Well, actually, nothing out of the ordinary in the way of disasters!
What is happening is not of the physical world, but of the spiritual and, in particular, our collective consciousness.
According to the Mayan Calendar December 21, 2012 marks the beginning of a new era in the development of man. It marks a transition from where mankind has a consciousness, to a higher level where mankind is consciousness.

"According to the Maya’s predictions the physical unleashing cause for the change is that we would receive a radiation originated in the centre of the galaxy which would be transmitted to the Solar System as an immense “radiant flare”. This event would start a new cosmic cycle. "
The above is a quote from Marilola Castro Moure, a reporter from The Digital Magazine of Cuban Arts and Culture. In my opinion this just conjecture on her part since it bears no scientific fact, just assumptions.
Interestingly enough, for all the talk about 2012, it is quite difficult to find a single listing of all the prophecies. Most of what you find on the Internet is vague–generalizations of mass destruction or a transformation into a new age.
Therefore interpretation as to whether 2012 will bring total destruction or a transformation of our world is pure conjecture.
Below are prophecies (not necessarily Mayan) for 2012:
1. There have been three or four previous races and ages of humanity (depending upon the source you read). All of these have been destroyed in major cataclysms. December 21.2012 marks the end of this age and it will end in major catastrophes such as Earthquakes. (see commentary on this statement below)
2. For half of the katun (20 year Mayan cycle) there will be food, for half some misfortunes. This katun brings the end of the "word of God." It is a time of uniting for a cause.
3. As we pass through transition there is a colossal, global convergence of environmental destruction, social chaos, war and ongoing Earth changes.
4. The Earth will undergo a magnetic field shift, reversing the polarity of the planet.
5. An asteroid or comet will collide with the Earth.
Which of these, if any will, cause the paradigm shift is unknown.
So, to answer y our question, no, the Mayans did not predict exactly what would happen.
