At the meeting of the Intergovernmental Coordination Group (ICG) for the Indian Ocean Tsunami Warning and Mitigation System (IOTWMS) Working Group 2 on Tsunami Detection, Warning and Dissemination held in Hyderabad, India, 12-13 November 2015, the Working Group recommended to conduct a pre-IOWave16 Exercise workshop on Standard Operating Procedures (SOPs) for tsunami warning and emergency response in May or June 2016 involving the IOTWMS Tsunami Service Providers (TSPs), National Tsunami Warning Centres (NTWCs) and Disaster Management Offices (DMOs). This recommendation has subsequently been endorsed by the IOTWMS Steering Group. The primary goals of the workshop will be: to assist the ICG/IOTWMS Member States to develop integrated end-to-end SOPs for tsunami warning and emergency response; to assist National/Local DMOs to develop SOPs for implementing national and local responses to tsunami warnings issued by the NTWCs; and to prepare Member States to conduct the IOWave16 Exercise scheduled to be held on 7th and 8th September 2016. The workshop objectives will be to understand how TSP products are used by NTWCs and National/Local DMOs in their SOPs; to identify potential gaps and possible challenges for warning chain SOPs at the national and local levels; and to develop and integrate SOPs between NTWCs, National DMOs and Local DMOs. The workshop will focus on SOPs for tsunami warning and emergency response from national to community level, and IOTWMS Member States intending to participate and include local community response in the IOWave16 Exercise are encouraged to submit nominations
