Earthquake Explorer

Global Seismic Archive & Real-Time Earthquake Explorer

Advanced geospatial analysis tool for disaster risk monitoring and historical seismic data retrieval.

Abstract: Accessing accurate earthquake data is fundamental for geological research and disaster management. Unlike standard lists restricted by administrative names, this tool utilizes coordinate-based spatial filtering. Researchers can define custom polygons to analyze seismic events across tectonic plates, border regions, and maritime zones with precision.

Why use the Polygon Tool?
Earthquakes do not respect national borders. Standard country searches often exclude critical data in borderlands and offshore epicenters. Use the map toolbar (top-left) to draw a precise area for scientifically accurate results.

Methodology and Data Integrity

This platform aggregates real-time and historical seismic data directly from the U.S. Geological Survey (USGS) Earthquake Hazards Program. It is designed to assist seismologists, disaster risk managers, and academic researchers in overcoming the "epistemic uncertainty" of location-based text searches.

• Spatial Querying: By using the Ray-Casting algorithm within the polygon tool, users can filter datasets based on geodetic coordinates rather than arbitrary administrative boundaries.
• Data Export: The CSV export function provides raw data (Time, Hypocenter Depth, Magnitude, Coordinates) suitable for further processing in GIS software (e.g., QGIS, ArcGIS) or statistical tools (Python/Pandas, R).
• Coverage: The dataset encompasses global seismic events, enabling comparative analysis of fault lines such as the North Anatolian Fault, San Andreas Fault, and the Ring of Fire.

*Disclaimer: This tool is an independent interface for public USGS data and is intended for educational and research purposes. Official disaster response decisions should always rely on local civil protection authorities (e.g., AFAD, FEMA, JMA).
