Seismic waves generally travel much shorter distances on the West Coast than on the East Coast because:

Possible Answers:

  1. Earthquakes are more frequent on the West Coast
  2. Communities are better prepared for earthquakes on the West Coast
  3. The earthquakes are of greater intensity on the East Coast
  4. The soil composition is different in the two regions

The Correct Answer:

D. Seismic waves generally travel much shorter distances on the West Coast than on the East Coast because the soil composition differs in the two regions.

Explanation:

Seismic waves can produce Ocean waves that can impact many communities nearby the sea coast. The intensity of these seismic waves ‌causes a shaking moment during the earthquake.

They arise from the earth’s center and then travel to other parts in a circular motion. In the case of surface waves, they travel to the only surface and can cause more significant harm.

The body waves generally travel deep into the earth’s surface and also on the earth’s surface. Scientists typically use this type of wave to figure out the earthquake epicenter.

Several subcategories of seismic waves are responsible for causing different-intensity damage to the soil and nearby communities. Seismic waves can co-terminate additional damage like liquefaction, faults, Tsunamis, seiche, and landslides.

Seismic waves travel longer on the West Coast than on the east coast because of different soil compositions in other regions. The topography of an area is responsible for impacting the seismic intensity.
