Sites

Site RK1 Sakawara City (now called Katori-Shi) . Central District. See Koseki report from JGS 0319

Site RK2: Banks of Tone River, liquefaction of river soil and incipient failure of wide section of levee bank. All along the Tone River border to levee is ample evidence of soil liquefaction on baseball fields, tennis, soccer fields and other park facilities along the river's edge.

Site RK3: YokoTone {lateral to Tone river.) Lateral spread embankment failure and liquefaction of secondary levee and NTT cell communications tower. Site three along the side channel of the Yokotone River. Extensive liquefaction to ricefields all along the banks of the Yokotone River. House structures have lost roof tiles and in some cases settled and tilted due the liquefaction. Large sand boils, meters to tens of meters across, are along the adjacent ricefields on the bank of the river. A minor secondary levee separating the residential district from the river and a wetland pond has one area (800m) of significant embankment bank failure. 1 m of crest settlement and 2-4 meters of lateral expansion on either side at its maximum. A large heavy generator and communications tower is built on a poorly constructed pad. The tower itself is pile supported it appears to be tilted slightly. The the generator structure and other smallbuilding, and also a house built in the area are tilted as much as 20°. The NTT hour is adjacent to a wetland ponds are one side, a residential district on the other side, at rice field on the third side.

Site RK4: LIDAR SITE JS23, Isobe Lateral Spread. Are site number one at Jon Stewart's JS 23 site this is a lateral spread site along the Isobe area of Tokyo Bay. The lateral spread is described by Stewart. We took our LIDAR measurements from one position on the bridge looking diagonally down at the lateral spread from an excellent location. We took one panorama scan at 0.12 deg. resolution and then we took a high resolution scan from the same position at 0.03 deg. resolution.

Settlement in the residential / commercial district effecting structural foundations. Empty lots have sand boils and minor lateral spreading, ground cracks. Worthwhile SASW site and additional study liquefaction site.

Site RK8: Hinuma lake South Shore . The site is JS7. The site is an embankment failure with base widening and settlement of crest. We scanned the site from two positions at the location with the greatest amount of deformation. Crest crack extend for 800 meters

CEMETARY FOR COLLAPSE RATIO CALC.

Site RK10: This site is the same as JS10 looking at Hitachinaka port. This site has a shallow landslide beneath a large retaining wall that damaged road along the head scarp of the failure. The toe is at the back and side of a port facility building. Four LIDAR scans were taken at the site capturing the heads scarp to toe of this slide. More details can be found in the description JS 10.

Site RK11. Nasukarasiyama Landslide originating from a terrace above a cut bank of a river valley. Terrace areas slope was forested native landscape. the top of the terrace is the tree farm creast scarp is approximately 250 m wide 150 m long and perhaps with an average depth of 2 m of material: total volume estimated at ~70,000 m ^3.

Site RK13. Shirawkawa Village landslide. This is a large landslide and we collected three LIDAR scans on April 5. This landslide came down a slope of volcanic ash or pumice (?). Samples are lightweight and white and color, or oxidized brown. The landslide came off of the forest slope onto an agricultural village impacting several houses, covering and crossing of the narrow valley. The location is marked in the GPS log as site 13.

Site RK15: Fujiwara dam failure

Site RK27 (SASW site 79ISHI). The site liquefied during the aftershock of April 7. ISHINOMAKI bay hard hit by the tsunami and evidence of liquefaction from the main event are completely obscured by the tsunami damage. At the Ichinomaki oil refinery and tank storage facility adjacent to SASW site 79 had interesting geotechnical damage in the form of scoured soil has a bouyant tank that was floated off at the base pad and out of the storage yard. Evidence of significant scour of soil from the piers supporting the port structures

Agricultural embankment failure

Minor liquefaction feature at embankment

Site RK41: Minamisanriku in some cases 15 m high debris seen on the fourth floor level and rooftops of buildings. However the area has no landslides or other geotechnical aspects other than tsunami damage.

Site RK42 MinamiSanriku no structural damage nor visible geotechnical damage. tsunami damage timpact to o about 30% of the community.

Site RK43: Kessenuma bridge-deck closest to harbor was swept off the piers and scattered hundreds of meters inland. Piers are scoured but in place. the bridge was built in 1932.

Site RK44: Kessenuma Highway overpass northeastern part of town was completely swept off piers. Piers remain in place with significant scour at their base. the bridge through-truss was thrown inland about 100 m from the bridge

Site RK45: Ofunato town, northern section that we drove through was largely unscathed by the tsunami. The port district has significant damage but most of the northern residential and commercial districts we drove through were normal with undamaged housing. No flooding and no debris. This was a welcome sight after what we've seen the last several days.
Aside from the tsunami damage so far from the border of Miyagi to the north coast of Iwate there appears to be no road damage, landslide, liquefaction, or noteworthy structural problems other than those directly related to or impacted by the tsunami.

Site RK46 Otsuchi town - very bad tsunami inundation but no apparent landslides or shaking-related structural damage.

Site RK47 Yamada-machi Miyako Town, Iwate Prefecture. Photograph of overturned tsunami seawall with meter stick from tsunami research team. In the central part of the city there was a fire after the tsunami and an unknown number of blocks of buildings were burnt.

Site RK48 Port of Miyako. No evidence of geotechnical damage to the port. Only damage from the tsunami. the tsunami height looks to be approximately 6-7 m in height.

NODA Town. Tsunami damage but no geotechnical damage at the low elevations of the city. Talked with recent Prime Minister HATOYAMA Yukio about GEER and USGS activities and our collaborations with PARI, Toko University and Kobe University in earthquake geotechnical engineering research.

Site RK51 tsunami deposits and debris scattered in a field adjacent to beach north of Hachinohe on the Oma peninsula coast. Oma Peninsula. tsunami runup diminishing heights.

Site RK52: Monomisaki port has no tsunami damage. First town in 400 miles without impacts.

Site RK53: Oma town. No damage along entire coastline from Monomisaki to Oma.

Site RK54 AOMORI STATION, site of repeat liquefation from 68, 81, 93 had no liquefaction from the March 11, 2011 event.
