Description
Java, Indonesia, has a 2020 exposure model covering approximately 40 million buildings, with about 27 million identified as vulnerable masonry residential houses. The model was developed by researchers from Geoscience Australia and others, integrating open-source and government datasets with Census data. It was published in 2026 to address a gap in understanding building type distribution for seismic risk assessment.
Use Cases
Assessing regional seismic risk based on building type and use distribution.
Informing disaster management policies and resource allocation at the village (desa) scale.
Calibrating other risk models by integrating the building exposure and uncertainty data.
Prioritizing retrofitting or reinforcement programs for vulnerable masonry residential houses.
Strengths
Covers approximately 40 million buildings across the entire island of Java.
Identifies a specific subset of about 27 million vulnerable masonry residential houses.
Provides a desa (village) scale model, which is a finer resolution for local policy.
Limitations
Relies on secondary data sources, introducing an unknown degree of uncertainty to the model.
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for specific analytical tasks.
