Heavy Rain & Landslide Alert: 137 Counties at Risk
- Taiwan is experiencing exceptionally heavy rainfall, leading to increased landslide risks, particularly in northern regions.
- Taiwan's steep terrain and frequent typhoons and rainfall events make it particularly vulnerable to landslides.
- Prolonged rainfall reduces the soil's ability to absorb further water,increasing pore water pressure and reducing the soil's shear strength. This makes slopes unstable and prone to failure.

Taiwan Heavy rainfall and Landslide Alerts – May 2024
What Happened?
Taiwan is experiencing exceptionally heavy rainfall, leading to increased landslide risks, particularly in northern regions. As of May 16, 2024, a yellow alert for streams with landslide potential has been raised to 137, impacting five counties and cities, including Shuangbei. The New Taipei disaster Response Center has strengthened its response, establishing a Level Three alert status.
Understanding the Landslide risk
Taiwan’s steep terrain and frequent typhoons and rainfall events make it particularly vulnerable to landslides. The yellow alert signifies that conditions are becoming increasingly favorable for landslides to occur. A Level Three alert at the New Taipei Disaster Response Center indicates a significant escalation in preparedness and response measures.
The risk is heightened by saturated soil conditions. Prolonged rainfall reduces the soil’s ability to absorb further water,increasing pore water pressure and reducing the soil’s shear strength. This makes slopes unstable and prone to failure.
Factors Contributing to Landslide Risk:
- Intense Rainfall: The primary driver of the current situation.
- Steep Slopes: Taiwan’s mountainous terrain.
- Soil Composition: Certain soil types are more susceptible to landslides.
- Deforestation & Land Use: Changes in land cover can destabilize slopes.
Affected Areas
Currently,the alerts focus on the following areas:
| County/City | Alert Level | Number of Alerts |
|---|---|---|
| Shuangbei | Yellow | (Specific number unavailable from source,but central to the alert) |
| New Taipei City (general) | Level Three (Disaster Response Center) | N/A – System-wide preparedness |
| (Othre affected counties/cities - data not fully detailed in sources) | Yellow | (Further details needed) |
It’s vital to note that the situation is dynamic,and the affected areas may expand as rainfall continues. Residents in mountainous areas are urged to exercise extreme caution.
