Wow.... A drop in the level of the land by 4 feet explains why the tsunami's overcame the 20+ feet sea walls so easily...

“Geospatial Information Authority”

That sounds odd. Sounds like an authority invented in the last week? Since the Japanese are feeling like their government is not in control?

I wonder how this would affect property lines.

Stunning.
Has any quake in recorded history resulted in such a massive land shift?

From the photos, I’ve wondered how much of that land will ever be recovered from the sea.

The article is nor understandable without a map or photos

Here's a map.

More data

Record land mass movement has been observed in Miyagi. Quake-hit Oshika Peninsula moved 5.3 meters and dropped 1.2 meters according to Geospatial Information Authority. Goverment showed both records data on Saturday. Geospatial Information Authority based in Tsukuba issued a report that says that peninsula on the Pacific coast moved in East-SouthEast direction toward the quake epicenter. Earthquake also triggered land mass movements in many areas ranging from northeastern region of Tohoku to the Kanto region including Tokyo. In Iwate prefecture, a point in Yamada (north of Miyagi) moved 25cm to the east, while a point in Chiba’s Choshi, south of Miyagi, moved 17 cm to the east. Postseismic Slip Distribution Model by Geospatial Information Authority of Japan constructed a postseismic slip distribution model using surface displacement data observed by the GPS Earth Observation Network System (GEONET) for the 2011 off the Pacific coast of Tohoku Earthquake. You can visit this page for more data and charts. Eastward displacements are observed along the Pacific coast from Aomori Prefecture to Chiba Prefecture. The observed postseismic displacement partly includes crustal deformation due to aftershocks. A postseismic slip expands in and around the inferred coseismic slip area . In particular, relative large slips are estimated in the northwest and in the south (off Choshi) of the coseismic slip area.

For me, this helps. The quake was apparently off shore of the area in question

This is the best I found to help me understand the movement. It is from the Geospatial Information Authority Japan

No doubt the Global Warmists will use this as proof that the oceans are rising.
