During the events of Blackest Night, Calypso's bond with the Earth became significantly stronger.  The moment she was to be drafted into the Black Lantern Corps, the Earth rejected the essence of the Black Lanterns from Calypso and revived her as the new Earth Elemental.  As the new Earth Elemental, Calypso gained a significant increase in her existing powers as well as the introduction of newer abilities.  Her already superhuman strength is heightened to Class 100+, and her enhanced durability allows her greater resistance to blunt force attacks.  She is comparable to Wonder Woman in these aspects.  Her terrakinetic abilities are magnified to a massive scale, of which the upper limit is unknown.  A new ability Calypso possesses is the ability to speak with the Earth.  By doing this, she can locate and track down people and objects as long as they are nearby the Earth's surface.

Her bond with the Earth grants Calypso with another unique ability.  Although she possesses no psychic powers, Calypso's mind is heavily secured against psychic forces as long as she is standing firmly on the ground.  Like with almost all of her powers, however, this psychic resistance weakens the farther away from the Earth's surface she is.  Calypso still cannot survive outside of the Earth, and she will die if she ever leaves the Earth's atmosphere.  She can be revived, no matter what state her body is in, as long as her remains are buried within the Earth.  Calypso's powers can increase as she travels into the Earth's crust, further adding to the mystery of where her true upper limit lies.

In listed form, Calypso's powers are as follows:

Terrakinesis
Earth Bond
Earth Communication
Superhuman Strength: Class 100+
Superhuman Durability
Psychic Resistance

The level of her powers, except for the terrakinesis, change depending on how close to the Earth's core she is.  When her feet are planted on the ground, she's equal to Wonder Woman in strength and durability, and her mind is impossible to breach.  The farther she gets away, the weaker she becomes.
