成果の概要／エネスク・ボグダン

My research focused on the Japanese earthquake activity, as well as the earthquake
activity in other Asian countries with intense seismicity. The objective is to bettercharacterize triggered seismicity following large inland and subduction-zone
earthquakes and, in this way, to contribute to a better assessment of earthquake haza rd.
In order to achieve this goal, I initiated two international collaborations, withresearchers from Singapore and Taiwan. I had also an invited seminar in both countries.
During my trip to Singapore (January 16-19, 2019), I have established a fruitfulcollaboration with Prof. Shengji Wei, Earth Observatory of Singap ore (EOS), Nanyang
Technological University. The topics we have discussed include:
1) Work on the seismicity of Myanmar, where EOS has installed a relatively new
broadband seismic network. Due to the active tectonics in the region, Myanmar isthreatened by a high level of seismic hazard. However, the earthquakes and velocity
structure in the region are poorly known due to the lack of regional seismic
observations. This is the target of the current project, in which one of our graduate
Ph.D. students will be involved.
2) Integrate the findings for Myanmar into the broader seismotectonic framework ofAsia and compare seismicity features with those in Japan.
During my trip to Taiwan (March 24-26, 2019), I visited the laboratory of Prof. KateChen, National Taiwan Normal University, following a visit of one of her Masterstudents to our laboratory. The collaboration with Prof. Chen focused on thecharacterization of seismicity of the southern Central Range. We have applied
earthquake detection methods, similar to those employed in Japan, for detecting verysmall earthquakes and correlate thei r occurrence with the fault structu re.
Our current research focuses on earthquake activity in Japan (e.g., the 2018 Osakaearthquake) and other seismic regions in Asia . In order to process various data for Japanor those recorded in other regions (e.g., Myan mar), we need powerful workstations andmemory for data storage. Therefore, in the following weeks (within May), I am planningto purchase with the remaining funds a Dell workstation for heavy computati ons. The
computer will be dedicated to pro cessing earthquake waveform data and advance theresearch I have started recently, in collaboration with our international partners.
I am very grateful to the foundation for their financial support that made possible thisresearch possible and will do my best in the future.
