Brittle‐Ductile Deformation and Tensile Rupture of Dome Lava During Inflation at Santiaguito, Guatemala [PDF]
Journal of Geophysical Research: Solid Earth, 2019 AbstractGas‐and‐ash explosions at the Santiaguito dome complex, Guatemala, commonly occur through arcuate fractures, following a 5‐ to 6‐min period of inflation observed in long‐period seismic signals. Observation of active faults across the dome suggests a strong shear component, but as fault propagation generally proceeds through the coalescence of ...

Mixed Initial-Boundary Value Problem for the Capillary Wave Equation
Advances in Mathematical Physics, 2016 We study the mixed initial-boundary value problem for the capillary wave equation: iut+u2u=∂x3/2u, t>0, x>0; u(x,0)=u0(x), x>0; u(0,t)+βux(0,t)=h(t), t>0, where ∂x3/2u=(1/2π)∫0∞signx-y/x-yuyy(y) dy.

High-Speed Transmission in Long-Haul Electrical Systems
International Journal of Differential Equations, 2018 We study the equations governing the high-speed transmission in long-haul electrical systems i∂tu-1/3∂x3u=iλ∂xu2u, t,x∈R+×R, u0,x=u0x, x∈R, where λ∈R, ∂xα=F-1ξαF, and F is the Fourier transformation. Our purpose in this paper is to obtain the large time

UAS-based tracking of the Santiaguito Lava Dome, Guatemala. [PDF]
Sci Rep, 2020 AbstractImaging growing lava domes has remained a great challenge in volcanology due to their inaccessibility and the severe hazard of collapse or explosion. Changes in surface movement, temperature, or lava viscosity are considered crucial data for hazard assessments at active lava domes and thus valuable study targets. Here, we present results from a

Textural Insights Into the Evolving Lava Dome Cycles at Santiaguito Lava Dome, Guatemala [PDF]
Frontiers in Earth Science, 2018 The structures and textures preserved in lava domes reflect underlying magmatic and eruptive processes, and may provide evidence of how eruptions initiate and evolve. This study explores the remarkable cycles in lava extrusion style produced between 1922

Volume changes at Santiaguito volcano between 2011 and 2019 based on TanDEM-X InSAR data
Frontiers in Earth ScienceThe Santiaguito volcanic dome complex in Guatemala consists of four volcanic domes formed within the 1902 eruption crater of Santa María volcano, with only the oldest dome, Caliente, currently active.

Earth and Space Science, Volume 10, Issue 5, May 2023., 2023 Abstract The Surface Biology and Geology (SBG) mission is part of the National Aeronautics and Space Administration's planned Earth System Observatory. The mid/thermal infrared (MIR/TIR) portion of SBG will deliver high spatial and temporal resolution data designed (in part) to answer fundamental volcano science questions, as outlined in the 2018 ...

Wind Speed as a Dominant Source of Periodicities in Reported Emission Rates of Volcanic SO2
Journal of Geophysical Research: Solid Earth, Volume 127, Issue 12, December 2022., 2022 Abstract Volcanoes have been found to display periodicities or cyclic trends in a wide range of phenomena. These include the eruptive activity itself, but also in the time series of geophysical and geochemical monitoring data such as volcanic degassing.

Asymptotics of solutions to periodic problem for the Korteweg–de Vries–Burgers equation
Studies in Applied Mathematics, Volume 149, Issue 2, Page 523-536, August 2022., 2022 Abstract We consider the periodic problem for the Korteweg–de Vries–Burgers (KdVB) equation with pumping vt−vxx+α3vxxx=v+∂xv2,x∈Ω,t>0,v(0,x)=v0x,x∈Ω,\begin{equation*} {\left\lbrace \def\eqcellsep{&}\begin{array}{c}v_{t}-v_{xx}+\frac{\alpha }{3}v_{xxx}=v+\partial _{x}{\left(v^{2}\right)} ,\text{ }x\in \Omega ,t>0,\\ v(0,x)=v_{0}{\left(x\right)} ,\text{ }
