Data Handling (authentic study)

edited by Mr Johari

The Recent earthquake phenomena in New Zealand and Japan have impacted many countries globally. The frequency of the earthquakes was tracked and statistical evidence was gathered and presented in the following diagram.

Study the diagram and answer the following question.



Leading Question:
Identify a possible trend in the global earthquakes pattern based on the survey conducted by the US Geological Survey. Post your response as a posting in comment.

  1. It is affect in the pacific ring of fire then moving inward in to asia

  2. It is because of the constant plates movements under the Asian sea.

  3. Most earthquakes happen on the sea and some occurs almost at the same place as some of the earthquacks

  4. When one earthquake has strike we can expect that there will be after shocks and after shock will strike within the next few days and the after shocks usually strike at the same place or neighboring places and some times neighboring countries.

  5. These earthquakes often have aftershocks and the aftershocks often strike around the same place.

  6. The earthquakes would set off after effects and then it would happen to a neighbouring country, which would repeat the after effects again

  7. Most of the earthquakes happen nearer to the mainland of Asia, except for 3 of them

  8. When there is a big magnitude earthquake, there will be smaller earthquakes at the same location, also known as after shocks. Some deaths can't be calculated as there may be people buried underneath buildings and structures.

  9. These earthquakes happen quite close together and most of the earthquakes are below 8.0 .

  10. The earthquakes operate around the pacific ring of fire, which is a hotspot for volcanic eruptions. There, earthquakes are quite frequent. The first quakes started, which triggers a chain reaction that triggers earthquakes to it's neighboring countries. Almost each time, the magnitude increases. I can predict that another quake would hit again.

  11. Notice that southeast asia is not that affected. That does not mean that the others are safe. Australia is flooding,Outer Indonesia has volcanic eruptions. The earthquakes are heading upwards and left too. I predict that maybe India or Thailand will be struck next

  12. The places where the earthquakes start are quite near Japan, and their magnitude is 5 and above all the way to 9. The earthquakes are quite close to each other in terms of date.

  13. I can percieve that the earthquake which struck Japan will affect surrounding area because of the impact of the earthquake will radiate from Japan to affect other countries

  14. All the earthquakes are close to each other, which is probably because of the aftershocks.

  15. The earthquake seems to remain its magnitude as it travel through the sea.

  16. When an earthquake started, there would be a few subsequent earthquakes (probably because of the great magnitude of the earthquake) at some of the nearby countries/areas.

  17. These earthquakes happen near and on the sea. After an earthquake the next earthquake's magnitude is lower.

  18. When a single earthquake strikes, there will be some other countries that will be affected because the two tectonic plates that caused the earthquake caused aftershocks to the nearby countries

  19. Most of the quakes occurred during the month of March, and most of the quakes have a magnitude of 6 and above.

  20. From the listing of the magnitudes by days, 7.2, 6.3, 6.6, 7.2, 5.4, 9.0, 6.3, 6.1, 6.6, 6.8, 5.0, I realize that the first few days of the year, the earthquakes were quite bad, with high magnitudes, then after the worst earthquake, 9.0, the other trend of quakes start to subside. So, i suspect that the trend will spike up again. We should prepare for the worse, and expect the best.

  21. Two of the major earthquakes (Japan and Christchurch) are two of the four corners of the Pacific Seabed. The other 2 being San Francisco and Chile. Also some major earthquakes happen on islands.

    ReplyDelete
  22. I feel that since the date of the earthquake strike are close together, other earthquake cause others.

    ReplyDelete
  23. i think that maybe the quakes affect one another.

    ReplyDelete
  24. i feel that the magnitudes of the quakes are increasing .
