No chance of that. Pillaro, Patate, and the towns of Valle Hermoso are reporting 5 cm of ash, just today. The IG (who monitors our volcanos) has noted that the ash content of the emissions has increased by 25% since yesterday. Bilbao and the SW towns are starting to voluntarily evacuate.

The greatest danger from an eruption like this one is from the sheer volume of ash that the volcano puts out, especially if it starts raining. That produces something called lahar, which is basically a gigantic volcanic-ash mudslide. What made the 1998-99 eruption so damaging was that the volcano had a small glacier on the peak, which melted when the heat picked up and created instant cement mudslides. At least this time, that didn't happen because there was no glacier left.
