Climate change might be behind powerful explosions in Siberia

The video discusses a powerful explosion in Russia that created a large crater. It was the 17th such crater discovered since 2013. Scientists used drones to create a 3D model, confirming that methane gas buildup in ice cavities causes these explosions. The source of the methane remains uncertain, possibly originating from deep within the Earth or near the surface. As Siberia's permafrost melts due to warming, methane blowouts are expected to become more frequent.

What technological advancement was used for the first time to study the new crater?

• Seismic sensors

• Underwater cameras

• Satellite imagery

• Drones for 3D modeling

What is the main hypothesis about the formation of these craters?

• Volcanic activity

• Methane gas buildup

• Earthquake-induced collapse

• Meteorite impact

What remains uncertain about the methane involved in the crater formation?

• Its environmental impact

• Its explosive potential

• Its source location

• Its chemical composition

What role does Siberia's permafrost play in the methane blowouts?

• It absorbs the methane

• It traps the methane gas

• It acts as a catalyst for explosions

• It prevents methane formation

What is expected to happen as the permafrost melts due to warming?

• No change in methane activity

• Decrease in methane blowouts

• Stabilization of methane levels

• Increase in methane blowouts
