While this tragedy is often referenced by opponents of LNG, it was an important learning lesson for the industry who adopted stringent safety codes afterwards to prevent this type of accident from ever occurring again. Containment dikes are designed better and are engineered to hold the entire volume that is stored in tanks. Material choices are much more stringent. And most importantly, LNG storage tanks are not located in areas where spills will threaten local communities. Storage tanks leaking into sewers presents a worst case scenario where the vapor is contained and not allowed to dissipate.
