Alaska Earthquakes Cases - Free Essay Example

  There are so many things happening in our world that its hard to keep up with everything that going on. One thing that not many know about are the earthquakes in Alaska. Lots of people are surprised to find out that Alaska has earthquakes. Though Alaska is actually pretty used to earthquakes. Alaska records an average of 40,000 quakes every year. Earthquakes in Alaska date all the way back to 1899. The earthquakes happen because parts of Alaska sit of fault lines. Fault Lines is a fracture along which the crust has moved. Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs. Right now in Alaska they are having some major earthquakes. These earthquakes can go all the way up to 7.0 magnitude. These Earthquakes occurred on November 30, December 1, and December 4. All of these earthquakes are about 3 to 12 miles from Anchorage. These earthquakes have had a major aftermath on the roads. The damage on the roads range from large cracks to fall and caving in of the roads. More than 1,000 aftershocks have shaken Alaska since the magnitude 7.0 quake last week. While the majority of the aftershocks were measured at magnitude 2.5 or less, about 350 small earthquakes were higher than 2.5 and around a dozen registered higher than magnitude 4.5. The original quakes core was about eight miles north of downtown Anchorage and caused structural damage to buildings and roadways. Fortunately, no deaths or injuries were caused by the quake. There is major infrastructure damage across Anchorage, said the Anchorage Police Department. Many homes and buildings are damaged. Many roads and bridges are closed.

President Donald Trump has tweeted that the federal government will spare no expense helping Alaska after the high magnitude earthquakes. Trump on Friday tweeted you have been hit hard by a big one' and asked residents to follow officials directions.
