The are a smalls earthquake..
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
Its sends lava downsloping
The first eruption was about 3.825,this was before human was alive!!
The volcano will smoke and give off ash.Lava may flow out of the vent of the volcano.

Before a volcanic eruption, magma from within the Earth's mantle rises towards the surface through cracks in the crust. As the magma makes its way upward, it can create pressure and heat, leading to increased activity within the volcano. This buildup of pressure eventually causes the volcano to erupt, releasing ash, lava, and gases.
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.
it runs dowm the side and forms rock
A pyroclastic flow.
Preferably, to a safe distance from the volcano.
