On 11 November 2025, a massive landslide at Hongqi Bridge in Sichuan Province, China occurred during impoundment of the 312 m high Shuangjiangkou Dam. A major highway bridge was destroyed.

In #Sheffield, someone has had a bad morning. Completely stuck, blocking the tram tracks. They've driven over 100 metres off road along the tracks to get to this point.

In August 2025, I recorded 104 fatal landslides, a record total number of landslides for August. 2025 is shaping up to be a terrible year for fatal landslides, with the cumulative total to that point being close to the highest year, in 2024.

A new paper in the journal Geoarchaeology (Garcia et al, 2025) hypothesises that an earthquake-induced debris flow in about 900 AD may have played a role in the abandonment of the archaeological site at Pikillaqta in Peru.

On 4 November 2025, a very large landslide in a coal waste slope at Mae Moh Mine in Thailand, causing extensive damage.
It appears that the landslide was associated with very heavy rainfall.

This enormous landslide occurred at the Mae Moh mine in Thailand at about 3 am on 4 November 2025. The trigger appears to have been heavy rainfall. Mae Moh is an enormous mine site at [18.3422, 99.7279].
The image was released by the operator, EGAT.

Holy moly - this glacier detachment in Tajikistan is WILD. It appears that there was a large piece of glacier ice much farther down the valley from a first detachment which then got pushed by a second soon thereafter. 🧵@planet.com @davepetley.bsky.social 🧪⚒️

Some videos have emerged from Afghanistan, reportedly showing landslides and rockfalls triggered by the M=6.3 earthquake early this morning. The road between Mazar and Kabul is reportedly blocked, which will impact the delivery of emergency assistance.

On 22 May 2025, the 1.4 million cubic metre Qingyang landslide in Guizhou Province, China killed 19 people. A new paper in the journal Landslides (Wen et al. 2025) shows that adverse geological conditions caused the landslide, and heavy rainfall was the trigger.

UTTERLY SURREAL LOW ANGLE GLACIER SLIDE!! 😮😱
On Saturday at 11:00 am, a 2 km-long, 25 m-high, and 150-200 m in width section detached off the Ismoil Somoni Glacier (Tajikistan) and slid down the gorge! 🧊🌊

Excited to share that the final chapter of my PhD has been published in Science Advances. We show that large post-earthquake debris flows in Wenchuan are more frequent than expected due to the large volumes of sediment stored in channels. 🏔️ www.science.org/doi/10.1126/... #landslides
The hazard of large debris flows
Large debris flows entrain sediment from extreme events like earthquakes and volcanic eruptions to form an escalating hazard.

Hurricane Melissa is bearing down on Jamaica, with many areas likely to see over 500 mm of rainfall. The impacts could be extremely significant.

It was a huge pleasure to see @mattgreencomedy.com in York last night, ably supported international podcast star the Triple-G Unit. Only Matt could discuss overheating fridges and the rhetoric of immigration in the same sentence.

I'm increasingly concerned about the potential impacts of Tropical Storm Melissa (which will become Hurricane Melissa in due course). The rainfall potential maps for parts of Jamaica are deeply worrying. Large-scale floods and landslides are likely. #Melissa #tropicalstormmelissa #hurricanemelissa

A new paper (Pedersen et al. 2026) in the journal Geomorphology describes the 10,900 years old Tupaasat rock avalanche in Greenland. This landslide had a volume that exceeded a billion cubic metres and a runout distance of 15.8 kilometres.
