I am writing a story called Life on Kepler Bb. It is about this earth like planet with 4 moons orbiting a double binary star and the humanoids that live on it. The planet has tectonic plates so earthquakes do happen
I have gotten through lots of events. Here is just a fraction of those:
First shelter built
First trip to the arctic
And this is over 10 chapters that could easily be expanded.
Anyway I was thinking of having the 11th chapter be about a severe natural disaster that the humanoids haven't survived before. I am not sure what natural disaster though. I do know that this is far inland so it wouldn't be a hurricane or any other oceanic natural disaster.
The humanoids in my story have survived severe thunderstorms and the first pirate has survived very rough waters including the roaring forties.
Maybe a description of their civilization would help.
Each male humanoid builds a shelter for him and his eventual wife. Once the male marries a female they start expanding their home both on the surface and underground to have sleeping chambers, children's rooms, etc. These homes are also connected to each other via underground tunnels. They use static electricity with positive charge to keep the civilization from crumbling and to waterproof their shelter so they don't get soaking wet inside when it rains. This also protects them from lightning strikes.
They don't have anything as far as tornado protection is concerned but they have survived tornadoes. They have also survived the worst of blizzards.
These humanoids don't have the power to survive in extreme heat(Hotter than desert temperatures), at least not yet.
Given all of this about my world and my humanoid civilization what natural disaster is more likely to form, a volcano or an earthquake?
And given that these humanoids have a mainly underground civilization what should they do if they get an earthquake or if a volcano forms? There might not be enough time to evacuate everyone unless there are lots of humanoids with the power of flight. Even then there might not be enough time if it is a volcano forming. I know that the lava would burn through any building or home.
