INDIA: EARTHQUAKES India is a country ravaged by some of the worst earthquakes in history.  In the past 100 years there have been 4 destructive earthquakes.  In 1934 at Bihar Nepal, a quake measuring 8.4 on the Richter scale killed 10,700 people.  In 1950, a quake in Assam, measuring 8.7, killed 1530 people.  In 1993, in southern India, a quake measuring 6.3 killed 9,748 people. The most recent and most deadly occurred January 26, 2001.  It registered 7.7.  At least 20,085 were killed and 166,836 were injured.  Approximately 339,000 buildings were destroyed and 783,000 damaged in the Bhuj-Ahmadahad-Rajkot area and other parts of Gujaret.  Many bridges and roads were damaged.  The earthquake occurred along an east-west thrust fault at shallow depth. It was felt throughout northern India and much of Pakistan. The Richter Scale goes from 0 to greater than 9.  These numbers are used to describe the strength based on the amount of destruction.  Each whole number represents an earthquake 10 times greater than the number before it.  An earthquake measuring 6 is 10 times greater than a 5 and 100 greater than a 4. 1. Even though the quake of 1950 registered 2.5 higher than the quake of 1993, it killed less people.  How many fewer did it kill?  What could be an explanation for this? 2. The 3 earthquakes of the 20th Century caused how many deaths?  How many more is this than the quake of  the 21st Century? 3. The potential for damage in the 1934 quake was about __________ times greater than the quake of 1993. 4. A quake measuring 8.1 has potential to do about ___________ times more damage than an quake measuring 5.1. 5. How many people less than a quarter million were killed or injured in the quake of 2001? 6. Make a bar graph showing the Richter Scale readings for each of the earthquakes.  Start your scale at 6.  Remember to leave extra space. Earthquake Solutions Back to Melting Pot Math
