SUMMARY:Advances in Computational Geosciences, Part IV
DESCRIPTION:Minisymposium\n\nComputational geosciences leverage advanced c
 omputational methods to improve our understanding of the interiors of  Ear
 th and other planets. They combine numerical models to understand the curr
 ent state of physical quantities describing a system, to predict their fut
 ure states, and to infer unknown parameters of those models from data meas
 urements. Such models produce highly nonlinear numerical systems with extr
 emely large numbers of unknowns.\nThe ever-increasing power and availabili
 ty of High Performance Computing (HPC) facilities offers researchers unpre
 cedented opportunities to continually increase both the spatiotemporal res
 olution and the physical complexity of their numerical models. However, th
 is requires complex numerical methods and their implementations that can h
 arness the HPC resources efficiently for problem sizes of billions of degr
 ees of freedom.\nThe goal of this minisymposium is to bring scientists who
  work in theory, numerical methods, algorithms and scientific software eng
 ineering for scalable numerical modelling and inversion. Examples include,
  but are not limited to, geodynamics, multi-phase geophysical flow modelli
 ng, seismic wave propagation and imaging, seismic tomography and inversion
  of large data sets, development of elaborate workflows including HPC for 
 imaging problems, ice-sheet modelling, and urgent computing for natural ha
 zards.\n\nThe Role of HPC in the Search of Next-Generation Earthquake Fore
 casting Models\n\nMizrahi, Nandan, Wiemer\n\nEarthquakes can be large and 
 devastating, and despite decades of research on the topic, they remain vir
 tually unpredictable. However, precautionary measures taken based on knowl
 edge about seismic hazard can help minimizing the risk and save lives. Thi

 ---\nStochastic Modeling for Earthquakes, an Alternative Method for Unders
 tanding the Seismic Process\n\nMonterrubio, Zúñiga, de la Puente, Aguilar-
 Melendez, Carrasco-Jimenez...\n\nIn general terms, earthquakes are the res
 ult of brittle failure within the heterogeneous crust  of the Earth. 
 However, the rupture process of a heterogeneous material is a complex

 Frequency Sensitivity of Waves probing Global Deep Earth Structure using S
 pectral-Element and Adjoint Methods\n\nKoroni\n\nUsing spectral-element an
 d adjoint methods, this study investigates the sensitivity of seismic wave
 s to structural and boundary parameters of the earth. Understanding wave p
 ropagation effects on many body wave seismic phases travelling through the
  earth is important for improving 3-D mantle models. ...\n\n--------------
