When do you feel an #earthquake the most
1️⃣ Distance - The closer you are, the stronger it is.
2️⃣ Depth - The shallower the earthquake, the stronger the intensity.
3️⃣ Geology - The softer the rock, the greater the tremors.

Step away from displays and protect your head first.
Then you can think about leaving.

Earthquake danger isn’t just about how many you get.
It’s about how ready you are.

The greenest solution against landslides?
Just plant trees.
Roots bind the soil, reduce erosion, and naturally stabilize slopes.
