If you still believe it is fake, set one up yourself and compare the result to other seismometers near you.
But it is, no hollow earth model exists that fits to evidence.
Such as?
The advantage to science is that you don't have to take anything at face value, you can go and check the papers yourself, starting from the fundamental ones and verify that the conclusions are valid and fitting to the data.
Then go and verify it yourself. You say you are no physicist but that you know better.
Do you know how many physicists there are in how many different countries? Any such conspiracy would include a vast amount of people and by the rule of inverse probabability to the number of people involved would end up extremely unlikely.
