Your best option's when dealing with a Volcanic eruption should be an evacuation, but if you aren't partaking in that evacuation, staying in place is your best option.
Three dangers could possibly result from a volcanic eruption. Magma is the least of your worries, but the Ash and poisonous gases are.
