Bilge keels are passive stability systems. On commercial shipping the bilge keel is the form of a strake, or small keel or blister, running along much of the length of the hull. They are typically fitted one on each side, low down on the side of the hull, so as not to increase the draft of the vessel.
Intensity is a measure of the strength of shaking experienced in an earthquake. The Modified Mercalli Scale represents the local effect or damage caused by an earthquake; the intensity reported at different points generally decreases away from the earthquake epicenter.
Keep in mind that too much color vibration and intensity can be hard to look at. What is intensity? Again, when we speak of the intensity of any given color we refer to its brightness or dullness. The intensity scale is made up of hue and tone. Hue is when a color is fully saturated, meaning it has not been neutralized by its compliment. We can call these colors that have the highest possible level of saturation pure hues.
