Short summary

The 1 February 2014 eruption of the Tungurahua volcano (Ecuador) was the second largest one since the re-awakening in 1999. The eruption showed precursory signs only 48 h before the eruption. The main explosions produced a 13 km eruptive column and pyroclastic density currents that reached the base of the volcano. Here we document the deposits related to the eruption and infer eruption mechanisms and transport processes.
