The solutions to our problem are:
This should not be a very big problem because a volcano on mars has not erupted since the time before humans. Stainless steel- We would cover stainless steel all over the volcano. The steel would prevent lava from erupting out of the volcano because, most of the steel will be on the top of the volcano. If the steel lights on fire, we can use Alois' hose. Every week, Alois would check for cracks on each volcano. After one eruption, a cover of obsidian gets created and we don't need the stainless steel cover. And if the steel somehow lights on fire we have cameras set up.
