Earthquakes and volcanic eruptions are extremely hard to predict because of their irregularity. This is due to the butter fly effect. For example, in California there had been a volcanic eruption every 30 years since the start of their records, so they a few years ago when it was scheduled to happen the government spent millions on "earthquake-proofing" the area. Nothing actually happened. The main way to predict earthquakes and volcanic eruptions is to look for patterns in the past but it is really not an accurate or reliable method. Earthquakes are a lot harder to predict as they can happen at any point down a convergent or conservative plate boundary spontaneously, where as with a volcano you can study it and look for signs such as bulges or changes of gas composition in the area that could indicate when it will erupt. However new methods of detection are being tested, the strangest being the use of some animals, snakes the most common, that behave in peculiar ways just before an earthquake. Breakthroughs like these and the use of new technologies, like GPS to monitor irregularities in the the shape of volcanoes, will make the prediction of earthquakes and volcanic eruptions much easier in the future

An eruption requires the movement of large amounts of magma over a period of time. This causes many seismic shocks of varying magnitude prior to the eruption.

Many earthquakes consist of a single sudden rupture of the fault followed by after shocks, but no preshocks.

the earthquake is when tectonic plates move and collide with force that takes many years to happen so it can be predicted when it would happen and a volcanic eruption is when to much stress is put on the earth and it is more spontaneous and is harder to predict because it is all about the hold of the earth over the lava and if there is release or not

It is very difficult to predict volcanic eruptions. The main reason is the fact most of them have been dormant for decades and lack frequent activity which might be used for prediction.

Because the eruptions are random. But, normally scientists can give an approximation.

What conditions makes it difficult to predict the occurrence of the next earthquake?

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.


Why is it difficult for geologists to make short term predictions about earthquakes?

There is no way for them to predict one.


Why do scientist want to be able to predict earthquakes?

Scientists want to be able to predict earthquakes to save peoples lives.


Can scientist predict large earthquakes?

Scientists are able to predict large earthquakes to a certain extent. With the use of certain statistical methods, many earthquakes are able to be predicted.


Why tsunamis are difficult to predict?

Tsunamis are difficult to predict because the earthquakes that cause them are difficult to predict. It takes a massively powerful earthquake to displace the amount of water needed to cause a tsunami.

What makes predicting earthquakes so hard?

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.


Why is it important for scientist to develop ways to predict earthquakes?

It is important for scientists to develop ways to predict earthquakes. By it they can measure when the next one would be.


Do scientist have the power to control or predict earthquakes?

Scientists have no power to control earthquakes, nor to specifically predict them, but a logical area that the earthquakes would take place is along the plates of the earths crust. (Their shifting leads to earthquakes)
