摘要

作为一种自然灾害,地震对人类生命、基础设施和社会稳定构成重大威胁。为了降低这些风险,地震预报有可能提供及时的预警,并使人们能够采取防备措施。非地震活动是动态和非线性的,因此地震预测具有挑战性。本研究试图建立一个考虑到非地震活动的动态和非线性性质的地震预报框架。研究旨在结合位置和日期数据进行详细的地震预测。标签编码和缺失值估算等预处理技术将保持准确预测所需的关键时间模式的完整性。预处理数据还可通过基于优化的特征选择技术来挑选最相关的特征。为了获得最佳性能并有效捕捉复杂模式,必须对 LSTM 模型元素(如正则化强度和超参数值)进行优化调整。通过根据特定数据集属性校准模型,这种优化策略可大大提高预测准确性。LSTM 建模和嵌入式优化还将用于提高计算机效率和捕捉重要的地震活动模式。该平台将利用当前的地震数据集进行全面测试和评估,为减灾备灾的机器学习和优化方法提供启示。利用 LSTM 模型提出的 RassoNet 优化方法提高了模型的性能,从而使地震预报更准确、更及时,并利用各种指标对地震预报进行了评估(R2 分数:0.93;MSE:0.07;RMSE:0.26)。该框架提高了预测和减缓地震发生的能力,降低了对人类和基础设施的风险。

Optimization strategies for enhanced disaster management
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.
