What is Risk Analysis in context of Natural Disasters?
Natural disaster risk assessments evaluate how phenomena like typhoons impact people safety, critical infrastructure, business operations, and supply chains. They provide timely intelligence that helps organizations prepare for disruptions, mitigate operational risks, and ensure the welfare of staff and assets.
Executive Summary
- Date of Incident: 13 August 2025
- Location: Taipei, Hualien, Chiayi, Taiwan
- Risk Category: Natural Disasters
- Severity Score: 4/5
- Confidence Level: 92%
Typhoon Podul, currently impacting Southern Taiwan, is forecasted to cause significant disruption, with local authorities already initiating shutdowns. Based on historical typhoon activity in Taiwan, we anticipate a severe impact lasting approximately 3-5 days. Past events demonstrate that typhoons of this magnitude consistently lead to extensive infrastructure damage, widespread power outages, and critical transportation disruptions. The mountainous terrain and dense population centers, particularly along the eastern and southern coasts, are highly vulnerable to flooding, landslides, and wind damage. The current preparedness level, indicated by pre-emptive shutdowns, suggests a high degree of certainty regarding the storm’s immediate effects.
Known Hotspots and Sensitive Areas
Sensitive areas prone to severe impact include Hualien County and its Yuli Township, which has experienced significant disaster from past typhoon rains. The Matian’an Creek and its associated dam in Hualien are also high-risk for overflow, and the Hualien landfill could be on high alert for overflow or damage.
Impact on Transportation and Services
- Travel & Mobility: Extensive road closures, railway service interruptions, and cancellations of flights and ferry services are expected, severely restricting movement across affected regions.
- Infrastructure & Utilities: Critical infrastructure such as roads, bridges, power grids, water treatment facilities, and drainage systems are highly susceptible to severe damage, leading to prolonged outages.
- People Safety: Historical typhoons have led to injuries and fatalities, requiring large-scale mandatory evacuations, particularly in vulnerable coastal and mountainous areas.
- Business Operations: Widespread business shutdowns, employee absenteeism, and operational disruptions are highly probable due to severe weather, utility outages, and transport limitations.
- Supply Chain & Logistics: Disruptions to transportation networks, port operations, and manufacturing sites will cause significant delays in goods movement and production.
Recommended Actions
- Activate Remote Work Protocols: Immediately activate remote work protocols for all non-essential personnel in affected southern regions of Taiwan, strictly adhering to local government work/school suspension advisories.
- Implement Asset Protection: Secure all facilities against high winds and flooding. Verify backup power systems (generators, UPS), ensure critical data is backed up off-site, and prepare for potential communication infrastructure failures.
- Engage with Supply Chain Partners: Proactively engage with suppliers and logistics providers to mitigate disruptions. Activate pre-planned alternative routes, consider temporary warehousing, and ensure critical inventory is adequately pre-positioned.
- Establish Crisis Management Team: Establish a centralized crisis management team to monitor the typhoon’s progression in real-time. The communications department must issue clear and frequent updates to customers and external stakeholders.

- National Emergency: 112
Final Thoughts
The baseline scenario anticipates a slightly weakened Typhoon Podul, with moderate rainfall and strong winds, leading to localized flooding and minor power outages. A moderate escalation could see the typhoon maintain significant strength, causing widespread flooding, mudslides, and significant power outages. A severe escalation, though less likely, could intensify into a major typhoon, causing catastrophic damage, widespread infrastructure collapse, and a national-level emergency. Businesses should prioritize employee safety and have robust continuity plans to navigate this high-risk event.
