The risks, timing and possible warning signs of an extreme gama ray burst and cosmic ray spike from the galactic core of our Milky Way galaxy, resulting from what's called the "G2 cloud" now approaching it, are becoming increasingly well understood.

New Developments on the G2 Cloud Journey
Paul LaViolette
There have been new developments in the story on the G2 Cloud. Recent observations of the G2 cloud made in the near infrared at the Keck Observatory indicate that the cloud will reach its closest approach to the Galactic center around mid March of 2014 instead of June of this year (2013). Also the new findings indicate that G2′s orbit will take the cloud twice as close to the GC than previously thought. The distance of closest approach is now predicted to be 130 AU rather than 266 AU, as previously thought. If the star embedded in the G2 cloud is a binary system or contains a single star with orbiting planets, there is the danger that the Galactic core may tidally strip away the lower mass companion star or one or more companion planets at the time the stellar system is at orbital pericenter closest to the core. In that case the consequences could be catastrophic. For example, if an entire 100 jupiter mass brown dwarf were to plunge into the Galactic core in one sudden event, it is almost certain that it could jump-start the core into an active Seyfert state and generate a potentially lethal superwave.
This could turn out to be an instance of a Galactic Superwave that LaViolette has been researching for decades.

Recent observations of the G2 cloud made in the near infrared at the Keck Observatory indicate that the G2 cloud will reach its closest approach to the Galactic center around mid March of 2014 instead of June of this year. In their paper preprint, astronomers Phifer, et al. (http://arxiv.org/abs/1304.5280) place the date of the G2 cloud’s closest encounter with the Galactic core at somewhere between the end of January 2014 and the beginning of May 2014 with a median date of mid March. Moreover they estimate that G2′s orbit will take the cloud twice as close to the GC than previously thought. The distance of closest approach is now predicted to be 130 astronomical units (http://en.wikipedia.org/wiki/Astronomical_unit) (AU) rather than 266 AU, as previously thought. See Astrobites Synopsis (http://astrobites.org/2013/04/25/the-infamous-galactic-center-source-g2-gas-cloud-or-star/).
The revised trajectory for the G2 cloud dramatically increases the chances that a star hidden within the cloud might have companion stars or planets ripped from it by tidal forces and ultimately consumed by the core. Since tidal force varies as the inverse cube of distance from a massive celestial body, this means that the G2 cloud will be subjected to tidal forces 8.5 times greater than previously estimated. Also since the radiation flux from the Galactic core varies as the inverse square of radial distance, the G2 cloud and its hidden star will be subject to a cosmic ray energy flux and galactic wind energy flux 4 times greater than previously supposed. Another factor disrupting an embedded star or planet is the celestial body’s internal genic energy flux which depends on the value of the ambient gravity potential. If the G2 cloud is to approach twice as close to our Galaxy’s supermassive core as had been previously thought, this will cause the genic energy output of embedded planets or stars at pericenter to be twice as large as had previously been estimated. (More will be said about these mechanisms below.)
In a Starburst Foundation forum posting made last October (http://starburstfound.org/superwaveblog/?p=246), I had presented the possibility that the G2 cloud may harbor a jovian planet or brown dwarf, an idea that had also been suggested by Murray-Clay and Loeb. They proposed that the G2 cloud may contain an unseen low-mass star that is surrounded by a dust and debris accretion disc and that the material in this accretion disc has been evaporated to produce the enveloping G2 cloud as a result of exposure to ionizing radiation or because the accretion disc had been tidally disrupted by previous orbital encounters with the Galactic core. The idea I proposed agrees with their idea of a low mass star or brown dwarf being present. But I believe that the G2 cloud was generated because the contained star or planet has been expelling its atmosphere due to an enormous amount of internal heating it is currently undergoing. Although some of the generated G2 nebula could have come from evaporation of a disc of material orbiting the star, I believe that the main contributor is the atmosphere of the embedded star or planet.
...
The real cause of the generation of the G2 cloud is the star’s entry into the unique Galactic core environment and the consequent stellar heating that occurs there. It has nothing to do with the star accreting a disc of debris that it may have transported with it on its inward journey.
The T Tauri star idea that these astronomers have proposed in many respects resembles what I had suggested in my forum posting last October. I had proposed that the G2 cloud may contain a brown dwarf having a mass of 50 Jupiter masses which has inflate to as much as 3 times the diameter of the Sun and is undergoing a high rate of mass loss as a result of the internal heating. As I explained in my earlier posting, a star approaching the Galactic core would behave as a T Tauri star would be radially expanded, overluminous, and outgassing its atmosphere to generate the surrounding G2 cloud because of the enormous amount of genic energy it would be producing internally and because of the large cosmic ray flux it would be intercepting from the GC. In fact, in my opinion, any star approaching close to the GC would be expected to outgas and generate a compact ionized gas cloud similar to the G2 cloud. Of course, the genic energy concept is not widely known in mainstream science in spite of its predictive success (http://etheric.com/the-pioneer-maser-signal-anomaly-possible-confirmation-of-spontaneous-photon-blueshifting/). But, knowledge of this mechanism makes all the difference in being able to understand what is currently transpiring within the G2 cloud, and what will continue to transpire as the G2 cloud approaches pericenter in March 2014.
...
Now, with the recent prediction that the G2 cloud should actually approach to within 130 AU of the core, we see that the cloud’s diameter is about as large as its closest distance of approach to the core. In the model of Scoville and Burkert, there is a 100% certainty that the cloud will become accreted onto the Galactic core. They find that all gas in the G2 cloud that is lies more than 1 to 3 AU from the star will be tidally stripped away, resulting in an accretion of up to 0.1 earth masses onto the Galactic core.
I predict that the energy output and mass loss rate of the embedded star will rise substantially in the next 10 months as the G2 cloud approaches its orbital pericenter and will result in far greater accretion onto the core than predicted by Skoville and Burkert. The total gas accretion onto the core may perhaps be as great as half an earth mass. However, this alone would produce at most a 50% average rise in the energy output from the core (Sgr A*) over perhaps several months time. As mentioned in my earlier posting, in 2001 the core was observed to produce a much larger magnitude increase in energy flux of about 3 fold over a period of one hour without any serious consequence to the Earth.
The real danger is if the G2 cloud contains not one star, but two. That is, there is the possibility that the cloud may harbor a close binary star system consisting of a primary star orbited by a lesser massive companion star or of a star orbitted by one or more jovian planets. Current observations cannot exclude this possibility since dust obscuration prevents us from peering very deep into the G2 cloud. This binary star/planetary system scenario would look something like that seen in the video below. The dust and gas being dispersed to form the G2 cloud would be coming not only from a possible planetary disc around the star, but also from the central star itself and from any planets that may be orbiting it since planets would be actively expelling their atmospheres as well.
...
It is known that a very high percentage of stars in our Galaxy are either binary star systems or are single stars orbited by jovian planets. Hence there is a high probability that the G2 cloud may harbor such a multi-body system. If this is the case, there is the danger that the Galactic core may tidally strip away and consume the system’s lower-mass companion star or one or more of the star’s planets at the time of pericenter passage of the core. For example, a one solar mass star similar to the Sun would have a tidal radius of 0.5 to 1 AU at its orbital pericenter which means that any stellar companions, planets, or debris orbiting at radii greater than this could be tidally stripped away from their orbit about the primary star and ultimately be pulled into the galactic core.
In the case where an entire 100 jupiter mass brown dwarf were to plunge into the Galactic core in one discrete event, the energy release would be equivalent to that released in a hypernova, the most powerful of known supernova exposions (~1053 ergs). This could be enough to jump-start the Galactic core into a Seyfert state and generate a potentially lethal superwave. If this amount of energy were delivered within the space of one day, this would release energy at the rate of 1048 erg per second, giving a luminosity one hundred thousand times greater than the cosmic ray luminosity estimated to currently be coming from Sgr A* (based on my estimate of 1043 ergs/s — see Subquantum Kinetics (http://etheric.com/subquantum-kinetics-4th-edition/)), and equivalent to the luminosity radiated by the active core in a Seyfert galaxy.
We will know if such a scenario is going to occur by closely monitoring the G2 cloud. As the cloud nears pericenter, if we see it appear to divide and spawn off a subcloud that begins rapidly accelerating directly toward the Galactic core, we will know this worst case scenario is about to occur. This subcloud will contain within it the binary companion star or jovian planet that has been tidally stripped off from the parent star. At this point we will have about two months before its inevitable impact on the core, at which point an exceedingly bright gamma ray burst and cosmic ray spike will be detected on Earth, far greater than any we have seen until now. The superwave will have arrived at our doorstep, possibly heralded by earthquakes occurring a few days before.========
There is more, including computer simulations, at G2 Cloud Predicted to Approach Twice as Close to GC (http://etheric.com/g2-cloud-predicted-to-approach-twice-as-close-to-gc/).
Perhaps this is why the underground cities are being prepared. The science now seems sufficiently well understood to provide adequate warning to move all the "chosen" people into these underground bases for the most dangerous period.
If there is faster-than-light communications, then we (well, some select humans) may have already been warned. If such a supernova explosion did occur, it occurred some 24,000 years ago ... and we're just waiting for the light speed energy to reach us with the news.
