Thrust faulting and crust--upper mantle structure in East Australia
Autor: Thomas J. Fitch, Joseph M. Mills
Publikováno v: Geophysical Journal International. 48:351-384
Summary. The mid-crustal earthquake of 1973 March 9 (mb= 5.5, h≤ 20 km) located 60 km south-west of Sydney, Australia, provides unambiguous evidence of contemporary thrust faulting in South-eastern Australia — a region of high heat flow and Cenoz

Depths to Larger Earthquakes Associated with Crustal Loading
Autor: K. J. Muirhead, Thomas J. Fitch
Publikováno v: Geophysical Journal International. 37:285-296
Summary Twenty-eight earthquakes associated with reservoir filling at Koyna (Western India), Kariba (Rhodesia) and Kremasta (Greece) are with one exception relocated at mid-crustal depths or deeper. Depth resolution is achieved by a master earthquake

Seismotectonic implications of relocated aftershock sequences in Iran and Turkey
Autor: James Jackson, Thomas J. Fitch
Publikováno v: Geophysical Journal International. 57:209-229
Summary. Six aftershock sequences in Iran and Turkey are relocated using existing teleseismic data. Two of these are in the Zagros mountains where local fieldwork has failed to detect subcrustal seismicity but published teleseismic locations show dep

Inversion for VP/Vs in Shallow Source Regions
Autor: John M. W. Rynn, Thomas J. Fitch
Publikováno v: Geophysical Journal International. 44:253-267
Summary A scheme for joint location of a group of closely-spaced earthquakes has been evolved to give estimates of the ratio of compressional to shear velocities in the source region. Solutions with synthetic data support a claim that nearly unbiased

Estimation of the seismic moment tensor from teleseismic body wave data with applications to intraplate and mantle earthquakes
Autor: Thomas J. Fitch, Douglas W. McCowan, Michael W. Shields
Publikováno v: Journal of Geophysical Research: Solid Earth. 85:3817-3828
Amplitude data from direct and near-source reflected phases are inverted to obtain point-source moment tensors. The inversion scheme is computationally efficient, and the results can be interpreted without the uniqueness problems that plague many geo

An intermediate depth earthquake beneath Tibet: Source characteristics of the event of September 14, 1976
Autor: Wang-Ping Chen, Peter Molnar, Thomas J. Fitch, John L. Nábělek
Publikováno v: Journal of Geophysical Research: Solid Earth. 86:2863-2876
This paper presents the results of a detailed study of an intermediate depth earthquake beneath southern Tibet (September 14, 1976; 0643:51.6 UT; 29.8l°N, 89.57°E; focal depth 90±10 km; mb = 5.4). From the differences in arrival times of P, pP, an

Basement faulting and the focal depths of the larger earthquakes in the Zagros mountains (Iran)
Autor: James Jackson, Thomas J. Fitch
Publikováno v: Geophysical Journal of the Royal Astronomical Society. 64:561-586
Summary. The present day seismicity of the Zagros seems to occur on high angle reverse faults distributed across the whole width of the belt. It does not indicate activity on a single inclined thrust surface and there do not seem to have been any wel

Compressional velocity in source regions of deep earthquakes: An application of the master earthquake technique
Autor: Thomas J. Fitch
Publikováno v: Earth and Planetary Science Letters. 26:156-166
The technique of earthquake location relative to a master event is used to estimate near-source velocity and take-off angles for rays travelling to selected stations. Computations of a reconnaissance nature were carried out with arrival times of P an

The foreshock sequence of the February 4, 1975, Haicheng Earthquake (M = 7.3)
Autor: Thomas J. Fitch, Biquan Wang, Lucile M. Jones, Shaoxie Xu
Publikováno v: Journal of Geophysical Research: Solid Earth. 87:4575-4584
We have examined the locations and radiation patterns of the foreshocks of the February 4, 1975, Haicheng earthquake (M = 7.3). Using arrival times from six local seismic stations, the foreshocks and mainshock were located relative to a master event.
