The observed anomalous tilt time development of static horizontal pendulum and anomalous time development of variations (noise) before earthquakes could be the basis for possible prediction of earthquakes. This case study showed the behaviour of rock mass before main earthquakes worldwide in the years 2007 – 2009 (Peru 15.8.07 (M=8), Indonesia 12.9.07 (M=8.5+7.9), Chile 14.11.07 (M=7.7), Fiji 9.12.07 (M=7.8), Andreanoff island 19.12.07 (M=7.2), Sichuan 12.5.08 (M=7.9), Kuril islands 24.11.08 (M=7.3), Indonesia 3.1.09 (M=7.6), Tonga 19.3.09 (M=7.6), N. Zeland 15.7.09 (M=7.8), Andaman island 10.8.09 (M=7.5), Samoa 29.9.09 (M=8.1)).
