There have been a few recent hazardous events that could have been much worse. One of these is the 2015 magnitude 8.3 Illapel earthquake that struck 46 km offshore of Illapel Chile, about 177 miles north of the nation’s capital of Santiago. This earthquake caused a tsunami that traveled across the Pacific ocean, triggering tsunami warnings from Hawaii to Japan and to California. There is a really cool animation showing the propagation of the tsunami, which created a pattern of standing waves across the Pacific Ocean Basin about 24 hours later:
Although this event was truly a great earthquake and caused much greater shaking than the 2015 Nepal M7.9 earthquake, or the 2010 Haiti M7.0 earthquake, it resulted in about 10 fatalities. In contrast, about 8,000 people lost their lives during the Nepal earthquake and nearly 200,000 lost their lives during the 2010 Haiti earthquake.
Read the following articles, and answer the questions below:
- Why did the Chilean event result in tremendously low loss of life compared with Nepal and Haiti?
- Approximately how many people were evacuated during the tsunami warning?
- Explain one reason why Chile is so well-prepared compared with other countries like Haiti and Nepal?
