Exercise Pacific Wave 2020 (PacWave20) intends to support the development of improved PTWS tsunami products and procedures, including the products of the Central America Tsunami Advisory Centre (CATAC) of the Instituto Nicaragüense de Estudios Territoriales (INETER). Accordingly, the aim of PacWave20 is to test PTWS tsunami service provider arrangements, country preparedness arrangements and operational procedures to respond and recover from a destructive tsunami. The original objectives for Exercise Pacific Wave 2020 were fourfold: (a) Test communications from the PTWS Tsunami Service Providers to Tsunami Warning Focal Points and National Tsunami Warning Centres of Member States. (b) Test national communication and cooperation, and readiness within the country. (c) Test regional communication and cooperation between Member States. (d) Support the development of tsunami procedures and products by the Central America Tsunami Advisory Center (CATAC) (Only applicable to relevant countries).
