ANADEF: A Nested-Permutation Alarm for Dual-Parameter Earthquake Forecasting
Hamzeh Mohammadigheymasi, Muhammed Hossein Mousavi, Nuno Pombo
Spatially resolved stress proxies and rate-based seismicity models are increasingly combined for regional earthquake forecasting, yet formally testing their non-redundancy remains…
The 2016 Mw 7.0 Kumamoto Earthquake Sequence, Japan revisited: Insights from Spatio-Temporal Analysis of Seismicity Parameters
Hamzeh Mohammadigheymasi, Muhammed Hossein Mousavi, Marjan Tourani +1
Understanding how crustal faults accumulate strain, nucleate ruptures, and redistribute post-seismic stress is fundamental to seismic hazard assessment. The 16 April 2016 7.0…
Cross-Sectional and Spatio-Temporal Analysis of Seismicity Parameters in the Zagros Orogenic Belt: Insights into Crustal Stress Distribution and Seismic Hazard
Muhammed Hossein Mousavi, Marjan Tourani, Amir Talebi +2
The Zagros Orogenic Belt, formed by the Arabian-Eurasia collision, is a highly active collision zone hosting a large portion of Iran's seismicity. In this study, the IRSC catalog (…
Joint Analysis of Shannon and Tsallis Entropy and GRACE-FO driven Equivalent Water Height Anomalies for Pre- and Post-Rupture Monitoring: An Example of the 2023 Mw = 7.8 Kahramanmaraş Earthquake, Türkiye
Muhammed Hossein Mousavi, Hamzeh Mohammadigheymasi, Amirreza Moradi
In order to understand the variations in fault systems throughout the seismogenic cycle, mechanical states and the complexities of seismic interactions must be considered. In this…
Integrating b-Value and Background Seismicity Rate for Spatial Earthquake Forecasting in the Alborz Region, Northern Iran
Muhammed Hossein Mousavi, Hamzeh Mohammadigheymasi, Parva Sadeghi Alavijeh +1
In this study, we evaluate the spatial forecasting skill of the -value and background seismicity rate across the Alborz region using a homogenized catalog of 23,961 earthqua…
Seismic Depth Imaging of the 2024 Noto Earthquake (M7.6) Rupture Area
Hamzeh Mohammadigheymasi, Jin-Oh Park
On January 1, 2024, a moment magnitude (Mw) 7.6 earthquake struck the Noto Peninsula, Japan, causing intense ground shaking and triggering a tsunami along the Japan Sea coast. Prel…
Crustal Structure Imaging of Ghana from Single-Station Ambient Noise Autocorrelations and Earthquake Arrival Time Inversion
Hamzeh Mohammadigheymasi, Courage K. Letsa, Nasrin Tavakolizadeh +5
The crustal architecture of southern Ghana remains inadequately resolved despite its tectonic significance and resource potential. Existing geological and geophysical studies provi…
Earthquake body wave extraction using sparsity-promoting polarization filtering in the time-frequency domain
Hamzeh Mohammadigheymasi, Bahare Imanibadrbani, Ali Gholami +1
Seismic waves generated by earthquakes consist of multiple phases that carry critical information about Earth's internal structure as they propagate through heterogeneous media. Th…
Enhancement of Quantum Semi-Supervised Learning via Improved Laplacian and Poisson Methods
Hamed Gholipour, Farid Bozorgnia, Hamzeh Mohammadigheymasi +5
This paper develops a hybrid quantum approach for graph-based semi-supervised learning to enhance performance in scenarios where labeled data is scarce. We introduce two enhanced q…
A Laplacian-based Quantum Graph Neural Network for Semi-Supervised Learning
Hamed Gholipour, Farid Bozorgnia, Kailash Hambarde +5
Laplacian learning method is a well-established technique in classical graph-based semi-supervised learning, but its potential in the quantum domain remains largely unexplored. Thi…
A Cluster-Based Opposition Differential Evolution Algorithm Boosted by a Local Search for ECG Signal Classification
Mehran Pourvahab, Seyed Jalaleddin Mousavirad, Virginie Felizardo +6
Electrocardiogram (ECG) signals, which capture the heart's electrical activity, are used to diagnose and monitor cardiac problems. The accurate classification of ECG signals, parti…
