First recorded eruption of Nabro volcano, Eritrea, 2011

We present a synthesis of diverse observations of the first recorded eruption of Nabro volcano, Eritrea, which began on 12 June 2011. While no monitoring of the volcano was in effect at the time, it has been possible to reconstruct the nature and evolution of the eruption through analysis of re- gional seismological and infrasound data and satellite remote sensing data, supplemented by petrological analysis of erupted products and brief field surveys. The event is notable for the comparative rarity of recorded historical eruptions in the region and of caldera systems in general, for the prodi- gious quantity of SO2 emitted into the atmosphere and the significant human impacts that ensued notwithstanding the low population density of the Afar region. It is also relevant in understanding the broader magmatic and tectonic signifi- cance of the volcanic massif of which Nabro forms a part and which strikes obliquely to the principal rifting directions in the Red Sea and northern Afar. The whole-rock compositions of Editorial responsibility: G. Giordano the erupted lavas and tephra range from trachybasaltic to trachybasaltic andesite, and crystal-hosted melt inclusions contain up to 3,000 ppm of sulphur by weight. The eruption was preceded by significant seismicity, detected by regional networks of sensors and accompanied by sustained tremor. Substantial infrasound was recorded at distances of hundreds to thousands of kilometres from the vent, beginning at the onset of the eruption and continuing for weeks. Analysis of ground deformation suggests the eruption was fed by a shal- low, NW–SE-trending dike, which is consistent with field and satellite observations of vent distributions. Despite lack of prior planning and preparedness for volcanic events in the country, rapid coordination of the emergency response miti- gated the human costs of the eruption

GCSS Analytics Proof of Concept

Our previous research (TRWG 13-01-016) demonstrated the feasibility and usefulness of ADF (Application Development Framework) to develop a suite of supply analytics to augment GCSS- MC. ADF allows developers to quickly develop data driven web based analytics. This study took the next step by installing the “Analtyics Suite (AS) on NPS virtual servers (using VMware Horizon View). The servers were installed in the .edu domain at NPS. Proper IA procedures were applied to the VMware physical machines. AS (csviewtb.nps.edu) have been made available to selected Marine personnel for evaluation. The goal of this research is to bring this proof of concept as close to a model of a production server as possible. Evaluation of the performance was studied as well. In addition to the above, the research looked at how the GCSS data can be "cleaned up" and an evaluation of the technology needed to deal with dirty or missing data.Naval Research ProgramPrepared for: Topic Sponsor: N2/N6; Research POC: Maj Nic Martinez (LX, DC I&L)NPS-N16-M445-
