Venezuela earthquakes: What happens in the first 72 hours?

Two powerful earthquakes, measuring magnitudes 7.2 and 7.5, struck Venezuela near La Guaira and Caracas, killing at least 235 people and injuring over 4,300, with the death toll expected to rise. A nationwide state of emergency has been declared as rescue teams race against time in the critical first 72 hours following the shallow, destructive quakes which occurred inland on the boundary of the Caribbean and South American tectonic plates.
