The are a smalls earthquake..
magma falls from underground to form an opening in the volcano
eruption
An eruption from the side of a volcano is called a lateral eruption. This usually happens at rift zones where a volcano breaks apart. It is also called a flank eruption. If the volcano is explosive, it may also be called a lateral blast.

magma flows up to form the eruption
The first eruption was about 3.825,this was before human was alive!!
Its sends lava downsloping
The volcano will smoke and give off ash.Lava may flow out of the vent of the volcano.
To a limited degree, yes. Scientists can look for signs of pressure building and magma moving underground.
The cause of St Helens Volcano Eruption in the year 1980 was a 5.1 magnitude earthquake. The volcano didnt erupt for 120 years before this eruption .. so all the magma in the magma chamber had alt of pressure and was pushed out. the volcano was in a position where plates move.
Preferably, to a safe distance from the volcano.
it runs dowm the side and forms rock
