Why was the Chilean earthquake of magnitude 8.8 less deadly than the Haitian magnitude 7 earthquake?

Chile is a well developed country with a history of earthquakes. As such the Chilean building regulations incorporate rules specifying that buildings must be earthquake resistant and just as importantly, these rules are enforced.
Haiti on the other hand is a much poorer country where the construction regulations are not well enforced. This meant that in Haiti poor building practices were followed - e.g.insufficient steel reinforcement in concrete, the use of cheap or poorly sourced aggregates which reduce the strength of concrete or the construction on poor founding materials without the requisite foundation engineering which all acted to increase the damage caused by earthquake. As such the buildings were not earthquake resistant and so a significant number collapsed leading to the significantly higher loss of life in what was a lower magnitude earthquake.
For more information on the two earthquakes and on the factors that effect the damage an earthquake can cause, please see the related questions.

How deadly was the earthquake in Haiti?
300,000 thousand people died as a result of poor housing structures and not completely as a result of the magnitude of the earthquake.
What is the stongest earthquake?
on the Richter scale. This is the strongest earthquake ever recorded by instruments in the world. On the previous day, an earthquake with a magnitude of 7.5 struck the city of Concepción which is north of Valdivia.The second strongest earthquake in the world occurred on December 26 2004 and had a magnitude of 9.3. The epicenter was on the ocean floor near the west coast of Sumatra, Indonesia and caused a deadly tsunami in the Indian Ocean.The third strongest earthquake occurred on Good Friday, March 27, 1964 in Alaska, an earthquake with a magnitude of 9.2 struck Prince William Sound and caused extensive damage in Anchorage.Cause of the 1960 Great Chilean EarthquakeThere is a subduction zone where the Chile Ridge oceanic plate is slipping under the South American plate. This was a thrust earthquake because the Chilean Ridge plate moved downward. The epicenter was on the floor of the Pacific Ocean, approximately 100 miles off the coast of Chile.Read more at Suite101: World's Strongest Earthquake: Disaster Struck Valdivia Chile on May 22 1960http://earthquakes.suite101.com/article.cfm/worlds_strongest_earthquake#ixzz0h416oDiTMarwa rote thizzz!!!! :)
What is the Second worst earthquake ever?
The second strongest earthquake in the world occurred on December 26 2004 and had a magnitude of 9.3. The epicenter was on the ocean floor near the west coast of Sumatra, Indonesia and caused a deadly tsunami in the Indian Ocean
Why do some earthquake with small magnitude result in more death than earthquake with lager magnitude?
There is no direct correlation between deaths and magnitude. It all depends on the earthquake's location in terms of population areas, and depth.A 6.5 magnitude quake directly under a large city, might kill 50,000, but an 8.5 magnitude quake situated slightly further away from the city might only kill 500 or so.
Why was the Japan earthquake so deadly?
First reason the "earthquake" in Japan on March 11, 2011 so was deadly because it was preceded and followed by many other earthquakes nearly equally as damaging. On Thursday March 10 a series of aftershocks rattled Japan (including a magnitude 6.6 quake) after the magnitude 7.3 quake hit the northeastern Honshu island March 9, said the Japan Meteorological Agency. On March 11 alone, there were 200+ aftershocks. From the 9.0 magnitude earthquake on Friday March 11 05:46:23 UTC until March 31 midnight there were approximately 2,806 earthquakes ranging in magnitude 3.9 through 7.9. Second, the large 9.0 earthquake triggered the massive tsunami that devastated large parts of the Japan coast.
How many people can one earthquake kill?
The most deadly earthquake to date was a magnitude 8.0 quake located near the capital of Shaanxi (Shensi), China in 1956 that killed more than 830,000 people. A major earthquake in a densely populated area such as in a large city can do the most damage to human life.
Was the earthquake deadly to humanity and nature?
Yes!
What was the strongest earthquake that hit the country in the first millennium?
Modern earthquake records are typically after the 1900s. In the first millennium there were a handful of deadly earthquakes that were recorded. One in particular was in the year 869 A.D. in the Tōhoku region, Japan which was estimated to be of magnitude 8.6-9.0 very much like the earthquake that hit the same area in March 2011.

after shocks can be deadly - sometimes as bad as the earthquake itself!
