VOLCANO: Invitation Cities on Volcanoes 10 – Session 1.12 Understanding Volcanic Processes through Drilling (texto original em Inglês) - Notícia OVGA 09-03-2018
We invite you to submit an abstract to the following session at the Cities on Volcanoes 10 Conference, to be held in Naples, Italy, September 2-7, 2018:
S1.12 | Understanding Volcanic Processes through Drilling
Although in the past most drilling into volcanoes was for geothermal energy, drilling should play an increasing role in volcanology as well. Stratigraphic holes, such as at Campi Flegrei, Italy; Unzen Volcano, Japan; and Mauna Kea, Hawaii, USA provide rich additions to the intrusion and eruption record deduced from surface observations. A directionally drilled borehole at Unzen revealed the compound structure of the conduit and rapid cooling following a lengthy eruption. Penetration of magma bodies by drilling in Hawaii, Kenya, and Iceland, returning fragments of magma quenched in situ, open the prospect of an entirely new level of understanding of how magma behaves and eruptions work. This new era of volcanology is made possible by advances in drilling and sensor technologies. For the future, it is not unreasonable to think that magma under high-threat volcanoes will have pressure, temperature, and chemistry monitored directly from sensors in their magma chambers. In addition, extraction of energy from magma at typical geothermal plant rates could substantially reduce the volume of eruptible magma and therefore eruption risk on a decadal timescale. Given the human lives at stake and the uncertainties of our science, the case to push ahead into this new frontier is compelling.
We invite contributions on results from and aspirations for volcano drilling. These may include geophysical approaches to imaging magma, 3-D views of volcanic systems developed from geophysics and drilling, understanding coupling between hydrothermal and magmatic systems, and borehole instrumentation and experiments.
