This open access volume contains a selection of papers presented at three different IAG Symposia held in 2022: GGHS2022 – Gravity, Geoid, and Height Systems 2022, Austin, TX, United States of America, September 12 – 14, 2022; IAG Commission 4 – Positioning and Applications, Potsdam, Germany, September 5 – 8, 2022; and REFAG2022 – Reference Frames for Applications in Geosciences, Thessaloniki, Greece, October 17 – 20, 2022. Two of these three conferences were planned for 2020 or 2021, but had to be postponed due to the COVID19 pandemic. They therefore became an important opportunity for the global geodesy community to rebuild professional networks and to resume face-to-face interaction. Scientists from around the world were delighted to once again gather together to present their research progress and findings, and discuss scientific issues.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 179.This multidisciplinary monograph provides the first modern integrative summary focused on the most spectacular active tectonic systems in North America.Encompassing seismology, tectonics, geology, and geodesy, it includes papers that summarize the state of knowledge, including background material for those unfamiliar with the region; address global hypotheses using data from Alaska; and test important global hypotheses using data from this region.It is organized around four major themes: subduction and great earthquakes at the Aleutian Arc,the transition from strike slip to accretion and subduction of the Yakutat microplate,the Denali fault and related structures and their role in accommodating permanent deformation of the overriding plate, andregional integration and large-scale models and the use of data from Alaska to address important global questions and hypotheses.The book's publication near the beginning of the National Science Foundation's EarthScope project makes it especially timely because Alaska is perhaps the least understood area within the EarthScope footprint, and interest in the region can be expected to rise with time as more EarthScope data become available.

The theme of the Assembly was Geodesy for a Sustainable Earth. 613 contributions (255 oral presentations and 358 poster presentations) covered all topics of the broad spectrum considered by the IAG: geodetic reference frames, Earth gravity field modelling, Earth rotation and geodynamics, positioning and applications, the Global Geodetic Observing System (GGOS), geodesy for climate research, marine geodesy, and novel sensors and quantum technology for geodesy. All published papers were peer-reviewed, and we warmly recognize the contributions and support of the Associate Editors and Reviewers.

This open access volume contains the proceedings of the X Hotine-Marussi Symposium on Mathematical Geodesy which was held from 13 to 17 June 2022 at the Politecnico di Milano, Milan, Italy. Since 2006 the series of the Hotine-Marussi Symposia has been under the responsibility of the Inter-Commission Committee on Theory (ICCT) within the International Association of Geodesy (IAG). The ICCT organized the last five Hotine-Marussi Symposia held in Wuhan (2006), Rome (2009, 2013 and 2018), and Milan (2022). The overall goal of the ICCT and Hotine-Marussi Symposia has always been to advance geodetic theory which is indeed documented by the 22 research articles published in these proceedings.  The jubilee X Hotine-Marussi Symposium was organized in 10 topical sessions covering all parts of geodetic theory including reference frames, gravity field modelling, adjustment theory, height systems, time series analysis, or advanced numerical methods. In total, 60 participants attended the Symposium who delivered 62 oral and 18 poster presentations. During a special session, five invited speakers discussed two basic concepts of physical geodesy – geoid and quasigeoid.

This open access volume contains a selection of papers presented at three different IAG Symposia held in 2022: GGHS2022 – Gravity, Geoid, and Height Systems 2022, Austin, TX, United States of America, September 12 – 14, 2022; IAG Commission 4 – Positioning and Applications, Potsdam, Germany, September 5 – 8, 2022; and REFAG2022 – Reference Frames for Applications in Geosciences, Thessaloniki, Greece, October 17 – 20, 2022. Two of these three conferences were planned for 2020 or 2021, but had to be postponed due to the COVID19 pandemic. They therefore became an important opportunity for the global geodesy community to rebuild professional networks and to resume face-to-face interaction. Scientists from around the world were delighted to once again gather together to present their research progress and findings, and discuss scientific issues.
