Seismographs record seismic activity in volcanic regions as predictors of volcanic activity. Additionally, GPS instruments record the rise and fall in surface features which may indicate a possible building of magmatic pressure underground.

What is the device used to predict volcanoes?
Volcanoes eruptions cannot be predicted; some sign are perhaps an increasing seismic activity, increased release of volcanic gases, increased temperature.
What do we monitor about volcanoes to predict eruptions?
In order to try to predict a volcanic eruption, scientists monitor the distribution of earthquakes near the volcano, the quantity, temperature, and composition of gas emissions, and look for deformation of the volcano itself. All of these can be used to determine if magma is moving underground, how close it is to the surface, and even how obstructed it is.
Is the heat of a volcano used to measure the Richer Scale?
No, nothing is used to measure the Richter scale. The Richter scale is used to measure the intensity of earthquakes.The Volcanic Explosivity Index (VEI) is used to provide a relative measure of the explosiveness of volcanic eruptions.
What did Krakatoa measure on the Richter scale?
Nothing. The Richter scale is used to measure the intensity of earthquakes, not volcanic eruptions. The eruption of Krakatoa in 1883 was a VEI 6 in the volcanic explosivity index.
What conditions makes it difficult to predict the occurrence of earthquakes?
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

What is molten rock used for after when erupted?
There is no use for molten rock from volcanic eruptions.
What is a seismograph for?
They are used to measure earthquakes and volcanic eruptions by recording seismic activity.

What was the Richter scale for the Kobe earthquake?
It did not have a Richter scale rating. The Richter scale is used to rate earthquakes, not volcanic eruptions. Volcanic eruptions are rated on the Volcanic Explosivity Index. The 1991 eruption of Mount Pinatubo was a VEI 6, described as a colossal eruption.

What does does seismograp mean?
You mean a seismograph =)........A seismograph is a instrument that measures motions of the ground.They are usually used to detect earthquakes and volcanic eruptions.
Why south Africans are not used to volcanic eruptions?
There are no more ACTIVE volcanoes in Africa.
What is the difference between a tiltometer and a seismometer?
A tiltometer measures the bulging of a volcano, which is how much the volcano is 'growing' wider and wider due to the magma chamber within a volcano filling with magma, if the tiltometer is reading that the volcano is bulging massively then this could be because it is about to errupt so it can be used to predict volcanic eruptions. A seismometer on the other hand measure tremors before an eruption due to magma movement and it can be used to predict earthquakes due to foreshocks.
What is follicular study Can it be used to predict ovulation When is this study done in the cycle?
Its is very easy process it is done 11th day of periods its no painfull
