A seismograph is used to detect vibrations and motions in the Earth's crust. These tremors are usually due to friction between tectonic plates (earthquakes) or huge powerful volcanic activity. - hope that helps

The easiest way to distinguish between volcanic ash and volcanic dust particles is to compare their?

The easiest way to distinguish between volcanic ash and volcanic dust particles is to compare their diameter. Seismographs can be useful in predicting volcanic eruptions because they measure earthquake activity.


How is Dr. MuKasa able to study Earth's interior without actually seeing it?

By "looking" at it with seismic waves (instead of light) using arrays of seismographs (instead of his eyes). Using modern supercomputers greatly simplifies analysis of this information and can even generate pictures or can make models using 3D printers that can be examined and looked at.


Explain how scientists use seismic waves to map the earth's interior?

scientists use seismic waves to map earths interior by seismographs that measure the times at witch seismic waves arrive at different distances from an earth quake.


What information can scientists get by studying seismographs from different locations?

Each of a pair of seismic stations can determine the direction a seismic wave came from, and if that data is plotted on a map, the location where the lines cross will be the epicenter of the quake.
