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 […]

The shifting pattern of landslide risk in cities – an interesting case study from Medellín
An fascinating case study from the 24 June 2025 Granizal landslide in Medellín, Colombia, which killed 27 people and destroyed 50 homes, shows demonstrates that it is not just the urban poor that are exposed to landslides. That urban areas can be subject to high levels of landslide risk is well-established – commonly cited examples […]
When Should a Tsunami Not Be Called a Tsunami?
It’s time to redefine the term so it more clearly conveys meaningful risks to coastal communities and prompts them to act when needed.
Environmental Hazard Impact Metrics That Matter
Humans acutely experience climate change when they encounter extreme environmental conditions, but scientific definitions of “extreme” often don’t reflect communities’ complex lived experiences.
Busy Hurricane Season Expected in 2025
A new NOAA report predicts an active Atlantic hurricane season, though global weather patterns could still shift predictions.
Cómo pueden los vulcanólogos mejorar la resiliencia urbana al cambio climático
Las estrategias pensadas para ciudades enteras para hacer frente al cambio climático pueden beneficiarse de los conocimientos de los vulcanólogos, que llevan mucho tiempo adaptando la información y la comunicación sobre riesgos a las comunidades locales.
Protecting vulnerable populations from debris flows
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. Channelised debris flows are a major cause of landslide fatalities globally. These are terrifying events, occurring with huge speed and violence, sometimes at night and, of course, usually in poor weather. It […]
Risk-to-life from a coseismic landslide-triggered tsunami in Piopiotahi/Milford Sound, Aotearoa/New Zealand
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 9 December 2019, a small phreatic eruption occurred on Whakaari/White Island in Aotearoa/New Zealand at a time when there were 47 people, most of whom were tourists, on the site. Tragically, […]
Landslide risk in La Paz, Bolivia
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. AFP has posted a very good overview of the hazards posed by landslides in the capital city of Bolivia, La Paz (unfortunately it cannot be embedded). Located at a high elevation, characterised […]
Guidelines for Managing Induced Seismicity Risks
Consolidating state-of-the-art science into guidelines provides a path forward for managing induced seismicity risks and highlights avenues for future research.
