Planet Labs satellite imagery highlights how the Wanlixi landslide in Taiwan evolved prior to the main failure on 21 June, and how it has continued to move subsequently. On 31 July 2026 I highlighted the valley-blocking Wanlixi landslide in Hualien County, Taiwan. The location of the landslide is 23.78859° N, 121.27236° E (for machine readable […]

The 4 July 2026 landslide disaster at Cantzama in Ecuador
On 4 July 2026, 19 people were killed in a massive landslide in Zamora Chinchipe province, Ecuador. Planet Labs imagery shows that this was caused by a c.1 km long landslide that occurred 13 km upstream of Cantzama. This transitioned into a channelised debris flow that destroyed the community. On 4 July 2026, a massive […]

The July 2005 rainfall-induced landslides in Yangshan (the Yang Mountains) in China
Extreme rainfall in July 2025 triggered numerous landslides and debris flows that killed over 60 people. Between 23 and 29 July 2025, the Yanshan (Yan Mountain) [41.0, 120.0] area of Hebei Province in China suffered extreme rainfall that triggered extensive flooding and landslides. As is so often the case in China, I found it difficult to […]

Submarine landslide inventory for the 2016 Kaikōura earthquake
High resolution bathymetric data has allowed submarine landslides triggered by the 2016 Kaikōura earthquake in New Zealand to be mapped (Gnesko et al. 2026). In total 853 slope failures were identified. I rarely feature submarine landslides in this blog – they are beyond my area of expertise – but I came across a really cool […]

The valley-blocking Wanlixi landslide in Taiwan
In Taiwan, a large rockslide last month, the Wanlixi landslide, has blocked a river, creating a barrier lake with a volume of about 6 million cubic metres. In Taiwan, a large landslide has blocked the Wanli river in Hualien County. The hazard is being actively monitored by the Forestry and Nature Conservation Agency, who are […]

Landslide Exposure in the United States
A new study provides a fascinating insight into the patterns of landslide exposure in the United States. The increased focus in recent years on the socio-economic aspects of landslides has been welcome. This area of understanding has lagged behind that for other hazards, possibly in part because of the lack on interest from the insurance […]
