Actually it is quite common. Water heated by any method can do this (under
the right circumtances). In Labs they use special triangular stones in the
bottom of vessels expected to boil so it will bubble. I've had the water
gush out of a cup when I added a tea bag to microwaved water. It bubbled
up
like a soda that had salt poured in it.

The smoother the interior surface of the container the more readily this
can occur. That's why the triangular stones.

From Scopes

"Odds are, you'll go through life without ever viewing this phenomenon
first-hand, and if you're one of the rare few who does get to see it, you
will likely not be harmed by the experience (that would take you standing
right over the cup at the instant it happens and the liquid bolting up and
hitting your skin)."

And
"If you're really worried about this happening to you, follow the advice and
leave some non-metallic object (such as a wooden spoon or stir stick) in the
cup when you boil water in the microwave. It may not be necessary, but it
won't hurt anything either. Peace of mind rarely comes so cheaply."
