Abstract
Aftermath of the Indian Ocean Tsunami of December 26, 2004, which caused approximately 230 000 fatalities, the Ministry of Earth Sciences (MoES) has taken up the responsibility to establish the National Tsunami Early Warning System at Indian National Centre for Ocean Information Services (INCOIS), Hyderabad. The Indian Tsunami Early Warning System (ITEWS) is operational since October, 2007 and comprises of a real-time network of Seismic Stations, Bottom Pressure Recorders (BPR) and Tide gauges to detect Tsunamigenic earthquakes and to monitor tsunamis. A state-of-the-art early warning centre was developed with all the necessary computational and communication infrastructure that enables reception of real-time data from all the sensors, analysis of the data, generation and dissemination of tsunami advisories following a standard operating procedure.
This report describes about the various components of the ITEWS, provides a glimpse of the standard operating procedure followed for dissemination of the advisories, the types of products generated and the action to be taken for different threat status of the advisories.

Abstract
The Intergovernmental Coordination Group for the Indian Ocean Tsunami Warning and Mitigation System (ICG/IOTWS) was formed in response to the tragic tsunami on December 26th 2004, in which over 230,000 lives were lost around the Indian Ocean region. The Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO) assembly, during its twenty-third Session (21-30 June 2005), formally established the ICG/IOTWS through Resolution IOC-XXIII-12, which meets regularly to establish and implement working plans in the Indian Ocean region. The IOTWS comprises a network of National Tsunami Warning Centres (NTWC) in each Member state receiving tsunami advisories from Regional Tsunami Advisory Service Providers (RTSP) that are establishing capabilities to issue regional tsunami bulletins for the Indian Ocean. The IOTWS will therefore operate as a "system-of-systems".
The Indian Tsunami Early Warning Centre operated by the Indian National Centre for Ocean Information Services (INCOIS) has been established with all the necessary capabilities to serve as one of the RTSPs for the Indian Ocean. During the ICG/IOTWS V Meeting at Kuala Lumpur during April, 2008, India presented its proposal for offering RTSP Services for the Indian Ocean. The capabilities of the Indian System against the RTSP Benchmarks were presented and subsequently the Indian National Tsunami Early Warning Centre started exchanging SL-1 Earthquake information with the other RTSPs. India is now fully geared up to provide SL-2 bulletins for the Indian Ocean region as part of the IOTWS.
This document provides details of the Indian RTSP services such as the observing systems, modeling, operating procedures, products, dissemination methods, etc. and is intended to serve as a user guide to the NTWCs.
