Earthquake Location Uncertainty Maps for the Netherlands at 3 km Depth

A geospatial dataset modeling location uncertainty for seismic events across the Netherlands, computed over a grid with a fixed source depth of 3 km. The dataset, provided by the Ministerie van Binnenlandse Zaken en Koninkrijksrelaties, parameterizes uncertainty with standard deviations (S1, S2, SZ, T) and includes the Azimuthal gap (AG) parameter. Details are documented in a linked technical report.

Use Cases

• Modeling seismic event location probability based on multivariate normal distribution approximations described in the dataset.
• Analyzing horizontal and vertical uncertainty parameters (S1, S2, SZ, T) for sensor network planning.
• Evaluating Azimuthal station coverage (AG) for improving earthquake detection networks.
• Assessing regional seismic hazard by mapping location uncertainty across the Netherlands.

Strengths

• Includes detailed uncertainty parameters (S1, S2, SZ, T, AG) derived from probability density functions.
• Covers a grid spanning the Netherlands and incorporates sensors from neighboring Belgium and Germany.
• Based on a documented methodology with a linked technical report (TR405.pdf).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
