Most geologist consider a particular fault to be an active fault if it has moved during the past 10,000 years of the Holocene Epoch. An inactive fault is one that hasn't moved during the past 10,000 years of the Holocene Epoch.

Active faults are faults that have experienced recent movement and are likely to do so again in the future, posing a seismic hazard. Inactive faults, on the other hand, are faults that have not moved in a significant way for a long time and are not likely to generate future seismic activity.

What is differentiate active and inactive faults?
Active faults can generate earthquakes and represent sources of seismic energy. Inactive faults can no longer generate earthquakes but did so in the past. +++ They can, but really the earthquake is the effect of the movement on the fault, so not the defining mechanism. ' An active fault is one still moving (albeit usually in small, irregular steps over millions of years); an inactive fault is stable. If a new phase of tectonic stresses arrive, an inactive fault can be 're-activated', in many cases with the movement in the opposite direction. A fault is a fracture with displacement, and that movement is of the rock on one side of the fault-plane across the other.
What is the difference between Active and inactive faults?
An active fault is a fault that has displayed recent seismic activity, while an inactive fault has not displayed recent seismic activity.Do not be fooled by the word "recent," however, as we are talking about "recent" from a geological perspective, which is much different from a non-geologic perspective. Because of the fickle nature of plate tectonics, an active fault could have earthquakes as often as once every few years or once every one thousand years. Conversely, it's very hard to call a fault inactive if we don't know it's quake history, and for some faults, geologists will wait ten thousand years in between quakes to call them inactive.There are a variety of techniques that geologists can use to help them determine the frequency of earthquakes among faults, however. If a history of quakes coming from the fault are available, scientists can look at the average period of time in between quakes to determine whether a fault is presently "active" or "inactive." Scientists can also measure creep among fault lines to check for seismic activity.There really is no way to concretely define a fault as "active" or "inactive" (especially because inactive faults can suddenly become active again), but it's more or less safe to say that if a fault hasn't shown tectonic activity for about 5,600 years, it's probably inactive.++Just to add to that explanation, if movement occurs on long-quiescent fault in a new phase of tectonic activity, the fault is described as 're-activated', and the new movement can be the opposite to the original.
Why are faults sometimes referred to as active boundaries?
because tectonic plates actively move and shift along faults
What is one structure that you would find at an active continental margin that you would not at a passive?
You will find active faults and, if the margin is convergent, volcanoes.
What are the conditions for ammonia molecule to be IR active?
An IR Active stretch simply means that the vibrations of the molecule result in an overall dipole of the molecule. If a stretch has a dipole, it is IR active. If a stretch does not have a dipole. then it is IR Inactive.

Is nickel an active element or inactive element?
Is nickel active or inactive
Can you get active and inactive earthquake zones?
yes you can get active and inactive earthquakes zones.
What is active and Inactive air in primary schools?
There is no such thing as active/inactive air.
Is magnesium active or inactive?
Magnesium is an active element. It is a highly reactive alkali earth metal that readily forms compounds with other elements due to its tendency to lose electrons and achieve a stable electron configuration.
What is the root of inactive?
Active
What does inactive means?
Not active.
Is Big Cave Volcano active or inactive?
inactive
Is mount Arayat an active or inactive volcano?
inactive
What is the active and inactive volcanoes?
Active means it is errupting. Inactive means it is NOT errupting. Prety simple.
What is a passive fault?
A passive fault is a fault that is not currently experiencing movement or does not have the potential to generate seismic activity. These faults may have been active in the past but are now considered inactive or dormant.
