Indonesia Earthquake Data Analysis

Background

Indonesia sits on the Ring of Fire. Earthquakes are not unusual, but most people only see the news without ever looking at the raw data. I wanted to see the patterns straight from BMKG’s data.

Approach

• Pulled earthquake data from BMKG’s open API
• Processed and cleaned data: coordinates, magnitude, depth, timestamps
• Visualized earthquake distribution maps across Indonesia
• Analyzed magnitude and depth distributions
• Identified regions with highest earthquake frequency

Findings

• Most earthquakes occur at intermediate depths (50-150 km)
• Subduction zones south of Java and north of Sulawesi are the most active
• Shallow earthquakes (below 50 km) tend to have greater impact despite lower magnitudes

Reflection

Simple project, but it taught me something important: geospatial data tells a fundamentally different story than tabular data. How you visualize it matters as much as the statistical analysis.
