Therefore, ongoing monitoring of volcanic processes is crucial for effective analysis and observation of volcanic activities preceding an eruption. In response to this, the study presents a novel hybrid time series approach, integrated with machine learning techniques, to enhance the identification and classification of seismic events associated with volcanic eruptions. In this case, time series techniques, including STA/LTA, template matching, and autocorrelation, were implemented to facilitate the detection and classification process. The challenges, however, lie in addressing noise and ensuring accuracy in the analysis of seismic signals. To resolve this, a new hybrid time series method was proposed to improve signal analysis accuracy by integrating multiple time series techniques. In practice, the dataset was collected from Mount Merapi in Indonesia between 2019 and 2021, consisting of a compilation of seismic data categorized by event type, thus enhancing classification accuracy. On top of that, prior to implementing machine learning techniques for signal classification, the hybrid method was employed to efficiently remove noise, ensuring that genuine seismic events were clearly distinguished from spurious signals. Notably, the experimental learning rate was set at 0.01. The results demonstrated that the proposed hybrid method outperformed stand-alone time series techniques, achieving an accuracy of 0.93 to 0.95. This signifies the effectiveness of precise seismic event recognition and categorization, greatly enhancing the volcano monitoring system. Furthermore, the findings offer substantial improvements in the forecasting and risk mitigation associated with volcanic eruptions, hence, advancing reliable seismic analysis methodologies. Ultimately, the method enhances hybrid methods and machine learning for seismic event analysis and volcano monitoring.  \nKeywords: Seismic Events; Hybrid Time Series; Machine Learning; Volcano Eruption.  \n1. Introduction  \nIndonesia is situated in the convergence of three tectonic plate boundaries and occupies a geographically unique position referred to as the Ring of Fire (ROF), characterized by intense tectonic activity, leading to numerous active volcanoes in Indonesia, including [1] approximately 130 active volcanoes, from Sabang to Merauke [2]. This geographical position significantly increases the potential for spontaneous volcanic eruptions, such as the eruptions recorded in one of the active and hazardous volcanoes in Indonesia, Mount Merapi [3, 4] .  \n* Corresponding author: [ashari@ugm.ac.id](ashari@ugm.ac.id)  \n [http://dx.doi.org/10.28991/HIJ-2025-06-01-08](http://dx.doi.org/10.28991/HIJ-2025-06-01-08)  \n􀂾 This is an open access article under the CC-BY license ([https://creativecommons.org/licenses/by/4.0/](https://creativecommons.org/licenses/by/4.0/)) .© Authors retain all copyrights.  \nAs illustrated in Figure 1, Mount Merapi volcano, located in Central Java, is marked by densely populated slopes, where many residents live as close as 28 km (17 miles) north of Yogyakarta, the city near Mount Merapi with a population of 2.4 million.
