In #Munich, you might see (and hear, feel) this weird machine, making weird vibration and sound sweeps. This is part of the Giga-M project. Its goal is to create a detailed 3D map of the underground in Munich and surrounding areas (in total 1100 square kilometres) that will be made available as #OpenData to assist in planning geothermic plants. Switching away from fossil fuel for heating. Impressive!

A so-called Vibro Truck. A heavy metal plate is lowered to the ground and a vibration sweep is initiated. Thousands of probes are distributed all over the city that receive these sweeps, allowing to create a detailed 3D map of the underground, showing potential hot water streams that can be used for geothermics.

@jwildeboer The photo reminded me of a book I read 20-ish years ago: en.wikipedia.org/wiki/The_Hamm

@maehw I guess some of the NIMBYs opposing this research have read it too ;) But it is fiction. A Vibroseis sweep can not cause earthquakes. It however can influence precision mechanics like spinning hard drives. Which is why the sweeps are announced in the affected areas.
