If the diode shorts, it Will cause excessive ripple from the half wave
rectification.
I suspect that the failure mode is an open causing the remaining diode
to carry the full current, which will cause its eventual failure.
In any case, paralleling two diodes without some form of resistance in
series will be a prescription for failure.

When you say 'blow' are you saying it short circuits internally or open
circuits internally due to the event ?
