The water receeds (draws back) into the ocean.
Primary Succession
The first sign of a tsunami is often a strong earthquake or underwater volcanic eruption. If you feel strong shaking that lasts for an extended period, see water receding quickly from the shoreline, or hear a loud roaring sound from the ocean, these could be early warning signs of a tsunami. Pay attention to official warnings and evacuate to higher ground immediately if advised to do so.
No. At the the time there was no tsunami warning center in the Indian Ocean. They received no warning. The first indication anyone in Indonesia got was the ocean receding before the tsunami struck, but most people did not know that this was a sign of a tsunami.
The Japanese tsunami of 2011 had just one primary wave, which caused widespread devastation along the coast of Japan.
The first sign is a rapid drop in the sea level.

A tsunami detection buoy is one of the primary instruments used to detect tsunamis. These buoys are equipped with sensors that can detect changes in water pressure caused by a tsunami wave passing overhead. The data collected by these buoys is then transmitted to monitoring stations to provide early warnings.
An earthquake happens in or very near the ocean. And fortunately, other signs are incredibly rare.
A tsunami can travel great distances and strike thousands of miles from where it originated. For example, Hawaii has been hit hard by tsunamis that were tirggered by earthquakes in Alaska and Chile.
The Indian Tsunami Early Warning Centre (ITEWC) is located in Hyderabad, India. It is operated by the Indian National Centre for Ocean Information Services (INCOIS) and serves as the primary agency responsible for detecting and issuing tsunami warnings for the Indian Ocean region.
