    In 2012 there was a lot of catching up going on for Colombia’s volcanism.

    Ruiz and Huila turned out to be mega reports due to interesting activity but also large time-spans to report on. I chose some natural breaks in their activity and wrote them as 2-part reports – this strategy might be necessary for Guate’s volcamism; our coverage on Pacaya and Fuego has been intermittent and we’ll hopefully get caught up in 2013. Pue, vamo a ver!
