Suggestions for a "earth vibration/earth tremor" sensor and "earth magnetic feild" sensor

I have only just discovered the huge possibilities of ESPhome.
I have for a while wanted to capture some of my own raw data on 2 things, vibrations from the ground and the surrounding magnetic field.

Can anyone suggest sensors i could use for the above?

Obviously, these are home DIY projects and i am not expecting awesome reason of quality data, I just want something that will give me a rough idea of whats going on.

Maybe someone has already integrated such devices in esphome?

Did you get at least a look at sensors supported by ESPHome to find out if some can fit your request ??
