This all depends on which canon you choose to follow. It's said to have been a hurricane, known as Clarissa, which struck sometime between three and six months following the events on Jurassic Park. Honestly, I think InGen would have had some precautions in the events of extreme weather, since they chose the Pacific as their playground. So, most likely a combination of events would've occured to force InGen to close down her last facilites on Sorna, Muerta, and possibly the Azores and Marianas if you count Jurassic Parks Japan and Europe as canon from the movie.

In the case of the movies, the hurricane would only be the background for the closure. Critical systems failures during the storm would've forced them to evacuate, and by the time the storm passed, InGen would've been in too much debt to resurrect another attempt at a park.

In the novels, Hammond died during the Nublar Incident, and than the hurricane hit the islands. New management declared InGen bankrupt, and sold all of its property to the American public.
