A common misconception is that Buddhists do not believe in hell. While this may be true of some Buddhists, the Buddha offered specific teachings about hell.
In “Devaduta Sutta”, the 130th discourse of the Majjhima Nikaya, Buddha teaches about the hell in vivid detail. Buddhism teaches that there are five (sometimes six) realms of rebirth, which can then be further subdivided into degrees of agony or pleasure. Of these realms, the hell realms, or Naraka, is the lowest realm of rebirth. Of the hell realms, the worst is Avīci or “endless suffering”. The Buddha’s disciple, Devadatta, who tried to kill the Buddha on three occasions, as well as create a schism in the monastic order, is said to have been reborn in the Avici Hell.
However, like all realms of rebirth, rebirth in the Hell realms is not permanent, though suffering can persist for eons before being reborn again. . . . Buddhism teaches to escape the endless migration of rebirths (both positive and negative) through the attainment of Nirvana.[i]
The Narakas of Buddhism are closely related to diyu, the hell in Chinese mythology. A Naraka differs from the hells of Abrahamic religions in two respects: firstly, beings are not sent to Naraka as the result of a divine judgment and punishment; secondly, the length of a being’s stay in a Naraka is not eternal, though it is usually very long.
A being is born into a Naraka as a direct result of his or her accumulated karma and resides there for a finite period of time until that karma has achieved its full result. After his or her karma is used up, he or she will be reborn in one of the higher worlds as the result of karma that had not yet ripened. . . . Physically, Narakas are thought of as a series of cavernous layers which extend below Jambudvīpa (the ordinary human world) into the earth. There are several schemes for enumerating these Narakas and describing their torments.[ii]

In Dante’s Inferno, he detailed his belief in nine distinct different levels of hell (see image below).[i]
Conservative Christians beliefs about hell are well summarized in this excerpt from the Baker Encyclopedia of the Bible.
While the duration of punishment in hell is eternal for all who have chosen that destiny for themselves, there are degrees of punishment proportional to the degrees of guilt of each individual. Only God is able to determine what those degrees are, and he will assign the consequences with perfect justice according to the responsibility of each one. Evidence of such gradations in future punishment is found in Scripture (Mt 11:20-24, Lk 12:47-48, Rv 20:12,13; cf. Ez 16:48-61). An obvious comparison is made in these texts between the differing intensities of punishment that are involved in the contrasting privileges, knowledge, and opportunities.[i]
The Buddha taught in his First Noble Truth that “life is suffering”. His view of life on earth seems similar to Dante’s portrayal of the First or Second levels of hell.
