High Blood Pressure. By lowering blood pressure, blood pressure medications (like clonidine) are thought to decrease the risks that occur with long-term high blood pressure (see Effects of High Blood Pressure). Clonidine does not, however, cure high blood pressure. It can be used alone or in combination with other blood pressure medications.
Add your answer. Do s-waves move side to side and do p-waves move up and down? In one book it says p-waves move up and down and another it says p-waves move side to side. And also s-waves, one book says they move up and down and another side to side! so what is it? and which causes the most damage?
When an earthquake occurs, it releases energy in the form of seismic waves that radiate from the earthquake source in all directions. The different types of energy waves shake the ground in different ways and also travel through the earth at different velocities. The fastest wave, and therefore the first to arrive at a given location, is called the P wave. The P wave, or compressional wave, alternately compresses and expands material in the same direction it is traveling. The S wave is slower than the P wave and arrives next, shaking the ground up and down and back and forth perpendicular to the direction it is traveling. Surface waves follow the P and S waves.
