Our company's initiatives in Morocco.

  • COMPANY

Our company's initiatives have been featured on the Japan Disaster Prevention Platform's website. The focus of this introduction is on our efforts in Morocco. Since 2020, our company has been responding to Morocco's consideration of earthquake measures, as indicated by UNESCO. We received reference materials and advice from Professor Hiroo Kanamori, an emeritus professor at the California Institute of Technology, and we gained an understanding of the situation in Morocco through reports from JICA and others. In January 2021, we visited the CNRST headquarters in Rabat, the capital of Morocco, where we held meetings and conducted the installation of EQ Guard and evacuation drills. We have released observational data from the earthquake that occurred on September 9.
