Bam Earthquake of 2003
Transcript of Bam Earthquake of 2003
This earthquake killed 31,824- 43,00 people out of 142,376. This left up to 75,000 people without shelter in cold December and January weather. Many people became ill from withdrawal from smoking. The government aided by providing everyday facilities and tents that provided almost no protection against the cold winds in Bam.
Ripples from the Bam earthquake led aftershocks from Los Angeles to San Francisco (USA). 3 foreshocks occurred before the mainshock, The first being 14.5 hours before the mainshock, the second being 7.5 hours before the mainshock and the third being 35 minutes before the earthquake. Damage was in a small area, roughly 16 km radius of the epicenter which is the main point of where the earthquake ensued.
95% of buildings were 60-100% destroyed. This is because the houses are crafted with mud . 3 hospitals and 122 health care centers were demolished or badly damaged.Cotton and silk industries were destroyed and the unemployment rate dropped 25%.
Bam is an Oasis town with date palm,ornage,eucalyptus and oleander trees.Most of these trees were destroyed which impacted Irans income on oranges and dates.

Tectonic plates, Seismic waves, The Richter scale and shocks
What causes earthquakes?
Where do earthquakes typically occur and why?
Most places that are prone to earthquakes are countries near the borderline of the Pacific ocean e.g. Japan, Alaska, Chile etc. Other places that earthquakes can occur are places with faults in the earths crust.
What problems are generally caused by earthquakes?
A series of vibrations in the earths crust inducing mass destruction created by the tectonic plates shifting together.
There are a few major tectonic plates such as the African and North American plates. Along with these major plates also come small ones. The plates make the earth's outer shell called the
This includes the crust and the upper part of the mantle.
There are 3 types of seismic waves
. Primary and Secondary are the two types of body waves.Primary waves are the fastest waves that occur during an earthquake. The speeds of primary waves range from 1.6- 8 km per second which is incredibly fast for a vibration.The primary waves can pass through a solid, liquid or gas. Secondary waves (also called shear waves)can only pass through solid earth crust. Unlike primary waves, secondary waves pass through solids and are stopped at the liquid layer in the earth's core. These secondary waves are also like another type of body wave only slightly less stronger inducing the name secondary wave. Surface waves (also called long waves) move along the suface of the earth. This wave is responsible for most of the earthquakes carnage to the area. These waves are also the slowest of all waves meaning they come last and the most intense.
When you throw a pebble or small rock into a lake, it creates waves in the water. An earthquake does the same thing with energy.
The Richter scale
is the graph that measures the magnitude of an earthquake. It was created by Charles F. Richter in 1934.
There are 3 types of shocks.
Foreshock,mainshock and aftershocks. Foreshocks are smaller earthquakes that sometimes occur before the main earthquake in the same area.Foreshocks usually occur a couple hours hours before the mainshock. Mainshock is the main earthquake with the largest magnitude that gets measured by the richter scale. Its is the most important and most intense.Mainshocks ALWAYS have aftershcoks that follow. Aftershocks are the earthquakes that occur after the mainshock. aftershcoks can travel through the oceans and land anywhere. Afterschocks can occur days,months or even years after the mainshock!
The diagram below shows an earthquakes damage before,during and after
When two blocks of the earth which are called tectonic plates slip past each other. Most earthquakes occur near the coastline of an ocean and the edges of plates.They also occur because of faults which is just another word for cracks in the earths tectonic plates.
People without shelter,food or water for weeks
About the Bam Earthquake
The Bam earthquake occured December 26th 2003 at 5:27 AM (local time) in the city of Bam in Iran. Bam is a city that is 975 km southeast of the capital, Tehran. This earthquake measured a 6.6 on the
. After this tragedy, 163 individuals were interviewed and 40 countries sent aid to Iran. In the first 24 hours, Iran did not send out search & rescue crews and an organized rubble removal.

Economic loss- 1500 million dollars
Agricultural loss- 53 million dollars
Tourism-30 million dollars
Industrial loss- 15.8 million dollars
Private business loss- 91.3 million dollars
USA raised 7.0 million dollars in aid for victims of the earthquake
