And though studies into radon changes have already yielded good preliminary results, the method suffers from the same problems as the other approaches-there's still no way to precisely predict the quake's epicenter, magnitude, intensity, and potential for damage.
雖然以氡氣濃度變化觀測是否發生地震已有初步成果，不過它也和其他前兆研究一樣，尚無法預測地震發生的震央、規模、震度及實際破壞程度等。
