Can submarine sonar detect tsunami

Submarine sonar is not typically used to detect tsunamis directly, as tsunamis are large ocean waves that travel across the surface rather than through the water column. However, sonar can be used to monitor changes in underwater topography, seismic activity, and oceanographic conditions that may indicate a tsunami's potential formation. Additionally, some advanced sonar systems can help track the waves once they are formed, but real-time tsunami detection is generally done using a network of buoys and surface wave monitoring systems.
