What disadvantages do subterranean shelters have?
Answer There is no escape if the entrance is breached, and poor construction could make it fatal.
Unless you have built a secondary opening, you are a sitting duck if your shelter is breached. Another danger is that a badly constructed underground structure or ventilation system could suffocate you or collapse, and if nobody knows where you are, no help will come.
