Earth Release: Hiding Like a Mole Technique* (土遁・土竜隠れの術, Doton: Moguragakure no Jutsu)
Ninjutsu, C-rank, Supplementary
Deidara, Tobi

Moving freely while being hidden underground
That is this escape technique's main point!!

←By sensing the magnetic force, the user can pinpoint where they are, despite being underground.

Thus technique changes earth into fine sand by flowing chakra through it, allowing the user to dig through it like a mole. While underground, one can sense what is happening on the surface and use that information to launch a surprise attack on the enemy. One can also hide deep in the ground, escaping to a depth where the enemy can't reach.

*The kanji of "mogura" literally mean "earth dragon". Yes, the Japanese decided to call their moles earth dragons**. I love this language more with every minute.
**It probably comes from the verb moguru (潜る, "to dive," "to get in," "to go underground"), though, but why let etymology stand in the way of a bad-ass name?

With the mind's eye, sense those yonder and survey a thousand ri

Because Karin has excellent perception abilities, it is possible for her to use this enemy-searching technique across an extremely vast range. By closing her eyes and opening her mind's eye, she can perceive abnormal chakra activity within a radius of dozens of kilometres. Also, if she has a specific chakra in mind, she can perceive its location and movements in minute detail.

[Karin sensing Team Snake's pursuers]
←She accurately grasps as much as her target's numbers, characteristics and speed of movement.

¹ Kagura (神楽, divine entertainment) is a type of Japanese theatrical dance, considered to have been developed by the goddess Ame-no-Uzume. Its roots lie in certain kinds of divination and pacification of the spirits.
² A "ri" (里) is an old unit of distance. It used to be about half a kilometre (and still is in China, where it is called a "li"), but elongated over time until it was fixed on 3927,27 metres during the Meiji period. A thousand ri is used as a general measurement for a very long distance. There's a famous Chinese by Laozi saying that goes "a journey of a thousand li begins with a single step" (千里之行，始于足下, Qiān lǐ zhī háng, shǐ yú zú xià).
