A seismograph can be defined as an instrument that is used for monitoring, detecting and recording the direction, duration and magnitude (intensity) of an earthquake in a particular geographical location. Also, a seismogram is the graphical representation of the parameters or quantities such as wave amplitude measured by seismograph.
In this scenario, Ramon knew that the wave amplitude on a seismogram measures how severe an earthquake is. In a magnitude 8 earthquake, the waves are ten (10) times larger than a magnitude 7 earthquake. However, the energy released is two (2) times greater.
Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.
