Evan’s paper has been accepted for publication by JGR, Solid Earth. His paper addresses a fundamental question in submarine seismic imaging using high-frequency body waves. This is often referred to as “reverberation,” waves that “echo” or “sing” again and again.

Drs. Olugboji (PI) & Baowei Liu (Comp. Scientist) win NSF ACCESS award to construct new maps of Africa’s subsurface using high-performance computing and machine learning. New constraints will help understand Africa’s lithospheric structure, seismicity, tectonics, and interior dynamics.

Our latest research paper, titled “A Short-Period Surface-Wave Dispersion Dataset for Model Assessment of Africa’s Crust: ADAMA”, co-authored by Dr. Tolulope Olugboji and Siyu Xue, an undergraduate research assistant, has just been published in Seismological Research Letters. doi: 10.1785/0220210355

Dr. Tolulope Olugboji gave a virtual talk at McGill University on Oct 22, 2021, titled “The Structure of Oceanic Plates using Machine Learning on Seafloor Vibrations Event”. In this talk, Dr. O described a technique for silencing the singing of

Big congratulations to our new Ph.D. student Jean-Joel who just won the data set grant from UR library to help with studying seismically in Western Africa. Stay tuned for his scientific progress and publications!

Big congrats to co-author Yingping Lu (research master’s in data science, class of 2020) on our paper on seismicity in Western Africa.  We explore a wide array of geophysical datasets collaborating with experts in structural geology, aeromagnetics (Dr. Kolawole &
