Earthquake Prediction Quiz

What did Zhang Heng claim his large vase could do?

• Predict earthquakes and the direction for aid

• Store water for the court

• Display artwork for the court

• Play music for the court

What causes deep cracks in the interacting tectonic plates?

• Gravitational forces

• High temperatures in the mantle

• Friction between rocks

• Tiny movements of the plates

What is one of the challenges in predicting earthquakes?

• The behavior of the plates is somewhat cyclical

What did nearby researchers record just before an earthquake struck the east coast of Japan in 2011?

• High concentrations of the radioactive isotope pair: radon and thoron

• A sudden increase in smartphone usage

• A decrease in the availability of Quakesim software

• An unexpected rise in the number of seismometers

What is the potential benefit of building a vast network of radon-thoron detectors in earthquake-prone areas?

• Predicting quakes a week in advance

• Recording seismic waves for research purposes

• Crowdsourcing a warning system for incoming quakes

• Enacting safety protocols for immediate response

What could help us track and predict large-scale geological changes in real time?
