Yikes. Looks like a fair amount of damage...

Apparently, some homes/buildings collapsed. With a M7.5, I'd expect a lot of damage near the epicenter, which was on land, as were the majority of aftershocks.

Anamizu is a town located in Hōsu District, Ishikawa Prefecture, Japan, on the Noto Peninsula.

Space photos show Japan's 7.6-magnitude earthquake lifted land out of the sea, extending parts of its coastline by as much as 2 football fields

• The quake raised land along the coast, extending the coastline by up to [250 m, or] 820 feet, in some places

In other words, the seashore (beaches) are extended further outward. Navigation charts would seemingly need updating.

Preliminary satellite analysis and on-the-ground surveys have found that the earthquake raised land along the coast — a process called uplift — by as much as 4 meters, roughly 13 feet.

Some media are reporting M7.6 vs M7.5.
