We would like to inform you that this site, the GSJ Volcanic Hazard Assessment Support System, is temporary moved to https://ccop-geoinfo.org/ , as we are changing the new URL of the system. The system's new URL will be https://volsimulation.org which will be functional on February 25, 2021. We are also updating Titan2D and it is temporarily turned off. The service will be available when the job is completely done.

Please click the button below to go to the temporary site. You will be automatically re-directed when the time lapses below.
