Interagency team coordinated by the SHOP1) of CS2);
1. is monitoring the current status of the 3.11 Tsunami Debris based on the reports from navigating ships and satellite imagery
2. is trying to predict of trajectory by numerical simulation
3. shares the information with other countries which may be affected by the 3.11 Tsunami Debris
