### Step 1: Placement of Pressure Sensors.

The first step in how tsunami detectors work is the placement of pressure sensors on the ocean floor. These sensors are strategically placed in key locations, such as along fault lines or near tectonic plate boundaries, to detect changes in water pressure caused by seismic activity.

### Step 2: Monitoring Water Pressure.

Once the pressure sensors are in place, they continuously monitor water pressure readings. When there is a sudden drop or rise in water pressure, it can indicate the occurrence of an underwater earthquake or movement of tectonic plates.

### Step 3: Transmitting Data.

When the pressure sensors detect a significant change in water pressure, they transmit this data to a centralized monitoring station via underwater cables or satellite communication. This allows experts to analyze the information in real-time and determine if there is a potential tsunami threat.

### Step 4: Analyzing Data.

At the monitoring station, experts analyze the data from the pressure sensors to determine the size, location, and potential impact of the tsunami. They use computer models and historical data to predict the tsunami's arrival time and estimated wave height.

### Step 5: Issuing Warnings.

Once a potential tsunami threat is identified, authorities can issue warnings to coastal communities in the at-risk areas. This gives residents time to evacuate to higher ground and take necessary precautions to protect themselves and their property.

### Step 6: Monitoring Tsunami Progression.

As the tsunami approaches the coastline, additional monitoring stations along the shore track the progression of the waves in real-time. This information is used to provide updates on the tsunami's size and impact to emergency responders and the public.

### Conclusion.

In conclusion, tsunami detectors work by monitoring water pressure changes on the ocean floor, transmitting this data to monitoring stations, analyzing the information to identify potential tsunami threats, and issuing warnings to at-risk communities. This step-by-step process helps authorities to take timely action and protect lives and property in the event of a tsunami.
