Geodynamic and natural hazards processes produce among other effects deformation and gravity changes which can be measured, using space and ground-based techniques. It is widely recognized that obtaining high temporal rate and high spatial resolution data over wide areas could enhance our mapping capability of such hazardous processes. However, it is also necessary to develop new mathematical (analytical and/or numerical) models and methods for a correct interpretation and, eventually forecast. This book is dedicated to the description of theoretical models, inversion techniques and their application to observational geodetic and geophysical data sets in active geodynamic areas and affected by natural hazards. This book compiles part of the papers presented at the 15th Annual conference of the International Association for Mathematical Geosciences held in Madrid, Spain during September 2-6, 2013. This conference had the special topic of “Mathematics of the Planet Earth” emphasizing the recent importance of modelling in our understanding of Geoscience problems. In this regard, the session XIII “Deformation modelling, Geodynamics and Natural Hazards” served to discuss modelling and observational works of structural and deformation processes (e.g., geodesy, seismology) relevant to the study of Geodynamics and Natural Hazards.

During the last decades, the monitoring and modelling of various geodynamic processes have gained ever increasing importance. In particular, temporal variations of the deformation and gravity fields recorded by new types of geodetic measuring techniques and reflecting isostatic, tectonic or volcanic processes in the earth's interior as well as climatologically induced changes on its surface have opened new avenues. The present volume succeeds a similar topical volume published in 2007 and reflects the most recent developments in these fields of research. Part of the papers in this book were presented at the second workshop on 'Deformation and Gravity Change: Indicators of Isostasy, Tectonics, Volcanism and Climate Change' that took place at the Casa de los Volcanes on Lanzarote, Spain, during March 27-30, 2007. It was jointly organized and supported by the International Association of Geodesy (IAG), the Spanish Ministry of Education and Science, the Spanish Council for Scientific Research and the Cabildo Insular de Lanzarote. The workshop also served as the second meeting of the members of the IAG Working Group ICCT2 on 'Dynamic Theories of Deformation and Gravity Fields'.

Most of the papers in this book were presented at the workshop on "Deformation and Gravity Change: Indicators of Isostasy, Tectonics, Volcanism and Climate Change", which took place at the Casa de los Volcanes on Lanzarote, during March 1-4, 2005. Leading experts describe major developments in geodynamics, and record their views on internal and surface processes of the earth.

This book presents the outcomes of the workshop sponsored by the National Natural Sciences Foundation of China and the UK Newton Fund, British Council Researcher Links. The Workshop was held in Harbin, China, from 14 to 17 July 2017, and brought together some thirty young (postdoctoral) researchers from China and the UK specializing in geosciences, sensor signal networks and their applications to natural disaster recovery. The Workshop presentations covered the state of the art in the area of disaster recovery and blended wireless sensor systems that act as early warning systems to mitigate the consequences of disasters and function as post-disaster recovery vehicles. This book promotes knowledge transfer and helps readers explore and identify research opportunities by highlighting research outcomes in the internationally relevant area of disaster recovery and mitigation.

The recent understandings about global earth mechanics are widely based on huge amounts of monitoring data accumulated using global networks of precise seismic stations, satellite monitoring of gravity, very large baseline interferometry, and the Global Positioning System. New discoveries in materials sciences of rocks and minerals and of rock deformation with fluid water in the earth also provide essential information. This book presents recent work on natural geometry, spatial and temporal distribution patterns of various cracks sealed by minerals, and time scales of their crack sealing in the plate boundary. Furthermore, the book includes a challenging investigation of stochastic earthquake prediction testing by means of the updated deep machine learning of a convolutional neural network with multi-labeling of large earthquakes and of the generative autoencoder modeling of global correlated seismicity. Their manifestation in this book contributes to the development of human society resilient from natural hazards. Presented here are (1) mechanics of natural crack sealing and fluid flow in the plate boundary regions, (2) large-scale permeable convection of the plate boundary, (3) the rapid process of massive extrusion of plate boundary rocks, (4) synchronous satellite gravity and global correlated seismicity, (5) Gaussian network dynamics of global correlated seismicity, and (6) prediction testing of plate boundary earthquakes by machine learning and generative autoencoders.
