What is the "landfall" of a typhoon? (FAQ for Typhoon)

The "landfall" of a typhoon means the typhoon's center moves ashore from the ocean, which always causes severe disaster for the landfall area as the strongest winds occur in the vicinity of the typhoon's center no matter how large the typhoon's storm area is - even with over hundreds of kilometers in storm radius.
