Because no one has yet invented a device which can tell where tension is building up between plates. No one can tell where the plates are stuck, and no one can tell when the plates will move along. This means that no one can predict earthquakes.
The world is always changing. Technological advances help us live longer, but disasters such as earthquakes and hurricanes can lower our population. Humans are all over Earth, so it's hard to accurately predict our population.
The future is difficult to predict accurately (but very easy to predict inaccurately) so allow me to predict that Africa is facing a difficult future.
Because they had a problem with earthquakes, so they wanted to predict from where the earthquake will come
Nobody knows, we can't predict earthquakes.
because the effect is in the crust so they need to go in it
yes. Many scientist have predicted earthquakes accurately before they occur, unfortunately they can only predict them a couple of seconds before they occur in your area and they are already occurring a few miles from where you live. But our government will spend a lot of money on earthquake predictions so when the big one hits there will be no money left to restore your house but there will be enough money to rebuild all the banks, savings and loans, stock brokers homes and buildings. This is similar to the 700 billion dollar bail out for the crooks that robbed the banks.
Earthquakes do not happen in stages, or are visibly predictable like hurricanes or tornadoes. For example, we can use radars and weather tools to detect them. Earthquakes on the other hand, don't happen in stages so we can not precisely predict the exact timing of the earthquake. Scientists have other ways to predict earthquakes, even thought they can not predict the precise timing of the quakes. See the question below to see how scientists (seismologists) can predict roughly when and how much damage an earthquake can impose.
They can't predict the time or the location of earthquakes. They can provide probable data on expected times and location an earthquake with better assurance than in the past but not exact times or dates.
There is none and scientests cannot predict earthquakes yet or maybe never but they can measure them after one has happened. But so far there is no solution. But it is possiable to make your house safer from earthquakes.
Earthquakes is most often caused due to colliding of plates in the Earth's crust. As these plates are moving constantly it is not easy to know when they will collide. So it is difficult to predict earthquake.
Yes, humans can predict weather with satellite technology, but it is unreliable and is often incorrect.
It gives them the information to predict the movements of the earthquake by the location it was in the time it hit and the damage it done so that data collected can help the data collectors predict where a future earthquake can and possibly hit.
