From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Second Form Freeza raises his hand and then opens it to release a light gray wave of energy.
Dragon Ball Z
The Death Storm, while easily avoidable, caused large scale planetary destruction and a very large tsunami that traveled for a large distance in all directions. The island on which the attack was performed exploded, leaving only a small island on which Second Form Freeza stood on.
Second Form Freeza used this attack in his fight against Son Gohan, Kuririn, Dende, and Vegeta. They were all knocked back and thrown into the air. They managed to survive, however, Kuririn was slightly injured.
It is named Sonikku Bomu (ソニック ボム, Sonikku Bomu) in Dragon Ball Z: Sūpā Gokū Den: Kakusei Hen.
