Continued inflation of the volcanic edifice since the 1986 to 1987 eruptions (Onizawa et al. 2013) and detection of volcanic CO2 gas in soil (Watanabe 2013) suggest that the magma accumulation rate beneath the Izu-Oshima volcano has recently accelerated as has the potential for eruptions in the near future.
The 2011 Tohoku earthquake induced dilation of the magma reservoir, but the small amount (< 1 μ strain) would limit the potential for triggering eruption (Walter and Amelung 2007).
Incoherence, caused by the emplacement of fresh explosive deposits including pyroclastic flows and ash fall, also has potential for tracking eruption progress, especially in conjunction with SAR amplitude measurements.
One should be wary of the potential for large eruptions when crater temperature decreases.
The potential for hydrothermal eruptions, which could be triggered by reducing hydrostatic pressures, was tested by stepwise dewatering of two, max.
As this deformation occurred in a volcanic dome that does not show remarkable active volcanic phenomena, continuous monitoring of the Atosanupuri volcanic complex is essential for assessing the potential for future eruptions.
We now illustrate some of the ways the BBN formulation can be used in situations of suspected volcanic unrest to evaluate multiple strands of observational evidence and data with the purpose of inferring relative probabilities for different potential eruption scenarios or, indeed, for an outcome of no eruption.
The deadly springs of Gaet'ale deepen the fascination of this region, and their potential for dangerous CO2 gas eruptions would add a touch of irresistible attraction for the particular breed of adventure tourists who are drawnto such areas.
Earth scientists had been warning about potential eruptions for months beforehand, but the information never reached the authorities.
