Abstract
A new application of the folded pendulum as a tiltmeter is proposed and its response to the crustal vibrations is studied. Theoretical analysis shows that the folded pendulum is very sensitive to the low-frequency components of the crustal tilt vibrations. Preliminary experimental results show that the resolving power of the folded pendulum to the tilt tides is in the orde r of about 3.5 x 10(-9) rad. (C) 1999 Elsevier Science B.V. All rights rese rved.
