been struck by an earthquake. You are a scientist with the USGS and need to figure out all the specifics on the earthquake because an earthquake has never occurred here before. You have a few things to do as a person working for the USGS to keep your job as the seismologist on staff. 1. Using the 3 seismograms recorded‚ figure out the epicenter location using the data and the P/S wave time-travel graph. One of the seismograms has been done for you. 2. Determine if the earthquake came from a fault

Earthquake Resistant Bridges Jacqueline Stoy 4/24/2013 Geography of Cultural Diversity 3350:275 Tuesday/Thursday 12:05-12:55 Throughout history‚ bridges have been a primary means of transportation. Unfortunately‚ natural disasters have come to destroy such bridges on many occasions. One of the most deadly natural disasters to face the bridges is earthquakes. The movement of the ground causes the supporting beams and columns to twist and collapse‚ often resulting in injury or death for

1.Earthquakes 1. According to dictionary.reference.com an earthquake is a: Series of vibrations induced in the earth’s crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating. The earth is made up of tectonic plates these are massive slabs of rock floating on magma ‚as the plates move about‚ they spread apart‚ collide‚ or slide past each other‚ This is the main cause of volcanoes and earthquakes Earthquakes occur in many regions all over the world

March 27‚ 1964 a magnitude 9.2 earthquake hit Alaska its epicenter located in Prince William Sound‚ 75 miles east of Anchorage. This earthquake was and still is the second larges earthquake ever recorded (Christensen). The plates involved In this major earthquake were the Pacific plate and North American plate. This subduction zone is know as Aleutian-Alaska megathrust zone (Sokolowski). This region was known for its active plate tectonics‚ but this earthquake did come as a surprise to the public

“Japan earthquake: Tsunami hits north-east” Source: BBC 2‚ Horizon Special Professor Ian Stewart‚ Geologist Broadcast on 27th March 2011 In this programme‚ Ian Stewart examines the powerful geological forces that caused the devastating Japanese earthquake. 30% of all earthquakes across the world happen in Japan. Earthquakes are caused when the tectonic plates (giant slabs of rock) grind together causing the build up of huge forces. When the pressure gets too much‚ the edges of the plate suddenly

Earthquakes in Japan The Japan is located in an area where several continental and oceanic plates meet and create a major fault line; this is the cause of frequent earthquakes and the presence of many volcanoes and hot springs across Japan. If earthquakes occur below or close to the ocean‚ they may trigger tidal waves known as tsunami. Historic earthquakes Here is a brief history of earthquake in Japan. Many parts of this country have experienced devastating earthquakes and tidal waves in the

Access the measures that Caribbean countries could realistically undertake to minimize the danger posed by earthquakes. An earthquake is a sudden and violent shaking of the ground‚ sometimes causing great destruction‚ as a result of movements within the earth’s crust or volcanic action. This happens when two blocks of the earth suddenly slip past one another. The Earth’s crust is made up of about a dozen plates on which the continents and oceans rest. These plates are continually shifting because the
