Pushing the Boundaries of Earthquake Research

An earthquake is a rupture phenomenon occurring deep underground.

Its reality is captured with high precision worldwide as seismic waves generated by fault displacement. Even a moderate magnitude 6 earthquake produces waves that are clearly recorded on the opposite side of the planet.

We do not start our research by asking if a phenomenon can be explained within existing frameworks. Instead, we use what the observation data is telling us as our starting point. Seismic waves contain essential information not only about underground structures but also about exactly what happened at the source.

As major earthquakes occur, research institutions around the world now analyze and publish source models using seismic waves. However, routine analytical methods and source models often fail to sufficiently explain the observation data.

We believe that if the data cannot be explained, we should question the methods and models themselves.

"If the underground structure is unknown, develop an analytical theory that accounts for that uncertainty."
"If the fault geometry is unknown, create a flexible source model that can estimate the shape itself."

By developing such analytical methods, the diversity of earthquake phenomena that was previously overlooked is gradually being revealed. Furthermore, if the observation data indicates that classical earthquake cycle models do not hold true, we communicate those findings to society.

We enjoy the moments when "common sense" is challenged. Rather than following trending research topics, we aim to create "new points" that shift the paradigm of the era.
