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.
The sign is if the ground starts moving or shaking or if it starts putting out smoke or gas.
its a volcano
it will explode
Not usually. It is more common for a volcano to erupt explosively and later extrude gas-depleted lava. That being said, lava domes can sometimes explode.

A volcano can explode when pressure builds up inside it due to trapped gases and magma. This pressure can be released explosively when the volcano erupts, causing an explosion.
The sign is if the ground starts moving or shaking or if it starts putting out smoke or gas.
