More details on the deadly Huila eruption

nn

I’ve found a few more details about the ongoing activity at Huila in Colombia, including a video report from the BBC. It seems that the eruption at Huila is a photocopy of what happened at Nevado del Ruiz in 1985 in its style: hot ash and gasses erupted from the crater melted ice/snow near the summit to create a lahar – a deadly mix of volcanic material and water that ends up like a surging flow of liquid concrete. The lahars travelled down the Rio Paez valley (see linked map – the landslide on the map is not volcanically related).

Beyond the unfortunate victims caught in the mudflows, many roads and bridges have been damaged in the area near┬áBelacazar. However, the BBC video does mention that many people were, luckily, given sufficient warning to escape the lahars – about an hour according to the man in the video – and resident went uphill to escape the flows. The death toll might be much lower than it could have been, a testament to how far Colombia’s volcano mitigation has come since the 1985 disaster.
