News Blog On Natural Disasters © Copyrighted On April 6 2009 (Bloomberg), Italy’s deadliest earthquake in almost three decades killed at least 150, leaving 1,500 people were injured. Most earthquakes occur at cracks called faults, at the boundaries where the plates meet. Faults are deep cracks in rocks, mostly caused by movement at plate margins. Deep earthquakes strike in subduction zones where two plates collide slides and one slides below the other. Shallow earthquakes mostly occur where the two plates grind past each other. The rocks may be shifted only a few centimeters, but over millions of years, this can add up to hundreds of kilometers of movement sideways, and up to 30km of vertical movement. The 6.3-magnitude tremor, which struck at 3.32am local time (2.32am BST), was the country's deadliest earthquake after the Irpinia quake in the south in November 1980, which killed more than 2,500 people. ![]()
![]() ![]() One way to prevent buildings from collapsing during an earthquake is that we can build quake-proof buildings to withstand severe shaking using reinforved concrete and deep or flexible foundations. Seismologists study earthquakes. They also examine the behaviour of seismic waves passing throughthe Earth to find out about it’s structure. Instruments called seismographs measure the intensity waves. The magnitude of earthquakes can be rated by measuring these waves. Earthquakes cannot be prevented, but sometimes can be accurately predicted. Website Steve Scherer , http://www.bloomberg.com/apps/news?pid=20601100&sid=abtgde4QxGvE , extracted on 13-02-2010.
