Disaster - Adventure!

Though, I have not come across a "fan blog" for this type of novel, I found some titles that would probably work.

James Rollins - Deep Fathom has an ex Navy SEAL who surfaces to find the world on fire, because of some horrible solar flares that are causing no end of trouble.   It seems that there is more to the story, including an ancient civilization, but it appears that the flares, the burning and the earthquakes would probably appeal to someone who wants high adventure and people in peril, plus a strong hero to save the day.

Now, Stephen Coonts is more military action, but in Deep Black: Death Wave  there is definitely a threat of a disaster,  as a fault line is compromised, and there  is a plan to set off a landslide that will activate the fault line and create giant waves that may wipe out a lot of cities.    So, I would put this definitely in the "threat of disaster" category and think that I could convince  a reader to try it.   It does look like it also has an engaging adventure hero working to prevent the disaster from happening. 

The third will by by old adventure standby, Clive Cussler.
I found one called Zero Hour,  and apparently, there is a new energy source called zero point energy,  but perhaps harnessing it is not a good idea, as it weakens the Teutonic plates and will probably cause massive earthquakes that will destroy the planet.   So, in order to prevent this from happening, an underwater team of specialists need to head deep into the depths of the ocean and find these energy creating devices before it is too late.  This also falls more into the "preventing a disaster" category, but I think would be enjoyable for readers who like a lot of action and adventure with a disaster theme.
