As the vibration propagates, it loses energy and ultimately fades away. The most powerful seismic waves, generated by the most powerful earthquakes, can go
around the Earth for several days
. Surface waves generated by a powerful earthquake can travel several times around the world.
How far away can an earthquake wave reach?
A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as
60 miles
from where it occurred, and it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake usually can be felt as far as 300 miles from where it occurred, and sometimes causes damage out to 25 miles.
How far can as wave travel?
The components with the longest periods could be moving at
more than 35 miles per hour
. These waves will travel thousands of miles until they bump into a shoreline or an island or a reef that makes them break and lose their energy.
Which type of seismic waves travel the farthest?
The surface waves
are generally the largest recorded from an earthquake. Body waves in the earth’s interior lose their amplitude rapidly as they get farther from the earthquake because they spread out inside the volume of the earth.
Why do P waves travel faster?
P-waves travel 60% faster than S-waves on average
because the interior of the Earth does not react the same way to both of them
. … As the interior of the Earth is almost incompressible, P-waves transmit their energy quite easily through the medium and thus travel quickly.
How far did the S wave travel in 17 minutes?
| Wave Type Distance traveled from epicenter (km) Travel time | S 5200 15 | S 1700 6 | S 6000 17 | S 1100 4 |

How long would it take this wave to travel 5000 km?
to travel 5,000km? Go to the chart! Go to the chart! The recording station tells us it took
6 minutes and 20 seconds
for the P-Wave to reach them.
Where do P-waves travel the fastest?
Because the
earth’s mantle
becomes more rigid and compressible as the depth below the asthenosphere
Where do seismic waves travel slowest and fastest?
There are two types of body waves:
P-waves travel fastest and through solids, liquids, and gases
; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
What are the 3 types of waves in an earthquake?
There are three major kinds of seismic waves:
P, S, and surface waves
. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. A P wave is a sound wave traveling through rock.
What wave causes the most damage?
Answer and Explanation:
Surface waves
are the seismic waves that cause the most damage. Surface waves are named as such because they move along close to the surface of the Earth.
How fast do P waves travel?
P-waves are the first waves to arrive on a complete record of ground shaking because they travel the fastest (their name derives from this fact – P is an abbreviation for primary, first wave to arrive). They typically travel at speeds
between ~1 and ~14 km/sec.
Which wave is most destructive?
Of the two types of surface waves,
the L-waves
are the most destructive. They can literally move the ground beneath a building faster than the building itself can respond, effectively shearing the base off of the rest of the building.
How long does it take as wave to travel 4000 km?
For example, this graph tells you that if an earthquake epicenter is 4000 km away, the P-wave will take
7 minutes
to get to you.
How long does it take as wave to travel 2000 km?
In a solid such as rock, the primary wave can travel at 5 km/sec; it would take 400 seconds, or about
6.7 minutes
to travel 2,000 km. If traveling through water, the wave travels at about 1.45 km/sec and would need 1,379 seconds (23 minutes) to travel 2,000 km.
How long would it take for the first S wave to arrive at a seismic station 4000?
How long would it take for the first S-wave to arrive at a seismic station 4,000 kilometers away from the epicenter of an earthquake?
