NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the sea floor such as shipwrecks, and map the sea floor itself. There are two types of sonarâactive and passive.
A seismograph is only one tool scientists are using, in an attempt to LEARN how to predict volcanos and earthquakes. If the technique had already been developed, then many lives would have been saved in the last several years. What a seismograph detects is the movement of ground in the area of the instrument. They are pretty sensitive and can detect, even very slight movements, such as the passing of nearby automobiles, and, man made explosions many miles away.
