Krias Yam Suf was far more
dramatic and miraculous than a simple splitting of the sea. The Mishna
in Pirkei Avos (5:4) says that 10 miracles happened to Bnei Yisroel
during Krias Yam Suf. The Bartenura lists them. The Mei'am Loez counts 50 main nissim that happened to Bnei Yisroel
from when they left Mitzrayim until after Krias Yam Suf. He actually
divides them into different parts for a count of more than 150. To see list of these 50 nissim click here.
