Lesson learned with the help of technology
Natural disasters happen unexpectedly all over the world that can cause injury, death, and finical devastation, however over time technology can play a role in the question "why" and "when". The Aldercrest-Banyon landslide was one disaster that put Kelso, Washington on the worst urban landslides in the United States history when it comes to cost. (FEMA, 2013)According to Centers for Disease Control and Prevention (2012) "Landslides occur when masses of rock, earth, or debris move down a slope" (CDC, 2012) When the stability of a slope on the side of a hill side is disturbed this can eventually cause a landslide. The issue with Aldercrest-Banyon landslide, a consistency of rain fall over 3.5 years (above average rainfall), small housing developments built on a hazard place, and road excavation that took place on the lower part of the slide.(Davila, 1999) With the FEMA preparedness plan today, this situation could have cost less in damage and created an environment more stable; that still is unstable.
Aldercrest- Banyon residents were experiencing changes of ground movement. Signs were detected in February 1998, underground Utilities were damaged or breaking, residents’ homes were developing cracks, and road ways were splitting. "The problem was that the site had been erroneously mapped as stable ground, when in fact, the homes had been erected on an ancient landslide that just needed a little extra rain to reactivate." (Burns, 2007) Geologist has become a part of the prevention of natural disasters to monitor ground activity such as earthquakes and landslides. According to USGS (2013) every state must have some landslide information provided to the public. Reports were taken mid-April 1998...

...round movement, damages to homes, roads, and city property. In this day in age Geologists have become the leader on prevention in natural disasters before they happen. The preparation and prevention guided by city and state government that can minimize cost according to USGS (2013) are:
• Avoid buildings, slopes, mountain edges, and drainage ways in the hazard zones
• Watch storm-water drainage patterns.
• Minimize home hazards
• Have Gas Company or professional assist flexible pipe fittings.
• Plant ground covers cover on slopes and build retaining walls.
• In mud flow areas, build channels or deflection walls to direct flow around buildings.
By being prepared and informed in situations such as a landslide, City and State government can report assistance from FEMA for values on homes and help recover damages that could not have been prevented from Mother Nature.
"While the Northwest has experienced some unusual weather conditions this year, the effects of these weather conditions were not all unpredictable. Many tragic failures in the Pacific Northwest (and in other parts of the country) can be traced to poor land-use planning decisions. Despite the availability of hazard mitigation information and qualified technical consultants, the information is often ignored and the consultants bypassed as development continues in the flood plains and on unstable hillsides. Often, unwise site selection and ill-conceived site development results in unnecessary exposure to severe natural hazards."
Canada is a great place to live. Winnipeg… is good enough. Winnipeg is known for its diverse population, festive multiculturalism, beautiful architecture, vast prairie land and The Jets. One thing Winnipeg is definitely not known for, being a geological hazards hot spot. These hazards are geological events that take place, which have an impact on civilization. Canada is impacted by a wide scope of events ranging from earthquakes to fires. However, Winnipeg is lucky to be conveniently located away from any seismic activity, any threat of coastal dangers, any mountain risks and lastly it is absent of even the slightest volcano. Therefore, what Winnipeg lacks in attraction it makes up for in safety. In spite of its perceived security this major Canadian city is unfortunately prone to some very serious dangers. It is home to very cold, lengthy winters, dreadful storms that lead to wet springs. Scientifically speaking “geohazards are any geological or hydrological process that poses a threat to people and/or their property” (Bilderback, 2013). Thus, the geological hazards that will be discussed in this paper are flooding, landslides, and severe weather including tornadoes and storms.
The federal government provides a protected status, Special Immigrant Juvenile Status (“SIJS”), to immigrant youth that cannot be reunited with one or both of their parents due to abuse, neglect, abandonment, or another similar basis under state law. In order for Tatiana to be eligible for SIJS, federal law requires that a “juvenile court” issue a special finings order, an order that states the necessary factual findings that are a perquisite to petition United States Citizenship and Immigration Services (“USCIS”) for SIJS.
In 1972, R.I.S.E, a terrorist group was found to be guilty for contaminating Chicago’s water supply. The alleged plot to poison water was led by Steve Pera and Allan Schwander. The then commissioner of the Chicago’s water and sewage commission regarded the attack as a scheme of harebrained people and could not have worked. Typhoid germs were introduced to the drinking water supply by two college students, Pera and Schwander. However, the commissioner said that any plan to contaminate water will fail because of the chlorine being continuously pumped to water supplies every day. With that, Typhoid bacteria won’t be able to survive the said procedure. Apart from Chlorine, the water filtration plants are guarded 24/7 so plans of any attack won’t be feasible. The two students were held in Cook County Jail and had a bond of $250,000 each. Pera and Schwander were 18 and 19 years old, respectively, during the said attack. According to investigations, RISE, the terrorist group formed by the two suspects, were created to create the basis of the newly formed master race. The bacterial culture was prepared by Pera in Mayfair City College’s laboratory where deadly microorganisms are abundant. In fact, Pera used to work as a volunteer in St. Lukes Hospital but was terminated because of his attempt to acquire unauthorized chemicals (The Ledger, 1972).

The 1994 Northridge earthquake was a disaster, as it “involved an entire community” (Edwards, 2013). The earthquake resulted in extensive damage to the infrastructure of the community and localized, long term, multidimensional negative effects to the surrounding communities (Edwards, 2013). While the earthquake had many characteristics of a catastrophe, it did not include “significant damage to the disaster response assets and deaths or injuries to emergency response personnel” (Edwards, 2013). The earthquake required assets from outside the community, such as Caltrans and the FHWA. Also, the damage and disruption was “confined to a sufficiently narrow geographic area” (Edwards, 2013).
Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...
To begin, the chapter talks about the occurrence of “unnatural hazards” within geographic locations who are most susceptible to natural disasters. Slum housing almost two thirds of the urban population are built on unstable hillsides and on deep gorges surrounding the seismically active Caracas (Davis, 2006). I think it is important to analyze the effects of weaker geographical locations because it does have great bearing on urban planning in developing countries. When countries lack the proper infustructure needed to prevent or deal with natural disasters, it creates a ripple effect of issue that disturbs the ecological system.
... mitigation strategies. Analysis of several landslides within the New Madrid Seismic Zone indicated that the landslides were stable, but failure is possible during an earthquake of the magnitude experienced in 1812.
Living in Bangladesh, we have seen quite disastrous mudslides from the past few years. Mudslide is also called a landslide or a land slip. It is a downward mass movement of earth or rock on unstable slopes, including many forms resulting from differences in rock structure, coherence of material involved, degree of slope, amount of included water, extent of natural or artificial undercutting at the base of the slope, relative rate of movement, and relative quantity of material involved. There are numerous facts that can cause a mudslide and there are also numerous effects that it can cause us.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
There are different types and causes of disasters; man-made, natural and a combination. Man-made disasters are caused by human error or human actions that cause harm to the environment, and people (Baack & Alfred, 2013). Natural disasters are caused by nature a hurricane for example; and a combination; NA-TECH (natural-technological) examples are earthquakes that cause structural damage such as a collapse of a bridge (Nies & McEwen, 2011). Communities must have effective emergency preparedness in place to reduce the causalities from a disaster.
The least violent type of natural disasters is the flood; it is one of the most frequent hazards. A flood can affect local areas or a very large area affecting entire river deltas. Not all foods are alike, some of them develop slowly over a period days and some of them occur in a matter of minutes. The floods that develop quickly are known as flash floods; flash floods have a dangerous wall of thunderous water that carries rocks, mud and other different debris. If you live in a low-lying area near water you more prone to flooding, the smallest streams, gullies, creeks, and streambeds can cause a flood. Floods are often not a common thought when you think of a natural disaster, but they can be fatal, destroy homes, businesses, and roads, happen when you least expect, and happen when you are not prepared (FEMA:Flood). An extreme example of this type of natural disaster is the flood in eastern Australia last month; the flood, which lasted for weeks, caused thirty dea...
Of the four phases of emergency management, mitigation, preparedness, response and recovery, perhaps the place that individuals can make the biggest difference in their own state of resiliency and survival of a disaster is in the preparedness phase. Being prepared before a disaster strikes makes sense yet many people fail to take even simple, precautionary steps to reduce the consequences of destruction and mayhem produced by natural events such as earthquakes, volcanos and tornados (see Paton et al, 2001, Mileti and Peek, 2002; Tierney, 1993, Tierney et al, 2001).
