The document discusses the 2010 earthquakes in Chile and Haiti, detailing their impacts and causes. The Chile earthquake, with a magnitude of 8.8, resulted in 533 deaths and significant economic losses of $30 billion, primarily due to the convergence of tectonic plates. In contrast, the Haiti earthquake, with a magnitude of 7.0, caused between 316,000 and 300,000 deaths and substantial infrastructural damage, exacerbated by poor building standards and urbanization.

● Lack of national experts,
● Lack of coordination in government bureaucracy,
● Urbanization, abundance of non-engineered buildings,
● Inadequate engineered buildings
● Absence of codes and standards (CUBiC - 1985)
