Seismic Response to Tidal Forcing in the Andaman-Sumatra Subduction Zone

The Andaman-Sumatra Subduction Zone provides a natural laboratory for investigating tidal modulation of seismicity in fluid-rich hydrothermal systems. Sambit Sahoo authored this analysis, correlating seismic catalogues with vertical tidal stress, and it was last updated on April 10, 2026. The dataset is a 1.9 MB document describing the first-ever reported tidal correlations of seismicity in this diverse tectonic region.

Use Cases

• Study tidal modulation of seismicity based on the analysis of seismic catalogues from multiple sources.
• Investigate fluid-associated deformation triggering based on the described fluid-rich environments and stress mechanisms.
• Compare global tidal triggering mechanisms based on the specific spatial conditions of fault planes in the Andaman-Sumatra region.
• Analyze the role of volumetric tidal loading based on the reported correlation with vertical tidal stress.

Strengths

• Analysis is based on seismic catalogues from multiple sources, suggesting a multi-source approach.
• The dataset is openly licensed under CC-BY-4.0.
• The document focuses on a unique tectonic region, the Andaman-Sumatra Subduction Zone.

Limitations

• The dataset is a 1.9 MB document, which is a small scale for quantitative analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
