Question

What is the average time time it takes to accurately determine earthquake magnitude and how did that contribute to a lack of warning in Sumatra, Indonesia in 2004

Question 22 options:

1 hour, the tsunami hit at low tide so the severity of the tsunami was underestimated

20 minutes, the magnitude was initially thought to be 7.3

1 hour, the magnitude was incorrectly initially thought to be magnitude 6.6

1 day, the magnitude of the earthquake was unknown during this time

20 minutes, the magnitude was initially thought to be 7.3

1 hour, the magnitude was incorrectly initially thought to be magnitude 6.6

1 day, the magnitude of the earthquake was unknown during this time

Explanation / Answer

1 hour, the magnitude was initially thought to be 6.6 which was incorrect.

The third largest earthquake ever recorded strikes off the west coast of Sumatra, Indonesia. With a magnitude of between 9.1 and 9.3.

But there is initial confusion over the strength of the quake. In Indonesia, the authorities say it is 6.6 magnitude while geologists in the United States say it was 8.1.

There was no tsunami warning system in the Indian Ocean to detect tsunamis or to warn the hundreds of thousands of people who lived in coastal areas.
