'Cold lava' floods Philippines village after eruption

I't more like mud than lava. Anyway, it can be very dangerous. My family is from the north west of Arentina (Jujuy). In some areas there is a somewhat similar problem that is not caused by a volcano, just unusual heavy rains that create mud. We even call it "Volcán" (volcano).

There was a big disaster a few years ago [1], but smaller one are usual and they have to rebuild the roads and bridges from time to time.

It seems to me that years ago people would point out a stretch of dead trees killed by a mud flow from Mount Rainier.

This is definitely not “cold lava”, which isn’t a thing. It’s just mud from a lahar flow. When it is fresh and moving, it can be very destructive like a river of concrete.

In other words, a Lahar flow. Pretty common in the Philippines, I've seen a few while on that country.

A lahar was the cause of a deadly railway accident in New Zealand about 60 years ago: https://en.m.wikipedia.org/wiki/Tangiwai_disaster
