There are two entirely different meaning of waves produced by gravity. In oceanography they're called tides. In astrophysics they're called gravitational waves.

Waves produced by earthquakes are called seismic waves. These waves can be further categorized into primary (P-waves), secondary (S-waves), and surface waves.
The waves produced by earthquakes are called seismic waves.
They're called Seismic waves
These waves are called "Tsunami" Note , Earthquakes CAN cause giant waves (not all sub sea earthquakes do this). Note also that there are other causes of Tsunami.
it's gravity disturbs the oceans. can cause giant waves.
Modulating gravity waves is currently beyond our technological capabilities, as gravity waves are extremely weak and difficult to manipulate. These waves are produced by massive cosmic events such as colliding black holes or neutron stars, and detecting them requires highly advanced equipment like LIGO (Laser Interferometer Gravitational-Wave Observatory).
The waves that we perceive as heat are called infrared waves. These waves have longer wavelengths than visible light, and they are produced by the vibration and movement of atoms and molecules.
Gravity waves have nothing to do with tornadoes.
Giant ocean waves may be the result of constructive interference of smaller waves.
