So the information was given in the image below which can be found in Volume 17. 鳴柱 is the kanji that's used which roughly translates to Roaring Hashira whereas 雷柱 would translate to Thunder/Lightning Hashira etc. Technically it's not the official translation, but it is considered correct. When the ViZ translation comes out, and they use Thunder then we would just change it to Thunder but until then, Roaring is the most correct.
