Hi Ben, thank you for catching this. The correct form is "Technological Disaster", and we will roll out a fix to address this. We'll also take the opportunity to review all other terms.
ReliefWeb uses
GLIDE to identify disasters, and in the next update we'll be adding support for GLIDE hazard codes, like AC for technological disasters.
Thanks again for catching this, and taking the time to let us know. Please look forward to the next update.
Best regards,
Shuichi
