Focal mechanism solutions and nature of plate movements in Pakistan

Journal of Geodynamics, 1986
Abstract From the seismic point of view, the territory of Pakistan which lies between latitude 23°–37° N and longitude 61°–75° E is one of the most active zones in the world. The importance of this area lies in terms of movements of the Indian plate with respect to Eurasia on the west.

Mechanism Solution of Nepal-Bihar Eartbquake of August 20, 1988

Journal of the Geological Society of India, 1991
This paper presents the focal mechanism solution of the Nepal Bihar earthquake of August 20, 1988. Use was made of the first motions of P waves and polarization (or first motions) of S waves.

A comparison of multiple solutions of focal mechanisms

Bulletin of the Seismological Society of America, 1964
Abstract The occurrence of focal mechanism solutions of the same earthquake by different authors is examined. Of 42 instances of such multiple solutions for earthquakes which occurred around the borders of the Pacific Ocean, it is found that of 84 possible pairs of multiple solutions agreement is excellent in 8 cases, good in 13, fair in

On the focal mechanism of the Peru-Bolivia border earthquake of August 15, 1963

Bulletin of The Seismological Society of America (BSSA), 1970
The seismograms of the deep focus Peru-Bolivia border earthquake of August 15, 1963 reveal the presence of a number of conspicuous phases occurring within 15 seconds of the first P onset. These phases cannot be explained on the basis of known travel-time

Focal Mechanism Solutions of Intraplate Earthquakes and Stresses in the Lithosphere

1974
Focal mechanism solutions of 33 intraplate earthquakes are presented. These solutions, 47 additional mechanism solutions from the literature, and measurements of stress in situ indicate that the interiors of many lithospheric plates are characterized by large horizontal compressive stress. The predominance of com-pressive stress is particularly notable

Two focal-mechanism solutions for earthquakes from Iceland and Svalbard

Tectonophysics, 1977
Abstract Strike-slip solutions have been obtained and are presented here for the focal mechanisms of one earthquake from Iceland and one from Svalbard, on 13 and 18 January 1976, respectively. A fault plane is suggested for the Iceland earthquake.

Focal mechanism solutions and dynamic parameters of earthquakes in the eastern Himalayas and northern Burma

Tectonophysics, 1983
Abstract Focal-mechanism solutions of four earthquakes in the eastern Himalayas and northern Burma are determined using the first motion of compressional waves. Two possible solutions thus obtained for each event reveal steeply dipping fault with predominantly strike-slip motion.

Focal mechanism and source depth of earthquakes from body- and surface-wave data

Bulletin of The Seismological Society of America (BSSA), 1971
The determination of focal depth and other source parameters by the use of first-motion data and surface-wave spectra is investigated. It is shown that the spectral ratio of Love to Rayleigh waves (L/R) is sensitive to all source parameters.

Focal mechanism solution of the Himalayan earthquake of February 14, 1977

Tectonophysics, 1982
Abstract Through a closely spaced local network of seismic stations in Himachal Pradesh, India, supplemented by worldwide P-wave first-motion data, the source mechanism of the February 14, 1977 earthquake which occurred very close to the Rawalpindi area in Pakistan has been determined.

Focal mechanism solutions for Albanian earthquakes for the years 1964–1988

Tectonophysics, 1994
Abstract Focal mechanism solutions for 175 Albanian earthquakes of Albania for the years 1964–1988 were obtained by using an interactive computer technique. The results obtained are elaborated upon by applying Fisherian statistical analysis to obtain parameters for the mean stress direction in five zones.
