A hazard and landscape briefing for Batur — how the geopark's territory intersects the InaRISK national layers, and what 24 years of satellite observation reveal about the caldera and its 21 geosites.

Batur is a caldera within a caldera. Every value here is clipped to the exact geopark polygon, so it describes this territory — not the regency around it.
Mean InaRISK index inside the Batur polygon. Layers with no coverage in the geopark are omitted.
Steep caldera walls dominate the landslide signal; the active cone drives volcanic proximity; the caldera floor and the lake collect water. The flood, tsunami and liquefaction layers have no coverage inside the Batur polygon, so they are not shown as numbers.

Each geosite carries its geological hazard and the InaRISK index sampled at its exact point. Select one on the map, or browse the list.
The InaRISK rasters describe relative hazard vulnerability on a 0–1 scale inside the geopark. They are not event probabilities and do not replace warnings from PVMBG, BMKG or BPBD.
Satellite series (NDVI vegetation, daytime land-surface temperature, burned area) are yearly area summaries for the same polygon — useful for reading condition and change over time, not for point decisions.
See the layers in the storyThe same green → yellow → orange → red ramp is reused for every hazard layer. Transparent pixels = no data.
Every figure carries its dataset, method and date. Coverage gaps are shown as “no coverage” rather than zero.
