NASA preliminary satellite assessment estimates about 58,870 buildings damaged or destroyed after Venezuela earthquakes
The Facts
- NASA’s preliminary assessment estimated that approximately 58,870 buildings were likely damaged or destroyed in the area affected by the Venezuela earthquakes.
- The estimate was based on high-resolution Sentinel-1 radar data from the European Space Agency collected on June 25, the day after the earthquakes.
- Researchers Corey Scher and Jamon Van Den Hoek of Oregon State University said the satellite-based damage estimate was a rapid, preliminary assessment rather than a ground-verified count.
- Venezuela was struck on June 24 by twin earthquakes with magnitudes of 7.2 and 7.5.
- The earthquakes have killed at least about 1,700 people, according to multiple reports citing official figures.
- Many people remain missing or unaccounted for after the earthquakes, and search-and-rescue operations are continuing.
- The satellite estimate is far higher than the building-damage figures reported so far by Venezuelan authorities, leaving the full extent of destruction still unresolved pending field verification.
How left and right are reading this
- Both agree
- A deadly disaster is still unfolding, and the building-damage count remains consequential but unresolved while rescue efforts continue and many people are still missing.
- They split on
- Whether the story is about a possible undercount obscuring the true scale of need, or about keeping preliminary satellite estimates from hardening into settled fact.
Context
Why does NASA’s building-damage estimate differ from official counts?
NASA’s figure comes from a rapid satellite-radar assessment that detects abrupt surface changes consistent with damage across the affected region, while official counts cited in reports were based on authorities’ reported building tallies on the ground. Researchers said the NASA estimate is preliminary and has not yet been validated in field inspections, which helps explain why the totals do not match. RTBF,Observador,Anadolu Ajansı,O Povo
How was the satellite estimate produced?
The assessment used high-resolution radar imagery from the European Space Agency’s Sentinel-1 satellite collected on June 25, one day after the earthquakes. Researchers Corey Scher and Jamon Van Den Hoek of Oregon State University analyzed the data for NASA and described the result as a rapid, preliminary estimate.

Why does this estimate matter now?
With at least about 1,700 deaths reported and many people still missing or unaccounted for, a broad estimate of damaged structures helps show the likely scale of the disaster while rescue and recovery efforts continue. Because the figure covers the wider affected region and may exceed current official building counts, it suggests the destruction could be broader than early on-the-ground tallies indicate.
