Abstract
We present the state of current research of Very Short Gamma Ray Bursts (VSGRBs) from seven GRB detectors. We found that VSGRBs form distinct class of GRBs, which in our opinion, in most cases can originate from the evaporating Primordial Black Holes (PBHs). Arguments supporting our opinion: 1) GRBs with time duration (T<sub>90</sub>) < 100 ms form distinct class: VSGRBs. 2) We observe significant anisotropy in the galactic angular distribution of BATSE VSGRB events. 3) V/Vmax distribution for BATSE VSGRB events indicates the local distance production. 4) VSGBBs have more energetic γ-ray burst than other GRBs with longer duration (KONUS). 5) We observe small number of afterglows in SWIFT VSGRB sample (25%), in contrast with the noticeable afterglow frequency in SGRB sample (78%). 6) Time profile of rising part BATSE VSGRBs is in agreement with the evaporation PBH model.
