People on the lower end of that spectrum, the bottom 10% to be exact, make roughly $59,000 a year, while the top 10% makes $134,000. JohnathanSmith2. Seismometers allow us to detect and measure earthquakes 4 What are the two way scientists measure earthquakes? The first kind of body wave is the P wave or primary wave. Scientists further study the seismic waves recorded by pen and make estimates about the intensity of the earthquake. How do scientists measure the size of earthquakes? The pen also starts vibrating and paper starts moving under the pen recording the movement of the pen. They often compare information from all over the world. To determine the direction each wave traveled, scientists draw circles around the seismograph locations. Generally, a seismograph consists of a mass attached to a fixed base. The pen records the movement on the drum. . The cookie is used to store the user consent for the cookies in the category "Analytics". The strength of the earthquake is determined from the measured amplitudes and the distance to the hypocentre of the earthquake. Seismic phenomena are generally explained as the result of interactions and other processes at or near the edges of a few large mobile plates of lithosphere that spread apart at the ocean ridges where new surficial materials arise, slide past one another along the large strike-slip faults, and converge at the island . Seismographs are the key tool of seismologists since they make it possible to collect and to record the vibrations of the Earth. : P wave seismograms to predict volcanic eruptions Quizlet One of the can! The velocity of s waves going through the asthenosphere decreases, which tells us that peridotite contains a few percent partial melt, but not enough to stop s waves. by converting vibrations due to seismic waves into electrical signals Seismographs detect seismic waves and use this data to study the length and depth of the waves.
