Digital routes for Indonesia’s volcanic emergencies
Indonesia’s active volcanoes sit close to large settlements, transport corridors and tourist routes. Across Java, Bali, Sumatra and Nusa Tenggara, an eruption can combine ashfall, pyroclastic flows, lahars and road disruption. A conventional road map cannot tell residents which route remains safe when conditions change after the last official bulletin.
A purpose-built evacuation route planner would combine official volcanic hazard zones, incident reports, road closures, shelter capacity and transport information in one mobile service. Residents would receive a clear instruction to prepare or leave, a route suited to their location and mobility, and alternatives if a bridge, road or reception centre becomes unavailable. The aim is a repeatable decision process, not another static map.
For Australian partners, the opportunity is both technical and regional. Northern Queensland communities around Cairns and the Torres Strait understand cyclone evacuation, fuel constraints and disrupted transport, while Australian emergency agencies have mature public-warning practices. The Indonesian context still requires local leadership, local-language communication and detailed knowledge of each volcano’s behaviour.
| Capability | Standard navigation apps | Purpose-built evacuation planner | Practical outcome |
|---|---|---|---|
| Hazard information | General location and traffic data | Layered exclusion zones, ash forecasts, lahar paths and official alerts | Fewer routes through dangerous areas |
| Changing conditions | Traffic updates and user reports | Verified agency bulletins, field reports and timestamped community observations | Faster recognition of blocked roads |
| Route choice | Usually the fastest available route | Routes adjusted for congestion, slope, mobility needs and shelter capacity | Safer and more practical journeys |
| Accessibility | Primarily smartphone-based | Offline maps, SMS or voice access, local languages and printable maps | Support for people without continuous data |
| Governance | Commercial recommendations | Public data standards, permission controls and auditable updates | Greater trust in emergency instructions |
Turning hazard data into safe journeys
Existing navigation applications optimise ordinary travel rather than life-critical evacuation. Their recommendations may direct people across a lahar channel, into ash-affected areas or towards a reception centre that has already reached capacity. An evacuation planner needs a different route-scoring system built around current volcanic risk.
The platform could ingest hazard layers maintained by the National Disaster Management Agency, provincial and district authorities, and the Volcanic Eruption Monitoring and Early Warning System. Road status, weather observations, public transport capacity and shelter availability would update each recommended route. When official information and community reports conflict, the system could identify the discrepancy and prioritise verified agency updates.
The tool should also recommend alternatives before a crisis makes options scarce. Residents could select a destination by district, mobility requirements and transport mode, then receive a primary route, a secondary route and instructions for checking in with family or community volunteers. Shelter capacity limits would prevent one location from attracting unsafe concentrations of people.
Designing for Indonesia’s diverse conditions
Indonesia’s geography makes connectivity and language central design requirements. Mountain roads, remote villages and rapid cellular congestion can interrupt digital services during an eruption. Downloadable maps, low-bandwidth mobile pages, SMS, voice messages and locally recorded radio or WhatsApp guidance would help the service continue when conventional data networks are strained.
Community knowledge is equally important. Residents often know whether a bridge is weak, a track has been damaged or an unofficial route has become impassable. The planner could accept geotagged observations through village validators, district officers and partner organisations, with source, time and verification status visible to decision-makers. Personal details should be minimised, especially where reporting an unsafe route could expose a household.
Governance must fit Indonesian emergency arrangements rather than reproduce another country’s command system. BNPB, provincial and district disaster agencies, PVMBG, the Indonesian Red Cross and local leaders would need agreed roles for alerts, validation and public communication. Regional-language prompts and terminology familiar to each community should be tested locally, while an authoritative audit trail would prevent unverified reports from being presented as official advice.
What Australian expertise can contribute
Northern Queensland offers a useful operational comparison. Communities around Cairns, the Torres Strait and coastal cyclone zones already plan for evacuation when roads, ferries and fuel supplies become constrained. Australian agencies and SES volunteers also understand public messages such as “evacuate early” and “leave immediately”. Those concepts can inform interface design, although Indonesian warning levels and local authority decisions must remain authoritative.
Australia’s geospatial, transport-modelling and emergency-communications sectors can contribute technical skills without dictating the final service. Firms and universities in Melbourne, Sydney and Canberra have experience with GIS, accessibility mapping, public information systems and simulation. These capabilities could support Indonesian partners in validating route engines, protecting personal information and connecting transport data from different agencies.
The Australian market also provides a clear partnership route. State, local and federal buyers commonly use competitive tenders, consortium bids and grant-funded pilots, giving smaller technology firms and research groups opportunities to work with established contractors. Australian Red Cross and specialist emergency-management organisations could partner with the Indonesian Red Cross on community engagement and training, while Australian suppliers join Indonesian organisations as local implementers rather than distant technology providers.
From pilot to dependable public service
A first pilot should focus on one district around a volcano where monitoring, institutional responsibility and community demand are strong. Mount Merapi’s flanks offer a demanding test because settlements, tourism and transport networks interact with several related hazards. Local disaster agencies would select priority zones and evacuation destinations, while the digital team would test official data feeds, route alternatives and communication channels during exercises and controlled simulations.
The architecture should use stable public standards for maps, alerts and data exchange. OpenStreetMap, open geospatial APIs and clear metadata rules would allow information from government, transport operators and community networks to remain usable across changing vendors. Coordinate systems also need careful handling: Australian datasets commonly use GDA2020, while many global and Indonesian feeds use WGS84, so transformation must be tested rather than assumed.
Financing must cover more than initial development. A viable model could combine an initial grant or development-funding tranche with a government service agreement for long-term operation. ICTD-ASP can support partner introductions, resource mobilisation and shared learning, while Indonesian agencies retain control over official alerts, data hosting and decisions about public release. Training for disaster officers, validators and community leaders is part of the service, not an optional extra.
A concrete path to safer evacuation
Delivery should proceed through a short feasibility stage, a limited operational pilot and a readiness review before expansion. The feasibility stage would inventory data, assign governance responsibilities and establish whether existing information can support reliable route advice. The pilot would test the service with local communities and emergency exercises, including scenarios involving poor connectivity, inaccurate reports and full shelters.
Success measures should centre on safety and inclusion: whether hazardous routes are avoided, whether residents receive actionable information quickly, whether users without smartphones can access guidance, and whether people with mobility constraints receive suitable alternatives. Independent review should examine data quality, privacy, accessibility and the performance of participating organisations.
The immediate next step is for ICTD-ASP to convene a 90-day feasibility workshop with BNPB, PVMBG, one Merapi district authority and Australian emergency-management and geospatial partners, producing a signed project scope, data inventory, budget and pilot criteria.
