Generally: No. The 100 hour moving widow correlation fluctuates around 0, so there is no clear direct correlation.

However we can note, that liquidations remain in the sub 1M USD range for most of the time, but spike to 10-50B USD for very single brief moments. These violent storms of liquidation almost always happen after (at the end of) a drop in the LUNA price, however they are almost never followed by a further drop. This would suggest that there is a price stabilising mechanism in play (ie. the liquidated stablecoins getting reinvested in LUNA) as one would otherwise expect downward pressure on the price.
