How does a guyot form?
A guyot is a volcano built up from the sea floor, sometimes to sea level or above. The sea floor gradually sinks an flattens guyots are submerged to become undersea flat topped peaks. Guyots are chiefly found in the Pacific ocean. Seamounts (Guyots) are formed by volcanic activity and can be taller than 3,000 meters (10,000 ft.) They can be isolated or large parts of mountain chains. The New England Seamount contains more than thirty peaks that stretch 1,600 kilometers (about 994 miles) from the coast of New England.

Seafloor spreading itself does not cause tsunamis. Tsunamis are typically triggered by seismic events, such as underwater earthquakes, volcanic eruptions, or landslides, which can displace large volumes of water and create powerful waves.
Which undersea volcanic has a flat peak?
Guyot
Process that forms new seafloor?
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.
What is the cause of most tsunami's?
