چکیده
Magma decompression rate is one of the most important parameters in controlling eruption dynamics. One way to determine by fitting a volatile elements diffusion profile concentration gradient crystal-hosted embayments. Previous studies have used variety models, limiting possibility for inter-study comparison. Here, we introduce EMBayment-Estimated Rates (EMBER), standalone versatile tool that models along melt Our model relies on pdepe function MATLAB calculate profiles H2O, CO2, and S through finite difference method. EMBER uses grid search seeking out best fits rates, initial dissolved each studied exsolved gas content, while setting three constants: temperature ascent pressure at beginning end ascent. can compute basaltic, intermediate, rhyolitic compositions. We applied previous evaluate validate our model. then reprocessed “homogeneously” raw data from literature In other words, same protocol was removing literature-specific strategies constrain unknown parameters. With this comparison, found statistically significant positive correlation between maximum magma rates explosivity related eruption. expected help increase number embayments aiming constraining facilitate comparisons.

Magma decompression rates during explosive eruptions of Kīlauea volcano, Hawaii, recorded by melt embayments
The decompression rate of magma as it ascends during volcanic eruptions is an important but poorly constrained parameter that controls many of the processes that influence eruptive behavior. In this study, we quantify decompression rates for basaltic magmas using volatile diffusion in olivine-hosted melt tubes (embayments) for three contrasting eruptions of Kīlauea volcano, Hawaii. Incomplete e...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
