Popis:	A laser interferometer for earth strain measurements has been constructed and is described. The apparatus is designed to measure displacements down to small fractions of the laser wavelength. Measurements of length change of the interferometer arm of 10 m length were obtained during normal microseismic activity and following a distant earthquake. Some representative results of this laser application are presented.
