such that

Hi, What does the "such that " means in the sentences below? and What is the grammar of the sentence ? Please reply in the message bellow. Thank you a lot.

The original sentence:
"So the position of The Pacific Plate 50 million years ago can be determined by moving it "such that" a 50-million-year-old volcano in the hot-spot trail sits at the location of Hawaii today. "

My analysis of the structure of sentence:

..... determined by ( moving)(V) (it such that a 50-million-year-old volcano)(O)( in the hot-spot trail sits at the location of Hawaii today.)(prep)

..... determined by moving it such that (a 50-million-year-old volcano in the hot-spot trail )(S)(sits)(V)( at the location of Hawaii today)(prep).

The reference information:
The oceanic volcanic islands and their hot-spot trails are thus especially useful for geologist because they record the past locations of the plate over a fixed source. They therefore permit the reconstruction of the process of seafloor spreading, and consequently of the geography of continents and of ocean basins in the past. For example, given the current position of the Pacific Plate, Hawaii is above the Pacific Ocean hot spot. So the position of The Pacific Plate 50 million years ago can be determined by moving it""" such that ""a 50-million-year-old volcano in the hot-spot trail sits at the location of Hawaii today. However because the ocean basins really are short-lived features on geologic times scale, reconstruction the world’s geography by backtracking along the hot-spot trail works only for the last 5 percent or so of geologic time.
