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.

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

others‚ but no matter the severity‚ there is usually a loss‚ and a cry for help. The first one I want to talk about is the earthquake that hit Haiti in 2010. By January 24th‚ at least 52 aftershocks (a smaller earthquake following the main shock of a large earthquake)‚ measuring 4.5 or greater had been recorded. An estimate of three million people were affected by the earthquake. Death toll estimates ranged from 100‚000 to 160‚000. 316 total had been affected overall. Estimated 250‚000 residences and

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

Since it first began‚ Indian Ocean commerce has been a linking force in the surrounding region. However‚ it has not all remained the same. Between 650 CE and 1450 CE‚ Indian Ocean trade routes and dominating groups changed significantly‚ while the goods they traded remained largely the same. Trade routes used by Indian Ocean mariners were important to the region’s commerce. They needed to find faster‚ easier routes to the destination. At first‚ many merchants would have to sail to far away

This article that I have chosen is a earthquake that happened in China. It was said that this earthquake had the largest measuring magnitude of 5.7. After the earthquake‚ at least 80 were killed and 700 were injured. This earthquake was the heaviest in the rural area in Yiliang country. One of the elementary school collapsed in the earthquake. Authorities are not sure if the children are killed. In 2008‚ there was an earthquake in Yunnan’s neighbouring Sichuan province‚ which killed 80
