3Describe the global distribution of earthquakes that have occurred in the last 7 days? [You could get an exam question like this based upon a given map!]
4Mag 5+ sinceLook at the global distribution of earthquakes with a magnitude 5 orgreater that have occurred between Is there any difference between theobserved distribution and the distribution of earthquakes that have occurred inthe last 7 days?
5Task 2 The following are elements of an earthquake hazard: Time of earthquakeDate of earthquakeExact location of epicentreFault upon which the quake occursThe magnitude of the earthquakeThe economic impact of the earthquakeThe death toll of the earthquakeFor each of the elements explain how predictable it is.
6Task 3Read the BBC article and highlight the following in different colours:LocationsDatesNumbers/ValuesAny predictionAny basis upon which a prediction is madeAny issues with earthquake prediction
8Something to think about ... earthquake frequency Are earthquakes becoming more common? Are there any patterns in the two illustration above?
9Average Frequency Magnitude Average Annually 8 and higher 1 ¹ 7 - 7.9 17 ²134 ²1319 ²13,000 (estimated)130,000 (estimated)1,300,000 (estimated)¹ Based on observations since ² Based on observations since 1990.
10Essay Question Essay Question (10) Evaluate the statement: "There were more deaths from earthquakes in the last decade than the one before so earthquakes are becoming more common."
11MagnitudeProduce notes on the following three scales of magnitude used to measure earthquakes: Richter Scale, Moment Magnitude Scale and the Modified Mercalli Scale.
