Summary Tilt steps similar to strain steps have been observed for earthquakes with magnitudes ranging from 2 to 8 and distances ranging from 10 to 12 000 km. Tilt-step propagation velocities from the hypocentre to the station of 1.2–3.8 km s-1 have

Summary In a system of plane parallel fractures, it is often assumed that resistance to slip on the fractures is independent of the direction of that slip. The fracture system then is transversely isotropic in its elastic properties and can be charac

Secular changes in the geocentric positions of lunar laser ranging stations will include components due to local and regional crustal deformations and tectonic plane movements. Terrestrial geodetic and geophysical methods appear to be the most timely

Assuming a relation of “b” to stress state, the possibility of globe-wide stress variation and transmission was investigated. The NOAA earthquake data file served to determine the temporal change in “b” of log N = a − bM from 1963 to 1975.

Automated amplitude and phase response of the complete seismometer-recording system is obtained from step inputs to the calibration coil. High accuracy is achieved by summing as many pulses as desired (to eliminate background noise) by a correlation

The physical arc length difference between the red and blue beam of a dual-color laser generates an error term in determining Delta-n as well as n (the refractive index) and D (the line length). Numerical ray trace examples and theoretical approximat

For a signal-to-noise ratio between 0.2 and 0.1 on the original single-component records, amplitudes for Rayleigh waves over oceanic paths of 155° at station MAT and 98° at station KIP have been determined as 12 mμ and 24 mμ peak-to-peak, respect
