Abstract
As a natural disaster, earthquakes pose a significant threat to human life, infrastructure, and societal stability. To mitigate these risks, earthquake forecasting has the potential to provide timely warnings and enable preparedness measures to be taken. Non-seismic activity is dynamic and nonlinear, making earthquake prediction challenging. This study attempts to create a framework for earthquake forecasting that takes into account the dynamic and nonlinear nature of non-seismic activity. The research aims to make detailed earthquake predictions by combining location and date data. Preprocessing techniques such as label encoding and missing-value imputation will preserve the integrity of critical temporal patterns required for accurate forecasting. Preprocessed data can also be utilized to pick the most relevant features via an optimization-based feature selection technique. To achieve maximal performance and effectively capture complex patterns, LSTM model elements such as regularization strength and hyperparameter values must be optimally tuned. By calibrating models to specific dataset properties, this optimization strategy greatly improves forecast accuracy. LSTM modeling and embedded optimization will also be employed to increase computer efficiency and capture significant seismic activity patterns. This platform will be thoroughly tested and assessed using current earthquake datasets, yielding insights into machine learning and optimization approaches for disaster mitigation and preparedness. Proposed RassoNet Optimization approaches using LSTM model has been used to improve the model's performance, resulting in more exact and current earthquake forecasting which has been evaluated using various metrics(R2 score: 0.93, MSE: 0.07, RMSE: 0.26). The framework improves the ability to predict and mitigate seismic occurrences, reducing the risk to people and infrastructure.
期刊介绍:
Papers must have a regional appeal and should present work of more than local significance. Research papers dealing with the regional geology of South American cratons and mobile belts, within the following research fields:
-Economic geology, metallogenesis and hydrocarbon genesis and reservoirs.
-Geophysics, geochemistry, volcanology, igneous and metamorphic petrology.
-Tectonics, neo- and seismotectonics and geodynamic modeling.
-Geomorphology, geological hazards, environmental geology, climate change in America and Antarctica, and soil research.
-Stratigraphy, sedimentology, structure and basin evolution.
-Paleontology, paleoecology, paleoclimatology and Quaternary geology.
New developments in already established regional projects and new initiatives dealing with the geology of the continent will be summarized and presented on a regular basis. Short notes, discussions, book reviews and conference and workshop reports will also be included when relevant.
