The Old Fort landslide in British Columbia is an 8 millon cubic metre earthflow that has caused the evacuation of the village of Old Fort

Problems continue at the Hidroituango dam site in Colombia. Last week a significant seismic event was recorded in the power house cavern, which is thought to have been generated by a further rockfall in the underground excavation.

A new evacuation of workers has been ordered at the Hidroituango dam site in Colombia in light of a potential landslide of up to 200,000 cubic metres in the next few days. The integrity of the dam is not considered to be threatened.

Yesterday the operators of the dam at Hidroituango announced that the crest of the structure has reached 415 m. This is a substantial step towards increasing the safety of the site

Yesterday a small landslide at the Hidroituango dam site led to the evacuation of some of the workers on the site. Operations continue to manage the situation whilst waiting for the end of the rainy season, and an expected fall in the river level

News reports from Colombia say that an American technical report (possibly by USACE) suggests that landslides of up to 40 million cubic metres are possible at Hidroituango. As the report is not publicly available it is hard to know how to interpret these reports

Reports in the last few hours suggest that the landslide at the Hidroituango dam site has accelerated, and has now exceeded the 10 mm per hour warning threshold. Meanwhile, three scenarios for failure of the dam have been described by the international advisors.

In the last 24 hours there have been further developments at the Hidroituango dam site in Colombia. Monitoring suggests that movements of the slope continue, whilst concerns are being raised about low volume seepage from the dam

In Colombia the Hidroituango crisis has deepened as new landslides have started to form close to the dam site, as shown by tension cracks in the slopes and cracks in the tunnels. The level of risk has risen, and 25,000 people are now displaced

The Hidroituango crisis in Colombia: a number of communities have now been evacuated, whilst operations to raise the crest of the dam continue. At the moment the situation appears to be mostly under control
