The Earth, Planets and Space (EPS) Young Researcher Award

(formerly called the EPS Award)

This award shall be known as the “EPS Young Researcher Award.” In general, one researcher shall be awarded annually. The editor-in-chief and the presidents of the following five supporting societies shall award the wining researcher:

  • The Society of Geomagnetism and Earth, Planetary and Space Sciences
  • The Seismological Society of Japan
  • The Volcanological Society of Japan
  • The Geodetic Society of Japan
  • The Japanese Society for Planetary Sciences

The winning researcher must be below 36 years of age at the time of submission of the paper, which must have been published in EPS over the last two calendar years. The “EPS Young Researcher Award Committee,” which is composed of the members of the EPS editorial board, shall nominate the award.

2017

The 2017 EPS Young Researcher Award is granted to Hisashi Hayakawa.

Records of sunspot and aurora during CE 960–1279 in the Chinese chronicle of the Sòng dynasty
Hisashi Hayakawa, Harufumi Tamazawa, Akito Davis Kawamura and Hiroaki Isobe

In this study, records of solar and auroral activities from the 10th to 13th centuries were retrieved from the Chinese chronicle of the Sòng dynasty. The accuracy of these records were tested scientifically through comparison with the 14C contents in tree rings during that period. This is important because it is the first step taken to survey and compile records of sunspots and auroras from historical documents of various regions and in different languages (the authors have also published a paper on historical auroral events using records in the Babylonian astronomical diaries in 2016 EPS), with the ultimate goal of creating an online database for use by scientists studying historical/extreme solar/auroral events and long-term changes in solar/auroral activity. Such a unified dataset with records from various locations and in different languages is the first of its kind, and will therefore be of value to the scientific community.

2016

The 2016 EPS Young Researcher Award is granted to Michiyo Sawai.

Frictional properties of incoming pelagic sediments at the Japan Trench: implications for large slip at a shallow plate boundary during the 2011 Tohoku earthquake
Michiyo Sawai, Takehiro Hirose, Jun Kameda

The slip at the shallow part of the megathrust triggered the destructive Tsunami associated with the Tohoku Earthquake in 2011. Thus, it is important to understand how such a large rupture can take place in sedimentary sequences. Sawai et al. (2014) investigated the dynamic frictional properties of incoming sediment off the Japan Trench. From the experiment with a wide range of coseismic velocities, they found that the friction coefficient is less than 0.2 for a wide range of slip velocities in a smectite-rich zone at the bottom of the sedimentary section, which is equivalent to the fault zone of the Tohoku earthquake. Most importantly, this study showed that the fracture energy of aggregated sediments was by far lower than the ones obtained by the previous experiments using disaggregated sediments. This is an important finding for the generation of shallow rapture. The first author contributed significantly to this excellent study that will be leading a research in a new direction by combining seismological and geological sciences. Thus, Dr. Michiyo Sawai is deserving of the EPS Young Researcher Award 2016.

2015

The 2015 EPS Award is granted to Christoph Püthe.

Determination of the 3-D distribution of electrical conductivity in Earth's mantle from Swarm satellite data: Frequency domain approach based on inversion of induced coefficients
Christoph Püthe and Alexey Kuvshinov

Most previous global induction studies have assumed simple structures of the source field and simplified models of the Earth, using mostly ground-based observations as data. This study presented a new approach to global induction studies using the data from Swarm geomagnetic satellite missions in order to infer the three-dimensional (3-D) conductivity structure of the mantle. The author suggested a consistent way of working with satellite geomagnetic data, the sources of the complex spatial structures, and full 3-D conductivity models. The author not only introduced the concept, but also developed and thoroughly tested a new modeling code to cope with the aforementioned challenges. This study has opened a door to new global induction studies. The first author, Dr. Christoph Püthe, made the most significant contribution to this study. Therefore, we award him the 2015 EPS Award.
