Hydrau HQ
Your central hub for natural hazard insights, tools, and services.
This is where I share everything I build to help people understand, react to, and protect themselves from natural hazards.
Understand
We can’t protect ourselves from something we don’t understand.
What are these phenomena? How do they work? What triggers them?
React
Instinct is a start. But good reflexes are built ahead of time.
Know what actions can truly save lives (and which should especially be avoided)
Protect
Protection doesn’t start when danger strikes.
From choosing the right location to taking the right steps, real protection means knowing where you’re vulnerable — and what to do about it.

Who's Hydrau?
Thomas CAMPEDEL
Natural Hazard Engineer & Natural Hazard Educator
🎓 With a Master’s degree in Natural Hazards and Geotechnical Engineering, I created Hydrau in 2022, driven by one thought:
“If the job of your dreams doesn’t exist — build it.”
Since then, I’ve been developing Hydrau to help those exposed to natural hazards — directly or indirectly.
