Bhavna Sharma EST 330 TA Notes Week 2 Predictions of Natural Disasters Most disasters are unpredicted 99% of the time With earthquakes‚ history will tell us that one is possible‚ but it can’t say when one will occur‚ or at what time‚ or at what magnitude With tropical cyclones we know of the existence of a storm about 7 or 8 days in advance‚ but there is still great uncertainty about exact location of landfall until 24 hours before. Useful tools: satellites- ability to see where tropical

Derron Brown Period 3 Hurricanes and Earthquakes Have you ever noticed how many deaths have occurred due to natural disasters? Well if you don’t know what a natural disaster is‚ it is a natural hazard to the environment (floods‚ tornados‚ hurricanes‚ volcanoes‚ earthquakes‚ tsunamis). All of these natural disasters can cause severe damage to the environment and many deaths. In this essay I am only going to talk about earthquakes and hurricanes. An earthquake occurs when stored energy underneath

Introduction People tremble when they hear the word; destruction‚ mayhem‚ and tragedy: all words that come to mind when “earthquake” is heard. They occur without warning and cause millions of dollars in destruction and numerous deaths. For these reasons and more‚ earthquakes are one of the most unpredictable and devastating occurrences Mother Nature dishes out. Earthquakes usually occur without warning. There is a sudden slip in the earth’s crust‚ which makes the earth shake causing mass destruction

Of all the naturally occurring events on Earth‚ earthquakes are among the most devastating and bring a lot of truth to the statement‚ “Just because something is natural does not mean it is not dangerous.” Earthquakes are one of the most natural things I can think of that can cause massive damage and loss of human live in many instances‚ and the effects are sometimes long term. “Nothing happens without a force. Many geophysicists accept the theory that continents move as a result of the forces

Million Death Quake Review When Haiti was struck by an earthquake in 2010 the impacts were disastrous. With an official estimate of 316‚000 deaths‚ it is the second most destructive earthquake in recorded human history. Over 97‚000 houses were destroyed and more than 188‚000 damaged. However‚ could this Earthquake have been predicted and some‚ if not all‚ of the 316‚000 deaths prevented? Are we able to predict‚ or even prevent‚ the next large earthquake that is bound to rock our planet to the core? These

When we hear the word earthquake we get goose bumps because the word reminds fear in our minds does it not? Yes‚ it does‚ we think that an earthquake can kill us any moment destroying our homes into dust. Science tells that; Earthquake is the shaking of the earth’s surface caused by rapid movement of the earth’s rocky outer layer. Earthquakes occur when energy stored within the earth suddenly releases‚ the size varies from small hardly noticeable shaking‚ to large shocks which can be felt from miles

the 1994 Northridge earthquake occurred on January 17‚ 1994. The earthquake was centered in Reseda‚ a neighborhood in the north-central San Fernando Valley region of Los Angeles‚ California. “It was a 6.7 magnitude earthquake that lasted 10 – 20 seconds. In addition‚ two 6.0 magnitude aftershocks occurred‚ the first about one minute after the initial event and the second approximately 11 hours later‚ the strongest of several thousand aftershocks in all.” (USGS‚ 2012) Earthquakes are usually caused

Soil Liquefaction Dangers During Earthquakes An earthquake brings a number of hazards: • Ground shaking and shifting can cause major damage‚ tearing apart houses‚ buildings‚ and roads. • Flooding that arises from broken water dams or river levees is another hazard. • Tsunamis‚ triggered by an undersea earthquake as well as seiches – waves coming from lakes shaken by a temblor – can submerge whole communities‚ sweep away edifices‚ topple trees and drown people. • Fire is another seismic hazard

We can therefore assume that term a lithospheric hazard refers to those that are caused through geological processes that have threats to human life and the environment they live in. These types of hazards include things such as Volcanoes and Earthquakes‚ namely because their source of origins are directly linked to tectonic and earthly activity. With the occurrence of lithospheric hazards i.e. the hazard being turned into an event or disaster‚ there comes about effects in the short and long run
