In order to discuss the potential impact of solar “superflares” on space weather, we investigated statistical relations among energetic proton peak flux with energy higher than 10 MeV (Fp), CME speed near the Sun (VCME) obtained by Solar and Heliospheric Observatory/LASCO coronagraph, and flare soft X-ray peak flux in the 1–8 Å band (FSXR) during 110 major solar proton events recorded from 1996 to 2014. The linear regression fit results in the scaling relations , , and with α = 0.30 ± 0.04, β = 1.19 ± 0.08, and γ = 4.35 ± 0.50, respectively. On the basis of simple physical assumptions, on the other hand, we derive scaling relations expressing CME mass (MCME), CME speed, and energetic proton flux in terms of total flare energy (Eflare) as , , and , respectively. We then combine the derived scaling relations with observation and estimated the upper limit of VCME and Fp to be associated with possible solar superflares.
