Twin Earthquakes in Venezuela Could Claim Up to 100,000 Lives, USGS Estimates

The US Geological Survey (USGS) has estimated that the death toll from twin earthquakes that struck Venezuela could potentially reach 100,000. The assessment is based on data indicating that buildings in the affected area are highly vulnerable to seismic shaking.

Venezuela was hit by two powerful earthquakes, which the USGS recorded at magnitudes of 7.2 and 7.5, occurring just 39 seconds apart. Venezuela’s interim president, Delcy Rodriguez, announced in a press conference early Thursday (25/6) that at least 32 people had been confirmed dead and over 700 others injured.

USGS warned that the casualty figures could rise significantly because many structures in the impact zone are constructed from unreinforced brick and adobe block, materials that are particularly susceptible to strong ground motion. “High casualties and extensive damage are probable and the disaster is likely widespread,” the USGS stated. “Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. The most vulnerable building types are unreinforced brick and adobe block construction.”

Recent USGS analysis indicates a 33 per cent probability that the death toll could range between 1,000 and 10,000, and a 42 per cent probability for a toll between 10,000 and 100,000. These figures are statistical estimates intended to support emergency planning and are not confirmed casualty counts.

The epicentres of the twin quakes were located in Yaracuy state, west of Caracas. The areas of Altamira and El Pariso in the capital were reported to be the worst affected, with damage also reported in La Guaira and other parts of central Venezuela. Kenneth O’Dell, an experienced structural engineer from MHP Structural Engineers, told CNN that many buildings in Venezuela are older structures built to previous construction standards, making them prone to collapse.
