Determining the Best Fit Curve Waveform with Synthetic Data and Solutions to the Moment of Tensor Study Cases in the Lombok Sequence on July 28, 2018-19 August 2018

Introduction

Earthquake research has become increasingly important in recent years, particularly in regions prone to seismic activity such as Lombok. The Lombok earthquake that occurred between July 28 and August 19, 2018, was a significant event that resulted in substantial damage and loss of life. Understanding the underlying mechanisms and patterns of seismic activity in this region is crucial for developing effective disaster risk mitigation strategies and improving infrastructure planning.

This study focuses on determining the frequency filtering in earthquake waveform processing using the Isola-GUI program. The program aims to process three seismic wave components recorded in the seismogram, providing valuable insights into the nature and patterns of seismic activity in the Lombok area. By analyzing the waveform data collected from various earthquake events, researchers can better understand the characteristics of seismic waves and the geological and dynamics conditions that occur in the earth.

Background

Earthquake research involves the analysis of seismic wave data to understand the underlying mechanisms and patterns of seismic activity. The Isola-GUI program is a powerful tool used in earthquake research to process and analyze seismic wave data. The program uses the inversion method to calculate the green function and obtain a more accurate value of the seismic model. This study aims to determine the frequency filtering in earthquake waveform processing using the Isola-GUI program and to analyze the results of the study cases in the Lombok sequence.

Methodology

The methodology used in this study involves the following steps:

Data Collection: Seismic wave data was collected from various earthquake events that occurred in the Lombok area between July 28 and August 19, 2018.
Data Processing: The Isola-GUI program was used to process the seismic wave data, applying the inversion method to calculate the green function and obtain a more accurate value of the seismic model.
Filtering: Four filters (F1, F2, F3, and F4) were used to determine the optimal variant reduction value.
Plotting: The results of the inversion stage were plotted to obtain a value reduction value that is close to precision 1.
Analysis: The results of the study were analyzed to determine the frequency filtering in earthquake waveform processing and to understand the nature and patterns of seismic activity in the Lombok area.

Discussion

The results of this study provide valuable insights into the nature and patterns of seismic activity in the Lombok area. The differences in frequency and value reduction in variants between various earthquake events show that the characteristics of seismic waves can vary depending on the geological and dynamics conditions that occur in the earth. The higher variant reduction value in some events shows that the model used can represent data more accurately.

By utilizing the Isola-GUI program and applying the right inversion method, researchers can better understand the mechanism behind the earthquake and the pattern of fractures that occur. This is very important for the development of future disaster risk mitigation and better infrastructure planning in earthquake-prone areas such as Lombok.
