Turkey and Syria. After 11 minutes, a second earth-
quake occurred in the region. Both were very heavy
and linked with a lot of damage energy. After 6 min-
utes, the earthquake waves shake our seismograph
in the specially constructed cellar room in Germany,
nearly 2500 km far away from the epicenter in many
nations (i.e. Turkey, Taiwan, Morocco, Portugal, South
Korea, Russia, …). I presented the function of our
constructed seismograph in schools and universities
during the participation in international invention fairs.
So I could feel the interest in this special invention
realized together with youth.

A variety of physical principles are applied. These are
based on the fundamentals of mechanics, electronics
and technology. Electromagnetic induction and very
slowly oscillating pendulum systems are particularly
noteworthy.
Also a multitude of challenges had to be overcome,
which could often only be realized through unusual
procedures and craftsmanship. For example the highly
sensitive electromagnetic measuring system, an induc-
tion coil of over 60000 copper wire windings had to
be wound with a self-developed winding system using
a hand drill fixed in a metal aluminium frame.
A major difficulty was the attachment of the induc-
tion coil to the low-friction horizontal pendulum sys-
tem. Also attaching the extremely strong neodymium
magnets on both sides of the induction coil to the
seismograph frame was also a great challenge. But
we managed it!
