Established in 2005, the Charles F. Richter Early-Career Award is part of SSA’s longstanding commitment to supporting the next generation of seismologists. The award honors outstanding contributions to the goals of the Society by a member early in her or his career and provides recipients with a $3,000 cash award from the William B. Joyner Memorial Fund.

Award Criteria

The Richter Award honors outstanding contributions to the goals of the Society by a member early in their career and is given no more than once a year. An awardee’s contributions should advance
seismology and/or the understanding of earthquakes for the benefit of society and reflect the core values of SSA.

Award Eligibility

Nominees must satisfy the following criteria: 1) they must be regular or honorary members of the Society in good standing and 2) their most recent academic degree must have been awarded no more than six years prior to the year in which the award is given.  For the 2025 Richter Award, all eligible nominees must have completed their most recent academic degree in 2019 or later.*

* Family or medical leave, if provided by the candidate’s institution and taken by the nominee during this six-year period, can extend the six-year period.

No individual who is a member, member-elect or officer of the Board of Directors at the time of the nomination deadline shall be eligible for nomination.

Nomination Procedure

The chief nominator must be an SSA member who is eligible to submit a nomination. Any member of SSA may nominate a candidate for this award, with the exception of members of the Richter subcommittee, SSA Board of Directors and SSA Award Encouragement Committee.

The nomination package should contain: 1) a letter of nomination no more than two pages long that establishes the nominee’s eligibility and summarizes the nominee’s significant accomplishments, 2) a curriculum vitae including bibliography, 3) two to four supporting letters no more than two pages long, including at least two letters from individuals who are not currently employed at the nominee’s current institution nor the institution from which the nominee received their most recent degree. Any unsuccessful nomination may be considered again in the following year’s award cycle without resubmission of the nomination package if the nominee still meets eligibility requirements and their reconsideration is requested by a nominator before 30 September of that year. To be reconsidered in subsequent years (beyond the year immediately following the original nomination), a new nomination package must be submitted. The Executive Director will contact nominators via email prior to 30 September to confirm willingness for reconsideration of a package for a second year.

A signed nominator disclosure form submitted by the chief nominator must be included with every submission. Click here to complete the Ethics Disclosure Form for Nominators.

Awardee Selection

The Richter Subcommittee will seek one qualified recipient for the award to recommend to the Board. If the subcommittee feels there is no qualified recipient, they will recommend that no award be conferred that year. If the subcommittee cannot decide between two

nominees, the subcommittee may forward two names to the Board for vote. After making its selection, the Subcommittee should write a letter to the Board containing: 1) a list of all nominees, 2) the proposed recipient, 3) some text briefly explaining the nominee’s characteristics that justify the subcommittee’s decision 4) optionally, if deemed necessary, some text listing in general terms, without naming names, the reason the proposed recipient was preferable to the other candidates and 5) a brief description of the selection process. The subcommittee will provide this letter to the HC Chair who will forward the letter and nomination package for the proposed recipient to the Executive Director. The Board will vote up or down on the proposed recipient.

The HC does not review the Subcommittee decisions, except in the case that two nominations are forwarded for vote. The HC may review the procedures and/or act in an advisory capacity to the Subcommittee. The HC, the SSA Board and staff should keep names of nominees and nomination materials private.

Subcommittee Membership

Six persons, including the chair, serve on this subcommittee. All subcommittee members must be SSA members. One member of the subcommittee, preferably the chair, should also be a member of the HC. Subcommittee membership may include no more than two past Richter Award recipients and would ideally include a mix of mid to late career members. No person eligible for the Richter Award may sit on the subcommittee. Normal term of service is two years, with the chair serving for two years.

Deadline and More Details

Nominations for all SSA awards should be sent to the SSA Secretary by 30 September. Electronic submissions should be e-mailed in .TXT, .PDF or .DOC files to

2024 Charles F. Richter Early-Career Award

Doyeon Kim

Doyeon Kim (DK), a lecturer in planetary science in the Faculty of Engineering at Imperial College London has been honored with the 2024 Charles F. Richter Early Career Award for his scientific productivity across a variety of topics, including recent work on Martian seismology and his pioneering approaches to seismic imaging.

“I am sincerely grateful for this award, which I humbly attribute to the collective efforts of those who have played a pivotal role in shaping my academic career. This recognition fuels my dedication to furthering the science of seismology on and off Earth, and my desire to pay it forward by mentoring students and the next generation of seismologists,” Kim said.

Kim’s innovative research in seismic imaging and in finding novel ways to process seismic wave data collected from microearthquakes, earthquake coda, meteorite impacts, and oil industry active source experiments, among other sources, have greatly influenced Earth and Martian seismology. His research illuminates subsurface structures ranging from aquifer levels, shallow magmatic systems beneath volcanoes, subducting slabs such as those encountered beneath Alaska, and pervasive scatterers in the core-mantle boundary region, such as the ultra-low velocity zone beneath Marquesas that he and his colleagues discovered and described in a paper published in Science in 2020.

In their commendations of Kim, several colleagues noted that he has been developing a suite of joint inversion toolkits that will be useful to address geophysical datasets collected by future lunar and Martian missions. They also noted that Kim has worked skillfully with large teams of collaborators, a valuable trait in an early career seismologist.
