#1. Preface by Yukihiro Takahashi, President of JpGU

The abstract submission deadline for the 2023 meeting is less than a
week away. In addition to 229 diverse sessions covering all areas of
Earth and planetary sciences, also planning for a variety of events is
underway. More than 10 Union sessions are scheduled on important
topics that cut across the entire spectrum of Earth and planetary
sciences. In addition to large societies such as American Geophysical
Union (AGU) and the European Geosciences Union (EGU), societies
from developing countries will be invited to discuss international
diversity and inclusiveness in U-01 “Inclusion in Earth and Planetary
Sciences,” the International Year of Basic Sciences for Sustainable
Development (IYBSSD) by the United Nations and UNESCO U-09 “Contribution
of Earth and Planetary Science to the International Year of Basic
Sciences for Sustainable Development (IYBSSD)” was organized in
cooperation with the Committee on Earth and Planetary Sciences of the
Science Council of Japan.

On February 6, a major earthquake occurred in Turkey and Syria, and
it was reported that more than 20,000 people were killed, more than
in the Great East Japan Earthquake. I would like to express my deepest
sympathies and condolences to those who lost their lives and those
who were affected by the disaster. In order to overcome such a
large-scale natural disaster, we need to take into account our past
experiences and subsequent efforts. A public session, O-04 “100 Years
after the Great Kanto Earthquake. Can the evolution of society overcome
the next disaster?” will review the progress of society and academia
in the 100 years since the Great Kanto Earthquake in cooperation with
the academic alliance for disaster reduction, which consists of
various academic societies including engineering, science, medicine,
and social sciences. In addition, I feel that JpGU has a major role to
play in international cooperation in the area of disaster prevention.
Also the disaster prevention will be a major point of contact in
relations with developing countries that are seeking to develop basic
science in the future.
As the response to the COVID in each country is changing drastically,
I hope that many people will participate in the meeting and enjoy the
special atmosphere that only a face-to-face meeting can bring. At the
same time, we will strive to make the meeting a fulfilling experience
for those who are concerned about the still unpredictable infection
situation, as well as for those who live overseas or participate
online due to circumstances beyond their control.
We look forward to receiving many abstract submissions.

#5. From Committees

(1) Committee for Diversity Management and Talent Pool

– The Career Explorer (CE) Logo launched
JpGU has created “The Career Explorer Logo (CE Logo)” that allows
members who are currently seeking employment to indicate this in their
presentations. Those who wish to use the logo may place it on their
JpGU Meeting presentation proceedings and in their presentation
materials including posters. The introduction of this logo will support
the development of career paths for a variety of members, including
students, fixed-term researchers, and those wishing to change jobs
or rehire.

* Please apply for use if you wish.
Application period: 24 March – 14 April 2023 * After the presentation
number is determined.

– Childcare Support
Childcare support during JpGU2023 will be provided in the same manner
as last year. Please refer to last year’s guidelines for reference.

[Call for donations for childcare support]
While the JpGU Committee for Diversity Management and Talent Pool
provided support for childcare fees outside of regular/daily
childcare-use at the last year’s JpGU Meeting, we plan to resume our
support in providing an on-site childcare room at the JpGU 2023, as
we did before the COVID-19 pandemic. However, we have the significant
budget shortfall to do so and we need your financial support.
For your donation to be used for a childcare support, please make a
designated donation by filling out the following form.

Form – Designating donation for a specific purpose
(please fill in after payment from the membership page)

(2) Featured Articles
We will introduce the featured articles selected by the editor-in-chief

@ Ayumu Miyakawa et al.
Evolution of the geological structure and mechanical properties due
to the collision of multiple basement topographic highs in a forearc
accretionary wedge: insights from numerical simulations.
A paper proposing a conceptual geological model for the development
process of geological structures and dynamics when multiple basement
elevations such as seamounts, ridges, and horst collide with forearc
accretionary complexes in subduction zones.

@ Tokuta Yokohata et al.
Assessing and projecting surface air temperature conditions required
to sustain permafrost in Japan.
This study assesses the impact of anthropogenic climate change on
permafrost, which is present in Japan, albeit on a small scale. The
conditions under which permafrost is maintained are examined in
detail. The study shows that monitoring the mountain environment is
an effective way of understanding the progress of current warming
and taking countermeasures.
