The Merapi 2010 eruption provided a rare opportunity to collect empirical eruption impact data. A multi-disciplinary MIA-VITA WP4 mission was carried out in collaboration with BPPTK in the immediate post-eruption phase (28 November - 12 December) to investigate the nature and extent of the volcanic phenomena and associated impacts on buildings, humans and the environment. We report on findings from the first week of our mission (28 November - 6 December), in which we concentrated our studies on the village of Bronggang, approximately 13.5km to the south of Merapi and affected by a dilute, low temperature and pressure surge that detached from the distal edge of a channelized PDC. Following the reduction in alert level and the extent of exclusion zones at Merapi on 3 December, it became possible for the team to enter more proximal affected areas, although appropriate safety measures were taken. In the second week of the mission, we carried out detailed structural and geological studies in Umbulharjo, approximately 6km from the vent and affected by a directed high-pressure surge, and also expanded investigations into impacts on agriculture and human health. The field mission was extended for three days to enable these surveys to be completed. As in the first update report for MIA-VITA partners we have outlined our findings and any preliminary interpretations for i) building and infrastructure impacts, ii) agricultural impacts, iii) health and community, and iv) characteristics of eruptive deposits.
