What to know about ‘doublet’ earthquakes like the destructive pair that hit Venezuela (opens original article in a new tab)

Venezuela experienced a destructive doublet earthquake sequence with magnitudes 7.1 and 7.5, causing significant casualties and damage, as scientists analyze the complex fault system involved.

• Two earthquakes struck Venezuela 39 seconds apart, with magnitudes 7.1 and 7.5, described as a doublet sequence.
• The rapid succession likely increased destruction, resulting in 188 deaths, 1,520 injuries, and 150 missing persons.
• Researchers are studying the complex fault system between the South American and Caribbean tectonic plates to understand the quakes' impact.
