Do scientists know when an earthquake can happen?
THey know most of the times. They don't know it when it happpens so suddenly, etc.
How do scientists work out the epicentre of an earthquake?
S-waves and P-waves emit from the focus (epicenter) at the same time, yet one of them is faster than the other. therefore the S waves and P waves are directly proportional to each other. So all one needs is to do the math and trace the distance between the waves and there, you have found the Focus (epicenter) of the earthquake.
How do scientists know that the Earth's core is made of a different material?
Scientists know the Earth's core is made of a different material because earthquake waves pass through liquids, like the Earth's outer core, differently than they pass through solids.
The point on earths surface where an earthquake starts is called?
Within the Earth, the focal point of the energy released in an earthquake is called the hypocentre or focus. This is where an earthquake actually begins. The place on the Earth's surface directly above this point is known as the epicentre.
What causes earthquakes in the pacific coast?
The atmosphere in the pacific begins too rot at the bottom of the coast causing a friction which makes a 'crack', hense making the earthquake
How do scientist know the exact spot where an earthquake begins?
Scientists have been planting seismographs along fault lines for decades. These tell the scientist what area has activity first. With these machines they can pin down activity within 50 feet most of the time.
Will there be a big earthquake in LA any time soon?
California sits an a variety of fault lines and it is only a matter of when, not if, a big earthquake will occur. Scientists say it's a certainty. They just don't know the exact time it will happen.

Why did scientists not know the 1989 San Fransisco earthquake was coming?

How do the scientists know that the center of the earth is hot?
By the way earthquake waves refract as they pass through it.
When was Easter Island formed?
Millions of years ago but scientists do not know the exact year.
Did the scientists expected that the earthquake hit in pacific ocean nearby northeast in 2011?
Seriously, I really do not know if they expected or not.
Is there going to be an earthquake on the 20th in christchurch?
Nobody can know that for sure. Earthquakes are unpredictable and scientists have not been able to predict them at this time.
Why do scientists use a computer to locate the epicenter of an earthquake?
Scientists use a computer to locate the epicenter because it would be dangerous to go out there and locate it.... and they never know about any after shocks......
Why most of the planets move in the same direction?
Its something about their orbit, but only scientists know the exact thing

Are there 1 and a half cows in the world?
Not that know of but there may be some scientists working on that exact hing right now!
