high damage, loss or destruction. Natural disaster can’t be predicted nor prevented that’s why you have to be prepared that this disaster may suddenly occur anytime. Being unprepared for this events to happen may result high damage and loss to many people. Government made a safety tips to the people in preparation for this sudden events to lessen the damage and loss to people in our community. This program is very important to all peolple because in this program you will know what to do when sudden disaster happen. 

Predicting Natural Disaster

The prediction of natural disasters has been so hard for the scientist. Many organization are experimenting and inventing advance technolgy on predicting natural disaster to make the people aware for them to be safe.

We all know that natural disasters can cause loss of life and damage property and there is now way we could predict it that’s why we have to prepare for this events. 6 years ago a typhoon named “Yolanda” hit the eastern and central part of Philippines and killed a lot of filipinos. Typhoon Yolanda was one of the strongest typhoon ever recorded. On going imporovement in data quality my lead to increased disaster prediction accuracy.

Disaster issued have been investigated by both natural and social scientist in interdisciplinary way. Most natural disaster data are fraught with problems, in terms of both the methodologies of disaster analysis and the collection of data. Information for a similar calamity are regularly gathered by organizations with various or notwithstanding contending destinations. There are no agreed-on criteria for defining specific disaster data measures, nor is there a specified time period for any given disaster.

Landslide

Landslide is the constant and gradual processes of erosion and weathering create the material that falls in soe landslide. There are many reason why material becomes unstable and slide begins. A volcanic eruption or an earthquake can start a landslide of rock and soil. The wide range of triggers that can begin a slide that they are often difficult to predict. Earthquakes are another major cause of disastrous landslides. During an earthquake, rock moves deep underground shifting and lossening the rocks and soil above. In Colobia, an earthquake on June 6, 1994 , set off landslides in the steep valleys around the Paez River valley to form a massive debris flow that partially destroyed several towns and killed more than 1000 people.Landslide are a type of “mass wasting ,” which denotes any down-slope movement of soil and rock under the direct influence of gravity. 

The expression 'landslide' envelops five methods of incline development: falls, topples, slides, spreads, and streams. These are additionally subdivided by the sort of geologic material (bedrock, flotsam and jetsam, or earth).Debris flows and rocks falls are example of common landslide types. Almost every landslide has multiple causes. Slope movement occurs when forces acting down-slope (mainly due to gravity) exceed the strength of the earth materials that compose the slope. Causes include factors that increase the effects of down-slope forces and factors that contribute to low or reduced strength. Landslides can be started in slants as of now very nearly development by precipitation, snowmelt, changes in water level, stream disintegration, changes in ground water, quakes, volcanic movement, aggravation by human exercises, or any blend of these components.

Wildfires 

Wildfires is a fire that rages out of control through forest or brush. It may destroy everything in its path and can produce terrifying whirling storms of fire. Wildfires usually bein in unpopulated areas, but they can approach human settlements and urban areas, where they become very dangerous to people. Every year in the United States, some 135,000 wildfires burns across nearly 4 million acres(1.6 million hectares). Wildfires typically take place as the result of certain condition particularly drought, which causes vegetation to dry out. Such fires are common in the Austrialian bush; In California and Southeast Asia, China, Russia, and Southern Europe; and the grasslands ad forest of Africa and south America. There are three conditions that should be available all together for a rapidly spreading fire to consume, which firemen allude to as the flame triangle: fuel, oxygen, and a warmth source. Fuel is any combustible material encompassing a flame, including trees, grasses, brush, even homes. 

Dry Climate

The more prominent a territory's fuel load, the more extraordinary the flame. Air supplies the oxygen a flame needs to consume. Warmth sources help sparkle the rapidly spreading fire and convey fuel to temperatures sufficiently hot to light. Lightning, consuming pit fires or cigarettes, hot breezes, and even the sun would all be able to give adequate warmth to start a fierce blaze. Albeit four out of five fierce blazes are begun by individuals, nature is typically glad to help fan the flares. Dry climate and dry spell convert green vegetation into completely dry, combustible fuel; solid breezes spread flame rapidly over land; and warm temperatures support ignition. At the point when these elements meet up the entirety of that is required is a flash—through lightning, illegal conflagration, a brought down electrical cable, or a consuming pit fire or cigarette—to touch off a burst that could keep going for quite a long time and devour a huge number of sections of land.

Prevent Flooding 

Flood is a waterway that makes regularly dry progress. Most floods occur when rivers overflow and the city don’t have a proper drainage system. Engineers use several different methods to try to prevent flooding alongside rivers and on coast. Dams provide a useful ool for controlling floods. Excess water is released down the spill way of the Dam to prevent flooding after heavy rain. People struggle to hang on to a rope stretched across a flooded street in Mumbai, India, on July 27, 2005, on day after the heaviest rainfall ever recorded in India on a single day. A flood happens when water floods or immerses land that is typically dry. This can occur in a huge number of ways. Most normal is when waterways or streams flood their banks. Exorbitant downpour, a cracked dam or levee, quick ice dissolving in the mountains, or even a lamentably put beaver dam can overpower a stream and send it spreading over the neighboring area, called a floodplain. Seaside flooding happens when a vast tempest or tidal wave makes the ocean flood inland. Most floods take hours or even days to create, giving inhabitants plentiful time to plan or clear. Others create rapidly and with small cautioning.

Glimmer Floods

These glimmer floods can be very risky, quickly transforming a jabbering stream into a roaring surge of water and clearing everything in its way downstream. Fiasco specialists characterize floods as per their probability of happening in a given timeframe. A hundred-year flood, for instance, is an incredibly extensive, ruinous occasion that would hypothetically be relied upon to happen just once consistently. In any case, this is a hypothetical number. As a general rule, this grouping implies there is a one-percent chance that such a flood could happen in anygiven year. Over ongoing decades, perhaps because of worldwide environmental change, hundred-year floods have been happening worldwide with startling consistency.

Dazzling Flash of Lightning Streaks

Thunderstorms are dazzling flash of lightning streaks across a stormy sky, followed by a deafening clap of thunder. This awesome display of nature’s power could be destructive despite of its amusing view. Thunderstorms can cause massive destruction. Thunderstorms are powered by energy from the sun. Tororo, in Uganda, East Africa, holds the record for the best number of rainstorms every year. In the united States, thunderstorms occur most comonly in the Southeast, particularly in Florida. Rainstorms are known to happen in pretty much every area of the world, however they are uncommon in polar locales and inconsistent at scopes higher than 50° N and 50° S. The calm and tropical areas of the world, thusly, are the most inclined to tempests. In the United Staes the areas of maximum thunderstorm activity are the Florida peninsula (more than 90 thunderstorm days per year), the Gulf Coast (70–80 days per year), and the mountains of New Mexico (50– 60 days for each year).Central Europe and Asia average 20 to 60 rainstorm days out of every year. It has been assessed that at any one minute there are around 1,800 tempests in advancement all through the world.
