The energy released from an earthquake can be up to 10,000 times more powerful than the first atomic bomb! This shows how dangerous an earthquake can become. Is a hurricane that dangerous? Earthquakes are far more dangerous than hurricanes because they can cause damage to man-made structures and major water related issues.
To begin, earthquakes are more dangerous than hurricanes because they can severely damage man-made structures. In "Earthquakes: effects" the San Francisco earthquake of 1906 reportedly "caused 90% of damage by fire," (paragraph 9). This examplifies that fires started by earthquakes can cause damage to man-made structures, such as large buildings and houses. This may also prove that earthquakes can create multiple other
elements that can negatively effect an entire city. Also found in the same article, it's mentioned that," a residential area in Alaska (Turnagain Heights) as well as areas in downtown Anchorage were destroyed by a shock induced landslide," (paragraph 4). This demonstrates that an earthquake can cause unexpected shock waves that can wipe out an entire neighborhood and town. The shock can distrupt the enviroment by causing the land to suddenly collapse, therefore creating a landslide. As shown above, earthquakes can cause damage to man-made structures. To continue, earthquakes are more dangerous than hurricanes because they can cause major water related issues. In "Earthquakes: effects" it states
Earthquakes are best described as a shaking or vibration of the ground caused by breaking of rock. Sometimes they are very strong and other times you would hardly notice them. This shaking occurs when stress that builds up in the crust is suddenly released as the crust breaks free and/or slides against the other pieces of crust. Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time. Should you try this experiment , you will feel the pressure build up as you apply more force until the stick snaps. When the stick snaps you will feel an instant of pain at your fingers as the stress reduces and energy waves move throughout the stick. When the earth's crust is placed under similar types of stress, binding as the stress builds, it will also snap and release the energy into the surrounding rocks, 'ooch'. Thinking about earthquakes will become more clear if you try another experiment.
Earthquakes are the most powerful and with the largest magnitude of 9 on the Richter scale. The Cascadia Subduction Zone is a bit more complicated than the other two types of earthquakes. The zone separates the Juan de Fuca plates and the North American plate, subduction earthquakes happen when one plate is pushing beneath each other.... ... middle of paper ...
A hurricane is easily the most powerful storm that mother-nature can throw at us. Every year people who live on the coasts fight hurricanes with no dismay. A hurricane is simply too strong. Their winds reach speeds of 75 mph. The winds around the eye wall can reach 130 to 150 mph. They are 200 to 300 miles in diameter. The number of casualties is endless, as well as the widespread destruction that takes millions of dollars to repair. Even if the hurricane doesn’t cause a lot of damage, the storm surge will. Storm surge is the great tidal waves that crash into our coasts and make huge floods that are caused by hurricanes.
What is the most devastating natural disaster known? Hurricanes are one of the most catastrophic and natural events to ever be experienced. They can be up to 600 miles across and have wind speed of 75 to 200 mph. Hurricane Sandy and Hurricane Katrina happened to be two of the most devastating hurricanes in history.
More earthquakes can also cause more geological damage as well as increased loss of life. According to Klemetti Erik, an author for wired.com and an assistant professor of Geosciences at Denison University, “there were at least 14 earthquakes triggered during or after Novarupta’s eruption of a magnitude of 6 or greater occurred, releasing 250 times more energy than the earthquakes at Pinatubo in 1991. This is thought to reflect the lack of pre-existing faults from previous calderas in the location where the new caldera formed at Katmai”(Klemetti 2012). Earthquakes triggered by volcanoes are not very uncommon, but due to the scale of Novarupta, the numerous earthquakes triggered were also at a proportionally large
Mother Nature cannot be controlled and as humans we are forced to deal with various natural disasters. We have earth quakes, hurricanes, volcanoes, tornadoes and many other types of events that are weather driven. Many natural disasters affect our everyday lives and individuals may be forced to safe areas to protect themselves from potential danger. Natural disasters can also place a financial burden on people in affected communities. Hurricanes are strong storms that have been hitting the United States for as long as history can remember. Many hurricanes have hit the southeastern part of the United States the past 100 years. Some of these hurricanes have left little effect of society while others have scarred into the history
What have they learned since the quake quite allot. The fault moved in a fashion that geologists of
Hurricanes are powerful and destructive storms that involve great rain and wind. The United States of America has dealt with many hurricanes that have cost a great amount of damage. However, there is one hurricane that happened in 2005 that stands out among the others, Hurricane Katrina. Hurricane Katrina was one of the worst hurricanes to hit the United States, a category 5 on the Saffir/Simpson Hurricane Scale. An estimated 1836 people died because of the hurricane and the floodings that happened after (Zimmermann 1). Katrina initially beg...
Hurricanes are one of the deadliest and most expensive natural disasters around. They are more common in areas of humid yet moist weather so they are very foreign to certain places. But to the places were hurricanes are the norm, the people take them extremely seriously because they kill people and ruin countless amounts of property. Hurricanes can attack and harm people in so many ways they can kill people, leave them homeless, it leaves children orphaned and disable them. On the west coast of the United States and other places hurricanes aren’t taken as seriously as other more common disasters, such as, earthquakes and volcanoes yet the hurricane can be a lot more damaging that both of those. Hurricanes are cyclones that develop over warm oceans and breed winds that blow yup to 74 miles per hour.
Hurricanes are powerful atmospheric vortices that are intermediate in size. Hurricanes are unique and powerful weather systems. The word “hurricane” comes from a Caribbean word meaning “big wind”. Views of hurricanes can be seen from a satellite positioned thousands of miles above the earth.
It was a beautiful day like any other with the clear blue sky and the
A Hurricane is a tropical storm with winds more than 74 miles per hour (mph). Hurricane wind damage is influenced by the duration and change of wind direction, amount of rainfall and how well land structures are build. Hurricanes are measure in five different categories and each category can produce different degree of damages. Category One Hurricane has sustained winds 74-95 mph. Category Two Hurricane has sustained winds of 96-110 mph with very strong winds that can produce widespread damage and extensive damage to power lines. Category Three Hurricane has sustained winds of 111-130 mph that will cause extensive damage with near total power loss that could last several days to weeks. Category Four Hurricane has sustained winds of 131-155 with extremely dangerous winds causing devastating damage. Finally, a category five hurricane has sustained winds greater than 155 mph. This is a catastrophic damage storm. Category five can have severe injury or death due to wind blown debris. A Category five hurricane can produce extensive power outages that will last for weeks to perhaps months. Therefor...
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).
Hurricane is a natural disaster with far reaching consequences. It takes away the lives of millions of people and causes damage to almost all of human creation. It can cause extensive damage to coastlines and several hundred miles inland due to heavy rainfall. Floods and flying debris often plays havoc in the lives of people living along coastal areas. Slow moving hurricanes produce heavy rains in mountainous regions. Landfall and mud-slides can occur due to excessive rain. Chances of flash floods also brighten due to heavy rainfall. Below are some interesting facts about hurricanes.
Hurricanes occur all over the world, at different times, but commonly through June first and late November. However in late August 2005 a catastrophic hurricane struck. This was Hurricane Katrina. With winds traveling over one hundred miles per hour making it a category five on the Saffir- Simpson Hurricane Scale it was said to have cause billions of dollars’ worth of damage. Hurricane Katrina flooded nearly forty thousand homes, and killed at least two thousand people (“Hurricane”). An average category five hurricane has enough energy to power street lamps for more than twenty seven thousand hours (Williams 58). Knowing about Hurricane Katrina, and the devastation of the city in New Orleans would be beneficial. Also, general information on hurricanes can help civilians and people of higher authority better understand and prepare for damage that could once hit their town and community. Because experts know the general information on these storms they can help explain to the public why and how Hurricane Katrina and other hurricanes occur. Hopefully, in the future civilians will know and use this information to their advantage against hurricanes.
