Borehole seismic methods for opencast coal exploration [PDF]

open access: yes, 1990
Surface seismic techniques lack the resolution to image the top 100m or so of the earth's surface necessary for opencast coal exploration. The work reported in this thesis is the development of borehole seismic methods making use of the closely spaced ...

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Study on Prevention and Control of Mining Disaster and Mechanical Behavior of Deep Steep Coal Seam

open access: yesMeikuang Anquan, 2020
In view of the problems such as large-scale dynamic disaster, high degree of destruction and difficult prevention and control in deep coal mining, the theoretical analysis method is adopted. Firstly, based on the micro-seismic data of coal and rock mass

Inversion of seismic reflection data from the Gialo Field, Sirte Basin [PDF]

open access: yes, 1996
This project is concerned with the development of software to invert seismic reflection data for acoustic impedance, with application to the YY-reservoir area in Gialo Field, Sirte Basin.

Three-dimensional tomographic inversion of combined reflection and refraction seismic travel-time data

open access: yes, 2003
A tomographic inversion method is presented for the determination of 3-D velocity and interface structure from a wide range of body-wave seismic traveltime data types.

3D velocity-depth model building using surface seismic and well data [PDF]

open access: yes, 1998
The objective of this work was to develop techniques that could be used to rapidly build a three-dimensional velocity-depth model of the subsurface, using the widest possible variety of data available from conventional seismic processing and allowing for

Приложение дробной модели деформационной активности к исследованию свойств эредитарности и нестационарности сейсмического процесса в зоне субдукции Курило-Камчатской островной дуги в фазе релаксации

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
Исследование свойств эредитарности и нестационарности сейсмического процесса в фазе релаксации проводится на основании данных каталога землетрясений КФ ЕГС РАН (01.01.1962 − 31.12.2002, зона субдукции Курило-Камчатской островной дуги).

Definition of seismic and tsunami hazard scenarios by exploiting EU-India Grid e-infrastructures [PDF]

open access: yes, 2012
Seismic hazard assessment can be performed following a neo-deterministic approach (NDSHA), which allows to give a realistic description of the seismic ground motion due to an earthquake of given distance and magnitude.

Seismic data reveal eastern Black Sea Basin structure [PDF]

open access: yes, 2005
Rifted continental margins are formed by progressive extension of the lithosphere. The development of these margins plays an integral role in the plate tectonic cycle, and an understanding of the extensional process underpins much hydrocarbon ...

Предвестники землетрясений в теории критичности геодеформаций

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
Предвестники землетрясений рассматриваются как резонансные проявления критических геодеформаций, дислокационные изменения которых отвечают за аномальные свойства, как самих деформаций, так и порожденных ими физических процессов, играющих роль индикаторов
