How Would This Diagram Change If The Seismic Station Was Farther From The Earthquake

A watch gets upgraded to an advisory and then a warning if a tsunami is detected by sensors or humans. Most seismic waves can be described as a series of repeating crests and troughs.

Noaa will declare a tsunami watch normally just a few minutes after the earthquake occurs.

How would this diagram change if the seismic station was farther from the earthquake. They are generated near the surface and only compress the rock as they travel. Sign up to access the rest of the document. Some seismic waves travel on the surface and are called surface waves.

They compress and then expand the rock in the direction the wave travels. This preview has intentionally blurred sections. How would this diagram change if the seismic station was farther from the earthquake there would be a larger gap between the arrivals of the p and s waves on this time travel curve if a large earthquake is 400 km away from the station what can you say about the arrivals of the p and s waves.

29a seismic station recorded an earthquake with an epicenter distance of 4000 kilometers. The material within the wave moves long distances along with the wave. The three types of seismic waves are p s and l waves.

Earth science new york regents august 2005 exam base your answers to questions 63 and 64 on the diagram below which shows two seismogram tracings at stations a and b for the same earthquakethe arrival times of the p waves and s waves are indicated on each tracing. This diagram indicates that. The arrival time of any wave is based upon its speed.

Using this nomogram what is the magnitude of an earthquake that is 500 km from a seismic station and has an amplitude of 02 mm. The seismic waves are generated by the earthquakes and radiated from the focus. 30base your answer to the following question on the diagram below which represents zones of earths interior identified by letters a through e.

P waves travel faster if the earthquake is larger whereas s waves are slowed down by larger earthquakes. They travel slower than other seismic waves. Step 1 of 4 seismic wave are generated by the sudden explosions and earthquakes.

Sign up to view the full version. The worldwide network of seismometers allows computers to broadcast earthquake magnitudes and locations within minutes of the event. They displace the rock back and forth in a direction that is perpendicular to their travel direction.

This is the end of the preview. No s waves arrive directly at seismic station a because. P waves are faster so they pull away form s waves with increasing distance from the epicenter.

If the origin time of the earthquake was 1100 am what time did the p wave arrive at the seismic station. Cthe distance to seismic station a is too great dseismic station a is located on glacial ice 4the cross section of earth below shows a p wave moving away from an earthquake epicenter to seismic station a. Some surface waves shuffle material side to side while others move material up and down.
