Geographic Context
This cyclone event occurred near Wenzhou (approximately 13 km away) in China, an area that experiences a range of natural hazards. An estimated 3.6M people live within 100 km of the event location, placing this in the "severe" population impact tier.
Event Assessment
This event is a tropical cyclone system being tracked by meteorological agencies. Calamity.live has classified it as "high" severity with a severity value of 60. The computed Calamity Score is 76 out of 100, indicating a significant event requiring close monitoring. The primary scoring components are: population (100), historical (80), cascading (78). Data for this event was sourced from gdacs, one of the 250 scientific monitoring sources aggregated by Calamity.live.
Regional Monitoring Context
China has a documented history of cyclone events. Tropical cyclone monitoring for this region relies on data from meteorological agencies including NHC, JTWC, and regional RSMCs. Cyclone intensity forecasting considers sea surface temperature, wind shear, moisture availability, and atmospheric instability patterns.
Cascade Risk Analysis
This event may trigger secondary hazards through cascade effects. Cascade detection is an automated process that evaluates how primary disasters can trigger secondary events — for example, earthquakes triggering landslides, or volcanic eruptions causing lahars and pyroclastic flows. These secondary hazards can sometimes pose a greater threat than the initial event, particularly in mountainous terrain or densely populated areas.
