No it's not. The pool predicted hashrate from block explorers is based on average block solve frequency - if a pool has a period of luck, its hashrate appears higher. In this case solo's luck has been very good for the last 5 blocks so it grossly exaggerated there. The correct current pool hashrate is what you see on the pool itself, and is around 30PH, which is still a lot higher than it's been for the last few years as a result of the recent publicity. It's impossible to know if this hashrate will be maintained, but it's my guess the next unlucky block will have many miners leaving when they don't get any rewards, and the hashrate will slowly peter out back to its original ~5PH baseline.
