Geologists have developed instruments to measure changes in elevation in tilting of the land surface and ground movements along fault
Scientist know this by the color difference on the planets surface.
Most surface waves are caused by wind systems. Earthquakes cause tsunamis.
When earthquakes occur, scientists measure them using seismographs. Earthquakes produce a number of different types of waves. Some run along the surface of the earth. Some travel through the earth. Those that travel through the earth travel at different speeds. It is possible to create similar waves in a lab and measure how those waves travel through different types of materials. Since earthquakes occur all over the world, it is possible to measure the waves from all angles. Thus, if a wave travels a small distance through the core, scientists can tell by differences in speed what it would be if it traveled through all mantle material. So with the difference in speeds in different types of waves, scientists can figure out what is in the earth's interior.

Try a tape measure and a calculator to measure surface area.
seismograph
an instrument used to measure the flux of solar radiation through a surface.
The measure of the force with which air molecules push on a surface is air pressure. An instrument that is used to measure air pressure is a barometer.

It is Taylsurf and not as spelt in the question. It is an instrument used to measure surface finish or texture in mechanical engineering.
An albedometer is an instrument used to measure the albedo - the fraction of incident light or radiation reflected by a body - of a surface.
earthquakes are movements on the earths surface
Mo, they are known as earthquakes but the earthquakes cause the tsunamis.
Shake it
An earthquakes epicenter is the point on the surface directly above the focus
