What was the difference of time between the earthquake and tsunami of japan?
the tsunami followed as a result of the earthquake at 3.45 p.m., local time-jst
Is the earthquake still going on?
Earthquakes, can happen at any time, so it is impossible to tell whether or not an earthquake is happening at this current moment.
What can the s-p interval tell us about an earthquake?
The S-P interval can tell us the distance to the earthquake epicenter. By measuring the time difference between the arrival of the S and P waves on a seismogram, seismologists can calculate the distance based on the known velocity of seismic waves through the Earth.
What is the difference in arrival time between P and S waves equivalent to?
The time difference in arrival between P and S waves can help determine the distance to an earthquake epicenter. For each second of difference, the earthquake is roughly 7.5 kilometers away. So, a time difference of, for example, 10 seconds would indicate the earthquake is approximately 75 kilometers away.
How can you calculate the origin time of an earthquake?
The origin time of an earthquake is determined by analyzing the seismic waves recorded by multiple seismometers. By comparing the arrival times of the waves at different stations, scientists can calculate the time it took for the waves to travel from the earthquake source to each station, thus pinpointing the origin time of the earthquake.
How is the distance between the seismic station and the earthquake epicenter determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
What time did haiti earthquake begin?
between 2-3 pm EST
How do you find the lagtime of an earthquake?
To find the lagtime of an earthquake, subtract the origin time of the earthquake from the arrival time of the seismic waves at a specific location. This lagtime represents the delay between the earthquake occurrence and the arrival of seismic waves at that location. The lagtime is a crucial parameter for determining the distance of the earthquake epicenter from the recording station.
What is the relationship between lag time and distance from an earthquake's epicenter?
The lag time between the arrival of primary (P-wave) and secondary (S-wave) seismic waves increases with distance from an earthquake's epicenter. This relationship is due to the differing speeds at which these waves travel through the Earth's layers. By measuring this lag time, scientists can estimate the distance to the earthquake's epicenter.
How much time was there between the earthquake and the 2011 tsunami?
There were only minutes(3-4)
How many days does it take for a volcano to erupt after an earthquake?
There is no set time frame for a volcano to erupt after an earthquake. Some volcanoes may erupt shortly after an earthquake, while others may not show any activity for a long period of time. The relationship between earthquakes and volcanic eruptions is complex and varies depending on the specific characteristics of each volcanic system.
Is it true or false that the closer an earthquake the greater the time between the arrival of P waves and the arrival of S waves?
False. The closer an earthquake is, the shorter the time difference between the arrival of P waves and S waves. P waves travel faster than S waves, so the time interval decreases as the distance to the earthquake epicenter decreases.
