Question
For each of the towns located in this region, determine what hazards likely accompanied the recent earthquake. Be sure to consider the topographic and geologic setting of each town and the detailed descriptions. Then interpret whether each town has a high, moderate, or low hazard risk relative to the other towns, and circle your choices in the table below. You will also need to explain your reasoning in the space provided in the table. NOTE: Do NOT assume that liquefaction occurred unless there is information in the description that implies the town is susceptible to this hazard.Explanation / Answer
In general, risk of an earth quake depends on its strength of energy released during earthquake which is measured as its magnitude. In general magnitude decreases with increasing distance from the source point. In given situation, volcano is the source place of earthquake. Thus, the magnitudes for the given cities are given as,
Sandpoint: Since this place is very far from the errupted place volcano, it experiences low magnitude of earthquake with 4.0-4.9. Groud shaking occurs.
Hillside: It is some what near to the vocano than the sand point. Thus, this place eperiences moderate earthquake, which results in land slide and other slope failures. Magnitude is in between 5.0-5.9.
Cascade village: It is some what near to the vocano approximately as Hillside. Thus, this place eperiences moderate earthquake, which results in land slide and other slope failures. Magnitude is in between 5.0-5.9.
Mesaview: Both are approximately near to the volcano. Hence, these places experience high magnitude earthquakes. Thus, destruction occurs. Magnitude is in between 6.0 to 6.9.
Ashton: Since this place is very near to the volcano, liquifaction occurs, which refers to the total destruction of formations with very strong magnitude.
Cliffside and riverton: Both these places situated at distances of cascade village and hillside, these two too experience the moderate earthquakes with landslides and slope failure.
White sands: This place is situated at very far distance from the volcano, it experiences small magnitude of earthquakes as sandpoint with ground shaking.
