Those are circumventable. Trigger the seismic sensors (before making access to the vault) a bunch of times until the alarm gets ignored or the sensors get temporarily disabled.
The biggest brazilian heist was also made using tunnels, but they got away with a lot more money than those guys and most of the criminals involved were never captured.
There were tunnel bank robberies like these in the Black Echo, the first Bosch novel.
Not the first underground break ins. I think there's one in a Sherlock Holmes story. But seems like banks could just monitor vibrations to prevent this attack.
