- This article is about the event known as the Shattering. For the patch titled "The Shattering", see Patch 4.0.3a. For the book, see The Shattering: Prelude to Cataclysm.
The Shattering (also called the Second Sundering and Cataclysm) was a worldwide disaster that struck Azeroth following Deathwing blasting his way from Deepholm into the world. Earthquakes, volcano eruptions, and floods followed in his wake, reshaping the face of the world.
For the players, The Shattering was introduced on November 23, 2010 with Patch 4.0.3a.

The coastlines of Kalimdor and the Eastern Kingdoms shifted, flooding some old lands and exposing new ones. Whole parts of the world, like Thousand Needles and a large chunk of Tanaris, ended up underwater. In some cases, tidal waves caused by the Shattering flooded or destroyed coastal settlements like Auberdine, Rut'theran Village, and Feathermoon Stronghold, forcing their residents to relocate — usually inland. Even far from the coast, fires, avalanches and lava eruptions changed some areas beyond recognition.
The tectonic shifts blocked some old routes, like the one between Badlands and Loch Modan, and opened some new ones through previously impassable mountains. The Shattering also damaged an ancient titan device previously hiding the Uldum complex, exposing access to it from Tanaris.
The Shattering brought the Elemental Plane closer to Azeroth, bringing the world in direct conflict with the elemental lords — including Ragnaros, who, upon his return, assaulted Nordrassil, prompting Malfurion Stormrage to organize a defense of Mount Hyjal again.
The goblin island of Kezan and the self-isolated nation of Gilneas suffered greatly from natural disasters, leading directly to events that affected the existing balance between the Alliance and the Horde, redrawing the political map of the world. Mount Kajaro on Kezan erupted, forcing an evacuation by the goblins. Earthquakes damaged the Greymane Wall that had protected Gilneas, opening them up to invasion by the Forsaken and the rest of the Horde.
