[U13-04] 10 years after the 2011 Tohoku earthquake: A milestone of solid earth science
★Invited Papers
The planning of this special issue began when the editorial board invited the conveners of the JpGU 2021 special session "Ten years from the 2011 Tohoku Earthquake: A milestone of Solid Earth Science". The scope of the session was: “how far has our understanding of these research themes progressed? … the research results in various solid-earth science fields that have clarified after this earthquake and tsunami will be brought together, to discuss the direction of research that should be aimed at in the future”. Therefore, the special issue was a great opportunity to discuss the future direction of research.
A session on "Tsunami deposit: research progress after the 2011 Tohoku-oki earthquake and prospects” was also planned at the same meeting. The scope of this session was "As it commemorates the 10th anniversary of the 2011 off the Pacific coast of Tohoku Earthquake, we would like to review research progress over the past decade and share in the vision of future research”. The two sessions shared the same awareness of the issues, and information was exchanged among the conveners from the time the program was organized. Therefore, we decided to jointly accept the invitation to plan the special issue.
In " Ten years from the 2011 Tohoku Earthquake”, three topics were selected from the viewpoints of the challenges posed to solid earth science by the 2011 Tohoku earthquake and the significant progress made in the following ten years: "Cycle of supergiant earthquakes", "Sub-seafloor structural heterogeneity and slip behavior on the megathrust", and "Slow earthquake activity along the Japan Trench”. The conveners wanted to request review papers from these invited speakers. In this respect, we were very grateful that the PEPS journal accepts the submission of review papers.
In addition to the review papers on the above three topics and regular articles related to the same topics, we received a review paper on the modeling of trans-oceanic tsunamis. This is also an important paper in this special issue, as it focuses on an issue highlighted by the high-quality tsunami waveform records broadly acquired around the Pacific Ocean.
The Tohoku-Oki earthquake has accelerated the research on the recurrence history of infrequent but extraordinarily large earthquakes based on the traces left in the topography and geology. These results were contributed by the participants of the session "Tsunami deposit”. Paleoseismic approaches have been developed not only for coastal areas but also for deep seafloor, and such contributions are also included in the special issue.
In the study of the Tohoku-Oki earthquake, data obtained from seafloor observations in the vicinity of the rupture area made an important contribution. Many results from seafloor observations are included in this special issue. The importance of seafloor observations has been reaffirmed, as a new picture of the Tohoku earthquake can still be obtained from new analyses based on new ideas, even after more than 10 years have passed since the occurrence of the earthquake. In terms of analysis based on new ideas, the proposal of a new method for analyzing fault-slip distribution using GNSS observation data is also interesting.

At every JpGU meeting, special sessions are organized to cover topics of great interest and scientific importance. On the other hand, as the meetings have become larger and larger, it seems that it is no longer rare to miss the talks and posters in the special sessions. Involvement in this project has made us realize that it is very meaningful to have a special issue of the PEPS journal that focuses on important research topics, and that the JpGU special session is a candidate for such a theme.
