Science and Technology for Low-Frequency Risk Evaluation (LFRE) - This research field focuses on infrequent disaster risks, which has quite long recurrence intervals but results in catastrophes to humans and societies, like the 2011 Great East Japan Earthquake.

The importance and motivation for effective utilization of geologic records of past disasters, such as ancient tsunami deposits, are now greatly increased. The LFRE dedicates the interpretation and evaluation of the geologic records of low-frequency risks such as large-scale earthquakes, tsunamis and volcanic eruptions, to contribute for the mitigation and prevention of the enormous disasters. Researches in this field are based on close interdisciplinary and international cooperation of earth sciences and other scientific fields, such as coastal engineering and historical science.
