What is seismic tomography?

Seismic tomography is a technique used to create detailed images of the Earth's subsurface by analyzing seismic waves.

Why is studying volcanic processes crucial for geoscience?

Studying volcanic processes is crucial for geoscience because it enhances our understanding of the Earth's dynamic behavior.

How does seismic tomography aid in understanding the Earth's composition?

Seismic tomography aids in understanding the composition, density, and temperature distribution within the Earth.

What does seismic tomography rely on?

Seismic tomography relies on the principles of seismic waves, typically generated by earthquakes or controlled explosions.

Why is knowledge of volcanic activity essential?

Knowledge of volcanic activity is essential for predicting and mitigating volcanic hazards, safeguarding communities, and improving emergency response strategies.

What are the two modes of seismic waves propagation mentioned in the text?

Compressional (P-waves) and shear (S-waves)

How do variations in subsurface materials affect wave velocities?

Denser materials generally result in faster wave travel, while less dense or fractured materials slow them down.

What do seismic sensors (seismometers) record in order to infer subsurface structure and composition?

The arrival times of seismic waves at different locations

What is the primary driving force for magma ascent?

Buoyancy—magma is less dense than the surrounding rocks

What are the two types of volcanic eruptions mentioned in the text?

Explosive Eruptions and Effusive Eruptions
