Analysis of Registration and Processing of Seismological Data in the Republic of Armenia from 1991 to 1998

Avetisyan Andrey Mergevosovich,Burmin Valeriy Yurievich,Petrosyan Goharik Razmikovna
Determining the coordinates of earthquakes is a priority task in seismically active regions, the accuracy of which is subject to ever-increasing demands. The accuracy and completeness of the data determine the correctness of solving prognostic and structural problems of modern seismology, as well as problems of geodynamics of seismic regions. The work analyzes the registration and processing of Republic Armenia (RA) seismological data. It has been shown that the accuracy of processing Republic A...

Experimental Research on the Movement Patterns of Flat-Shaped Block in Debris Flows

Lei Feng
Geological disasters occur frequently in China, and large-scale debris flow events have caused serious threats to people’s lives and property. Debris flow has the characteristics of high density and high velocity, especially the presence of large block in debris flow, which makes debris flow a great threat to engineering structures. In order to investigate the movement patterns of flat-shaped block in debris flow, a small-scale flume experiment with precise control was carried out. In the experi...

Study of the in-Depth Extension of Geophysical Lineaments Deduced from Magnetic Data in an Oil Block: Case of Block 10B in the Central Basin (Democratic Republic of the Congo)

Ngambua Ngambua Rene, Shakeel Hussain, Nida Jabeen, Foutou Matsoulou Ray, Ashfaq Niaz
This paper aims to study the magnetic data collected in block 10B of the central basin in the Democratic Republic of Congo. This block includes lineaments mainly of internal geodynamic origin. This is work that further deepens knowledge of the lineaments of the central basin, although analyzes and maps for oil research purposes remain complex (location, detection techniques, and enhancements). The lineaments play great importance in mining prospecting than in oil prospecting. Because often the l...

Terrain Modeling and Analysis Using Earth Observation System Based Data: A Case Study of Anambra State, Nigeria

E. Ahuchaogu Udo, O. C. Ojinnaka, A. C. Chukwuocha, U. Duru Uchenna
We met terrain as the core of our existence therefore good understanding of the topography and other environmental settings improves safety. Mapping and visualization of terrain variable are the bedrock for understanding, protection, management and meaningful development of the physical environment. Integration of remote sensing (RS) and geographic information system (GIS) techniques has proved to be force for sustainable development. Therefore, the aim of this study is to demonstrate how RS and...

Time Variations Analysis of the Geomagnetic Field in the Municipality of Macaé, Brazil

Laisa Prata Moreira Fernandes, Joao Victor Jobim de Souza e Silva, Iago Reis Homsi, Paula de Carvalho Garcia, Gabriel Teixeira de Oliveira Barroso, Tainá Rebelo e Ribeiro, Gabriel Gomes Dias de Oliveira, Vania Regina de Oliveira Branco, Hans Schmidt Santos
This paper presents the analysis of temporal variations of the geomagnetic field in the municipality of Macaé, Brazil. Current and historical magnetic field from the IGRF (International Geomagnetic Reference Field) and Gufm1 models were used to construct two-dimensional maps from 1590 to 2019. Analysis of the maps revealed that there was a large decrease in total magnetic field magnitude from around 48,000 nT in 1590 to 23,000 nT in 2019, i.e., a decrease of more than 50%. This decrease was inte...

AVO Didactic Analysis from Simplified Modeling of Seismic Data in Libra Oil Field of the Pre-Salt Region, Brazil

Kaio da Silva Pimentel Figueiredo, Kaendra Williams Temoteo, Rafael Ximenes Goncalves, Yasmim Monteiro Cordeiro, Rogério Manhaes Soares, Hans Schmidt Santos, Claudiomar Rodrigues Franco, Felipe Barbosa Venancio de Freitas, Christyne Barros de Sá
In this study, a certain zone of Libra oil field of the pre-salt region was se-lected to be analyzed for didactic purposes in order to simulate AVO re-sponses. The region was modeled using seismic data, setting up a typical oil system with source rock (shale), reservoir rock (sandstone), and seal rock (salt). Thus, a set of parameters such as seismic wave velocity, density and Poisson’s ratio for the studied zone w
