Science In Action Why is Afghanistan so vulnerable to earthquakes?
Sep 4, 2025
Andrew Dessler, a climate scientist from Texas A&M University, discusses Afghanistan's vulnerability to earthquakes and the urgent need for better infrastructure and public education. Alongside Anne Churchland from UCLA, they delve into how brain activity informs decision-making, using groundbreaking research on neural connections in mice. Dessler also challenges misconceptions about carbon dioxide's effects on plant growth, linking climate change to food security. Additionally, listeners learn about the latest interstellar comet discoveries and their implications for astronomical research.

Episode notes
Shallow Quakes Meet Vulnerable Villages
- Afghanistan's high earthquake tolls stem from shallow quakes hitting densely built, steep-slope villages.
- Flooding, landslides and ancient, tightly packed housing amplify destruction even at moderate magnitudes.
Shallow Focus Intensifies Ground Shaking
- Shallow earthquakes (0–10 km depth) produce stronger surface shaking because energy reaches the surface quickly.
- This explains why relatively modest magnitude events can be highly destructive in Afghanistan.
Boost Monitoring And Public Awareness
- Improve seismic monitoring and public education to reduce future casualties.
- Do install more seismic stations and run awareness campaigns so communities understand earthquakes are natural and preparable events.
