Both fixed probability and fixed ash threshold maps are valuable probabilistic volcanic hazard map content types for organisational stakeholder groups.
Strategic planners therefore fixed their attention on the little volcanic island of Iwo Jima in the Bonin Islands, which lay about halfway between the Marianas and Japan.
Ratios between volcanic gas species are estimated using the scatter plot with an assumption of two-component mixing of a volcanic gas and an atmosphere with a fixed composition.
What is more interesting is the likelihood that the deep ocean oligotrophic sediments have retained their chemosynthetic potential: at 1 atm (0.1013 MPa) and at 5°C, the siliceous oozes of CIOB fixed 5 45 nmol C (g dry wt)−1 d−1 and red clay with volcanic signatures fixed 230 9,401 nmol C (g dry wt)−1 d−1 [50].
The linear volcanic trends, such as the Hawaiian, Emperor, and Line island chains in the central and northwestern Pacific, are trails resulting from the movement of the Pacific Plate over volcanic "hot spots" (that is, magma-generating centres) that are probably fixed deep in Earth's mantle.
The instruments were not fixed in boreholes and hence the data are considered unreliable, with non-volcanic causes of tilt (e.g. ground surface instability, wind, heavy rainfall).
We used the estimated evolutionary split of the two undescribed species endemic to the Comoro island of Mayotte (Blommersia sp. 4, Boophis sp. 1) as fixed calibration points, which is estimated at 8.7 ma based on the age of the volcanic island of Mayotte [[ 44]; validated in [ 68]].
While Bayesian methods can be used to examine the uncertainty introduced by parameter calibration (e.g. Kennedy and O'Hagan 2001; Denlinger et al. 2012; Anderson and Segall 2013; Madankan et al. 2014), often inversion of volcanic plume models has varied only a single member of the set of source conditions while leaving others at fixed 'characteristic' values.
The parameters marked 'Well constrained' are held fixed in the parameter sensitivity screening Laboratory experiments and high-resolution computational simulations of the fundamental governing equations can provide insight into the numerical values of the entrainment coefficients, but the values obtained for laboratory-scale plumes may not be appropriate for field-scale volcanic plumes.
"We keep fixing, fixing, fixing".
