A seismograph station recorded the arrival of the first P-wave at 7 32 pm From an earthquake that ocvured 4000 kilometers away What time was it at the station when the earthquake occurred?

P-waves, or primary waves, travel faster than other seismic waves, typically at speeds of about 6 to 8 kilometers per second. If the earthquake occurred 4,000 kilometers away and the P-wave arrived at 7:32 PM, it would have taken approximately 500 to 667 seconds (about 8 to 11 minutes) to reach the station. Subtracting this time from 7:32 PM, the earthquake likely occurred between 7:21 PM and 7:24 PM at the station.


If a p wave arrives at a seismograph station at 907 am and the S waves arrives at the same seismograph stations at 909 an about how fare is that station from the epicenter of the earthquake?

To estimate the distance from the seismograph station to the earthquake epicenter, we can use the typical speed of P waves (approximately 6 km/s) and S waves (approximately 3.5 km/s). The time difference between the P wave and S wave arrival is 2 minutes (or 120 seconds). Given that P waves travel faster, we can calculate the distance using the time difference, which would be approximately 360 km from the epicenter to the station.


How long did the 1923 kamchatka earthquake last?

The 1923 Kamchatka earthquake, also known as the Great Kamchatka earthquake, lasted only about 10 minutes. It occurred on February 3, 1923, and had a magnitude of 8.2. This powerful earthquake caused significant damage in the Kamchatka Peninsula region.


How far did the plates move in the 1964 Alaskan earthquake?

about 100 or less kilometers. the Alaskan earthquake lasted about 5 minutes and had a magnitude of 9.2 in Richter scale. that was a very destructive earthquake since it is the third strongest earthquake read by the seismograph in the world and the strongest in north America.


If an earthquake occured in seattle Washington how long would it take for the first seismic waves to arrive at a seismograph station in Miami Florida?

It would take about 5-7 minutes for the primary or P-waves to reach a seismograph station in Miami, Florida from Seattle, Washington. These waves travel faster than secondary or S-waves, which would arrive a few minutes later.


How long did the 1964 Alaska earthquake last?

The 1964 Alaska earthquake, also known as the Great Alaska Earthquake, lasted approximately 4 minutes. It occurred on March 27, 1964, and is the most powerful recorded earthquake in North American history.


How far from an earthquake epicenter is an observer who measured a difference of eight minutes 40 seconds and arrival times of p waves and s waves?

To calculate the distance from the earthquake epicenter based on the difference in arrival times of P-waves and S-waves, we use the fact that P-waves travel faster than S-waves. The average difference in arrival time is approximately 1 minute for every 8 kilometers (5 miles) from the epicenter. Given an arrival time difference of 8 minutes and 40 seconds (which is 8.67 minutes), the distance would be about 69.36 kilometers (or approximately 43.2 miles) from the epicenter.


How long was the great Alaska earthquake?

The Great Alaska Earthquake, also known as the Good Friday Earthquake, lasted for about four and a half minutes. It occurred on March 27, 1964, and remains one of the most powerful recorded earthquakes in history.


How long did the L'Aquila earthquake in Italy last?
