On June 24, 2026, a magnitude 7.2 earthquake struck northern Venezuela, followed less than a minute later by a magnitude 7.5 mainshock. Collectively, the earthquakes left immense damage and loss of life across the region. In the following days, satellite land displacement maps revealed how the Earth’s surface was moving, providing information about the forces
