Te magnitude 7.0 trzęsienia ziemi that struck Haiti on January 12, 2010, was one of thee delliest of natural disasters in modern history, with estimated death ranging frem 220,000 to 300,000. The cauphic toll result from a combination of factors: thee thistake experer thee densely populated capital city of Portau- Prince, buildings were poorly constructed with littlie or no seismic desin, and thee country 's limited hamped reatre.
