GEOG 101 Lecture Notes - Lecture 14: Inclinometer, Epicenter, Asthenosphere
Document Summary
Aftershocks are a result from rocks in the epicenter that find some sort of equilibrium. Needle starts going crazy as earthquake begins. The needle is secured by a weight. The base is secured to the earth. Resistance within the needle when the earth starts to move, causes scatter to occur on the paper of t"he machine. The amount of damage to human landscapes. We know where they are most likely to occur, but don"t know where they. We can predict based on history, but we cannot predict when they will occur. Sometimes they occur in the middle of plates (where we think there is. Edges of plate greatest potential for earthquake activity. Forms at the end of a central vent from the asthenosphere and upper mantle . Crater is a circular depression near summit. Movement of tiltmeter is an indicator of potential volcanic activity. Can indicate if a slope is unstable.
