This means that $72,200 worth of short positions bets that the price of Cardano’s $ADA token would fall were liquidated closed out automatically when ADA's price reached $0.430. When the price goes up and hits a certain level short positions face losses and if they don’t have enough funds to cover those losses they get liquidated.
In this case the price increase to $0.430 likely surprised short-sellers leading to these liquidations.
