PLEASE TELL ME!!!
how can you tell if a volcano going to erupt
they give warnings to tell them that its about to erupt
The number of times a volcano erupts varies greatly and depends on various factors such as its location, type, size, and geological history. Some volcanoes may erupt once and remain dormant for centuries, while others may erupt frequently over a short period of time. It is not possible to predict the exact number of times a volcano will erupt in its lifetime.
The sign is if the ground starts moving or shaking or if it starts putting out smoke or gas.
Not just by looking at it. Scientists do detailed analysis using seismographs, and chemical samples of gas and,where possible, lava. These can point to whether or not a volcano is getting read to erupt.
It depends on what type of volcano they are; Active - very likely to erupt e.g Mt Etna Dormant(sleeping) - a volcano which has not erupted for many years. For example, Mt Pinatubo erupted in 1991 after 500years of dormany Extinct - a volcano in which has not erupted for many thousand or millions of years
Any of the volcanoes around Portland and Seattle could blow at any time. In Alaska, volcanoes are erupting quite regularly. It is really difficult to tell which US volcano is likely to erupt, next. But . . . Mt. Rainier, in the Seattle area, is expected to erupt in our lifetimes, and the immense volcano in and under Yellowstone Park could erupt at any time. There are a couple of volcanos in northern California that could erupt, as well.
They do occasionally, and they sometimes help vulcanologists. This is because volcanoes generate earthquakes, and analyzing patterns in these earthquakes can help to tell if a volcano is likely to erupt soon.

It doesn't erupt
you tell me
volcanoes is the natural fenomenom most difficult to predict. That duty belong to the people at the seismic intitutions and seismic observatories. They are called geologists. Volcanologists monitor information from sensors near volcanoes to provide short-term forecasts of possible eruptions or changes in the course of existing eruptions. These sensors detect physical changes such as earthquake activity, shape of the volcano, and the release of volcanic gases.
