It could be days or YEARS before the major earthquake. Plate tectonics are always moving.

How long did it take to recover from earthquake Shaanxi?
It took over ten years to recover after the Shaanxi earthquake
Why do scientists think that seismic gaps are areas where future earthquakes are likely to occur?
Most earthquakes occur as a result of "stick-slip" behavior. As two plates move past each other they stick to each other along the fault and build up stress. Eventually the plates slip along part of the fault, releasing that stress as an earthquake. The longer part of a plate goes without an earthquake, the more stress builds up, and the more energy is available for a large earthquake. Scientists think these seismic gaps are areas where the plates have been stuck for a long time and so have built up stress for a very large earthquake.
Long wave caused by an underwater earthquake?
Tsunami
How long was the great Kanto earthquake?
about 4 to 10 min
How long did the 1923 kamchatka earthquake last?
5 minutes
How long after an earthquake does nausea occur?
There is no requirement for nausea to occur due to an earthquake or any other natural phenomenon.
Who can you get prior information about earthquake?
Predicting earthquakes is quite difficult. Long term predictions are imprecise but possible. They can estimate within 100 or so years when an eruption will occur. They study slip rates, slip magnitudes, and fault history. Short term predictions are precise, but very difficult. It is based on fluid pressure, gas release, changes in magnetic fields, foreshocks, and gaps in earthquake records.
How long did the tangshan earthquake occur?
14-16 seconds
How long do after shocks happen after an earthquake?
By this you could mean 2 things:How long after the main earthquake do aftershocks occur?A: This depends on the magnitude of the main quake, and the faultline and how much tension there is between the tectonic plates.2. For how long after the main earthquake do aftershocks occur?A: This again depends on the magnitude of the main earthquake and the faultline.
How long does it most likely take for an earthquake to occur?
it takes well no one ever knows
How many people died because of the first earthquake?
The first earthquake happened long before any humans were even alive, so it wouldn't kill any people.
Where was the first earthquake in north America?
That is impossible to determine. Earthquakes have been occurring since long before there were people around to record them.
When did the strep throat first occur?
It first occurred long before recorded human history.
How long was the average earthquake time for Long Beach?
the average earthquake time for long beach depends on how the high or low the magnitude range is.
What actions did people take that increased the effects of the Haiti earthquake?
Inaction is probably the greatest cause of the scale of the Haitian earthquake catastrophe. For whatever reason -- poverty or corruption -- Haiti had little or no earthquake building codes, which meant their building were extremely vulnerable to earthquakes. Building construction was exceptionally shoddy, even for not having earthquake codes. It is important to note that most of the U.S. has relatively little or no earthquake building codes. The Pacific coast states, being seismically more active, do, but significant earthquakes do occur -- albeit more rarely -- in the east. New York City, for instance, did not adopt an earthquake code until 1995, and it only applies to new buildings, and it only accounts for a 5.5-richter earthquake (the Haiti Quake was 7.0, more than ten times as powerful). Most high rise buildings in New York were built long before this, and may be very vulnerable to a Haiti-scale earthquake which can occur in New York.
Has Haiti recovered yet?
If you mean has Haiti recovered from the earthquake in January 2010, as of March 2010, no, Haiti has not recovered yet. There is a lot of damage from the earthquake and Haiti being a poor country, it will be a long time before it can recover.
When does Perinatal asphyxia come?
Perinatal asphyxia can occur a long time before birth, shortly before birth, during delivery, or after birth
