It could be days or YEARS before the major earthquake. Plate tectonics are always moving.
A long wave caused by an underwater earthquake is known as a tsunami. Tsunamis are generated when an earthquake displaces large volumes of water, creating powerful waves that can travel long distances across the ocean at high speeds before reaching shore. These waves can cause widespread devastation and loss of life when they make landfall.
The 1989 Loma Prieta earthquake lasted about 15 seconds. It was a magnitude 6.9 earthquake that caused significant damage in the San Francisco Bay Area.
Earthquakes occur at long narrow fractures in the Earth's crust called faults. As tectonic plates shift past each other, stress builds up at these faults until it is released in the form of an earthquake. Movement along the fault line causes the ground to shake, resulting in seismic waves that can be felt at the surface.
The magnitude of the 1933 Long Beach earthquake was approximately 6.4 on the Richter scale. It caused significant damage to buildings in Long Beach, California, resulting in 115 casualties.
The Great Kanto earthquake, which struck Japan in 1923, lasted for about 4-10 minutes.
There is no requirement for nausea to occur due to an earthquake or any other natural phenomenon.
14-16 seconds
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.
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.
it takes well no one ever knows
The first earthquake happened long before any humans were even alive, so it wouldn't kill any people.
A long wave caused by an underwater earthquake is known as a tsunami. Tsunamis are generated when an earthquake displaces large volumes of water, creating powerful waves that can travel long distances across the ocean at high speeds before reaching shore. These waves can cause widespread devastation and loss of life when they make landfall.
That is impossible to determine. Earthquakes have been occurring since long before there were people around to record them.
It first occurred long before recorded human history.
the average earthquake time for long beach depends on how the high or low the magnitude range is.
When a strong earthquake occurs under the sea, it can lead to a tsunami. The earthquake can cause the seafloor to uplift or subside, displacing a large amount of water that then generates massive waves. These tsunamis can travel long distances across the ocean and cause widespread devastation when they reach coastal areas.
Perinatal asphyxia can occur a long time before birth, shortly before birth, during delivery, or after birth
