Happy 6th "Large boulder the size of a small boulder" anniversary to those who celebrate! #Geology ⚒️
Twitter post screenshot of the San Miguel Sheriff account. 5 years ago they posted about a boulder on the road but referred to it as "Large boulder the size of a small boulder".

Suffice to say there’s evidence of excavation at the base of the slope and former landslide scarps.

The brilliant people at Planet Labs have captured an image of the 13 January 2026 landslide at Burutsi village in the Democratic Republic of Congo. This landslide killed 28 people and blocked an important road. The runout distance is about 500 metres.

I thought you may have seen this Dave. Unfortunately it does look almost certain that there will be fatalities. There has been an enormous quantity of rainfall in the Bay of Plenty and other areas in the past couple of days, including 300+mm in a day in Whitianga, with numerous slips likely.

A new paper (Jia et al. 2026) examines the underlying causes of the 8 February 2025 Junlian rock avalanche in Sichuan Province, China, which killed 29 people. Repeated wetting and drying cycles weakened the rock mass until failure could occur under unexceptional rainfall.

This stunning image shows a landslide in Sirenum Fossae, just on the edge of Daedalia Planum, where multiple lava flows have occurred. What was the geometry of the failure that caused it?

Recovery operations continue for the 36 victims of the 8 January 2026 garbage landslide at Binaliw in the Philippines. The landslide appears to have a rotational form at the crown and to have been a flow lower down.

A fascinating paper (Ozturk et al. 2025) highlights the shifting pattern of landslide risk in cities using the 2025 Granizal landslide in Medellín, Colombia. They show that climate change means that the urban rich are at increasing levels of threat alongside the poor.

The main body of the 25 June 2025 landslide at Granizal in Colombia. Still from a video posted to Youtube by Cubrinet: https://www.youtube.com/watch?v=S6wEfu61OMM Hillslope angle (a) and elevation (b) of the built up area in Medellín, categorized by utility tax, known as Strata, which determines the socio-economic status of different neighbourhoods. For example, the utility tax decreases as the categories get lower. Hillslope angle increases generally towards poorer categories. Figure from Oztuk et al. (2025), with the caption lightly edited.

Thanks for sharing @davepetley.bsky.social!

@theronfinley.bsky.social, Panya, Jan, and I were very fortunate to be able to get to the site to survey the impacts of the earthquake. I'm very grateful for how many "once in a lifetime" opportunities we get up here!
