Distance between the peakes and troughs in a waves oscillations.

The height of a wave is also known as its amplitude. More generally, the amplitude is "how much some measurement changes" - this measurement need not always be a height.
You don't. Hz (always capitalized) is the unit for measuring frequency or pitch. dB is the unit for measuring amplitude or relative loudness of the sound. You cannot convert a frequency measurement to an amplitude measurement.

measurement of the amplitude of the largest seismic waves
The vertical distance between a wave's midpoint and its crest or trough is called is peak amplitude. This differentiates this measurement from the vertical distance from a crest to a trough, which is called its peak-to-peak amplitude.
A point on a wave with negative amplitude is a trough. The trough is the lowest point on a wave where the amplitude is negative, representing the minimum displacement from the equilibrium position.
The measurement of a wave's magnitude of oscillation is called amplitude. It represents the maximum displacement of a particle in a medium from its rest position during one complete wave cycle.
We need a length or distance measurement here. The unit is meter or a part of it, like centimeter, millimeter.

Loudness is determined by the amplitude of the sound waves.
Loudness is the perception of sound intensity, while amplitude refers to the physical measurement of sound waves. A higher amplitude typically correlates with a louder sound perception, as it represents more energy in the sound wave. However, factors like distance from the sound source and individual hearing sensitivity also influence perceived loudness.
