What do seismologists use to determine when an earthquake started?

Seismologists use the difference in arrival times of seismic waves at different monitoring stations to determine when an earthquake started. By analyzing this data, they can pinpoint the origin time of the earthquake. Additionally, seismologists use advanced computer algorithms and technology to help refine the accuracy of the timing.


Why are seismologist interested in seismic gaps?

because they like to learn about it


What do you call a person that predicts an earthquake?

You would call that person lucky. The scientists who study earthquakes are known as seismologists and they say that it is currently not possible to predict when an earthquake will occur.Technically nobody as earthquake prediction is currently impossible however seismologists will produce seismological hazard assessments in an attempt to quantify the likelihood of occurrence of a seismic event of a given magnitude occurring within a given time period on a fault.Seismologist


What is the difference of the P waves and S waves used to locate an earthquake's epicenter?

P waves, also called primary waves, are the first waves to be registered on a seismograph. The S waves, or secondary waves, are the second and slower wave to register on the seismograph. When locating an earthquakes epicenter seismologists take the first reading of the P wave, and then take the reading from the S wave. At the station of where the earthquake was recorded, seismologists draw a large circle from where the earthquakes epicenter could be. TO exactly located the earthquakes epicenter there needs to be at least 3 dfferent staions where the earthquake hit to determine its epicenter using the S and P time interval. 


What time of day do earthquakes happen?

its always night somewhere on the earth, so when earthquakes occur its technically always at night (though not necessarily where the earth is quakin). yes earthquakes can happen at any time of day.

How do you determine the difference in time between the arrival of the primary (P) wave and the arrival of the secondary (S) wave during an earthquake?

To determine the difference in time between the arrival of the primary (P) wave and the secondary (S) wave during an earthquake, seismologists analyze data from seismic sensors. They identify the first arrival time of the P wave, which travels faster, and then the later arrival time of the S wave. The difference in these arrival times is recorded, and this time interval can be used to estimate the distance to the earthquake's epicenter using known velocities of the seismic waves. This method is fundamental in locating earthquakes and understanding their magnitude.


What is the time required to determine the time for a drop, starting from rest, to reach 63 of terminal velocity?

The time required to determine the time for a drop, starting from rest, to reach 63 of terminal velocity is typically around 5 to 6 seconds.


When siesmologists record arrival times of p waves and S waves at several seismograph stations they are looking for the earthquakes?

When seismologists record the arrival times of P-waves (primary waves) and S-waves (secondary waves) at various seismograph stations, they analyze the time difference between these waves to determine the earthquake's epicenter. P-waves travel faster than S-waves, so the time gap can indicate how far away the earthquake occurred. By triangulating data from multiple stations, seismologists can pinpoint the earthquake's location and assess its magnitude. This information is crucial for understanding seismic activity and mitigating risks in affected areas.


Do Geologists use the difference in the arrival time of P and S waves at a seismograph to determine the magnitude of an earthquake?

No. Seismologists (a type of geophysicist) use the difference in the arrival time of P and S waves to estimate the distance from the seismometer station to the epicentre of the earthquake.

What is triangulation Earthquakes?

Triangulation in earthquakes refers to the method of determining the exact location of an earthquake epicenter by using data from at least three seismic stations. By measuring the time it takes for seismic waves to reach each station, seismologists can pinpoint the location where the waves originated. This triangulation method helps provide accurate information about the earthquake's epicenter and other characteristics.


Can scientist predict earthquakes?

Earthquake prediction is currently not possible, as such, seismologists will attempt to quantify the risk posed by a particular fault zone rather than state exactly when an earthquake will occur. For more information, please see the related question.


How can a travel time graph be used to find the earthquakes epicenter?

A travel time graph illustrates the relationship between the time it takes for seismic waves to travel from an earthquake's epicenter to various seismic stations. By measuring the arrival times of primary (P) and secondary (S) waves at different stations, seismologists can determine the distance from each station to the epicenter. Using triangulation, they can plot these distances on a map to pinpoint the exact location of the earthquake's epicenter, as the intersection of circles drawn around the stations will reveal the epicenter's location.
