Insights from the 06 February 2023 Mw 7.8 Kahramanmaras earthquake: evidence into an active strike-slip faulting along the East Anatolian Fault Zone
Springer Science and Business Media LLC - Tập 58 - Trang 465-497 - 2023
Makrem Harzali, Emna Medhioub, Mohamed Mansour Abdelmalak, Abdelkader Hamdouni, Habib Troudi
On February 6, 2023, a magnitude 7.8 earthquake and subsequent strong seismic activity struck in Kahramanmaras region, causing over 50,000 deaths in Turkey and Syria. The earthquake resulted in a surface rupture of the East Anatolian Fault Zone (EAFZ) spanning approximately 300 km. To gain new insights into the neotectonic and current stress field in the region, we compiled 141 focal mechanism sol...... hiện toàn bộ
Sine series expansion of associated Legendre functions
Springer Science and Business Media LLC - Tập 50 - Trang 243-259 - 2015
Lóránt Földváry
The most regularly used mathematical tools for representing the geopotential globally are the spherical harmonics, which consists of the longitude-dependent Fourier transform and of the latitude-dependent associated Legendre functions. While the former is by definition a Fourier series, the latter also can be formed to that. An alternative formulation for the sine series expansion of associated Le...... hiện toàn bộ

An application of AVO derived attributes to analyze seismic anomalies of gas hydrate bearing sediments in Makran offshore, Pakistan
Springer Science and Business Media LLC - Tập 51 - Trang 671-683 - 2015
Muhammad Irfan Ehsan, Nisar Ahmed, Zia Ud Din, Perveiz Khalid, Liu Xue Wei
The presence of gas hydrates in Makran area of Pakistan is confirmed by seismic evidences in the form of a strong reflector known as bottom simulating reflector (BSR). Amplitude versus offset (AVO) analysis is performed to analyze seismic behavior of free gas zone beneath BSR. This analysis is carried by considering a free gas zone beneath a gas hydrate-bearing zone and overlying a fully water sat...... hiện toàn bộ
Estimation of physical height changes from GRACE satellite mission data and WGHM over Turkey
Springer Science and Business Media LLC - Tập 55 - Trang 301-317 - 2020
Emel Zeray Öztürk, Walyeldeen Godah, Ramazan Alpay Abbak
Gravity Recovery and Climate Experiment (GRACE) satellite mission had provided gravity data for ca. 15 years, completed its mission in 2017 and handed over to GRACE Follow-On. During its active life, GRACE contributed to the understanding of temporal variations of geoid/quasigeoid heights as well as vertical and horizontal displacements of the Earth’s surface induced by mass loading, and thereby t...... hiện toàn bộ

Ground motion estimation during 25th April 2015 Nepal earthquake
Springer Science and Business Media LLC - - 2016
J. Dhanya, Maheshreddy Gade, S. T. G. Raghukanth
In the absence of an array of strong motion records, numerical and empirical methods are used to estimate the ground motion during 25th April 2015 Nepal earthquake. Spectral finite element method is used to simulate low frequency displacements. First, the simulated ground displacement is compared with the recorded data at Kathmandu. The good agreement between the comparisons validates the input so...... hiện toàn bộ

Evaluation of the seismicity for the Marmara region with statistical approaches
Springer Science and Business Media LLC - Tập 49 Số 3 - Trang 265-281 - 2014
Sayil, Nilgun
The Marmara region has been divided into six sub-regions having regard to the certain seismotectonic characteristics of the region, to study the seismicity. For this, the data belonging to both the historical and instrumental period has been used. The probabilities of earthquake recurrences were obtained by using Poisson statistical distribution models. Gutenberg–Richter (GR) relationship for each...... hiện toàn bộ
