Two earthquakes measuring 7.2 and 7.5 struck northern Venezuela near Caracas less than 40 seconds apart, killing at least 235 people and collapsing more than 100 buildings in La Guaira. US Marine Corps Maj. Gen. Kevin Jarrard arrived to oversee American relief efforts while international teams participated in search operations. Injury figures remain disputed between reports of more than 4,000 and 4,300 wounded.
