## What do you learn in Seismology

Seismology explores the science of earthquakes and Earth's structure. You'll study seismic waves, their propagation through the Earth, and how they reveal information about the planet's interior. The course covers tectonic plate movements, fault mechanics, and seismic hazard assessment. You'll also learn about seismometers, data analysis techniques, and how to interpret seismograms.

## Is Seismology hard?

Seismology can be challenging, especially if you're not a math whiz. It involves a fair amount of physics and calculus, which might make some students sweat. But don't worry, it's not all number crunching. The concepts are pretty fascinating, and once you get the hang of it, you'll be reading seismograms like a pro. Just be prepared for some brain gymnastics and late-night study sessions.
