Feared Nankai Trough quake could cause 50 trillion yen in economic damage: expert
Japan would suffer economic damage worth up to 50 trillion yen if a massive earthquake occurs in the Nankai Trough in the seabed off central to western Japan, an expert’s estimate has shown.
The feared Nankai Trough quake is expected to directly hit Japan’s pacific belt zone, especially areas spanning from the Chubu to Kinki regions, where the headquarters and main plants of major auto and electric appliance manufacturers are concentrated. If the Tomei Expressway and other main arteries running through the region are cut off, the suspension of distribution and supply chains would also cause tremendous economic damage.
“It wouldn’t be surprising if direct damage (to housing, production equipment and social infrastructure) amounted to about 40 trillion to 50 trillion yen,” said Motohiro Sato, professor at Hitotsubashi University’s graduate school.

Gov’t stresses need for anti-disaster steps to cope with possible Nankai Trough quake
While releasing a shocking prediction that up to 323,000 people could be killed in the event of a magnitude 9-class earthquake with its focus in the Nankai Trough off central and western parts of Japan, the government stressed the need to speed up efforts to implement anti-disaster measures across the country to minimize the impact of major disasters.
When the government released a prediction in late March this year that a Nankai Trough earthquake could trigger tsunami of up to 34.4 meters, people in some quarters were caught off guard and hopelessly thought that they would not be able to deal with the onslaught of such a huge disaster. Therefore, the government tried to have people respond to the latest prediction by showing how far quake-resistant measures and early evacuation could help reduce potential damage and casualties and by stressing the need to speed up efforts to implement conventional anti-disaster measures.

The amount of treated water being constantly injected into the Reactor Pressure Vessels of Reactors 1, 2 and 3 has fluctuated often for no reason that TEPCO cares to identify, but on August 30 that amount temporarily dropped below the levels specified by the NISA’s safety regulations.
Cause is still unknown, but unlike in the past, TEPCO’s Matsumoto says the company will conduct investigation to identify the cause.
If you want to check the temperature readings of the RPVs, here’s TEPCO’s page(English).

Underground cesium near Fukushima reactors increases the deeper samples get — Other locations tested are much different, with higher radioactivity on top
Title: Nuclide Analysis Results of Marine Soil – Inside the Port Entrance of Fukushima Daiichi Nuclear Power Plant
Tested: July 23, 2012
Published: August 30, 2012
At sample points furthest from the reactors, cesium levels drop rapidly as the samples deepen:
① (0～10cm) Cs-134 @ 19,000 Bq/kg; Cs-137 @ 29,000 Bq/kg
① (10～20cm) Cs-134 @ ND Bq/kg; Cs-137 @ ND Bq/kg
① (20～30cm) Cs-134 @ ND Bq/kg; Cs-137 @ ND Bq/kg
③ (0～10cm) Cs-134 @ 360,000 Bq/kg; Cs-137 @ 540,000 Bq/kg
③ (10～20cm) Cs-134 @ 80 Bq/kg; Cs-137 @ 140 Bq/kg
③ (20～30cm) Cs-134 @ 77 Bq/kg; Cs-137 @ 110 Bq/kg
④ (0～10cm) Cs-134 @ 5,300 Bq/kg; Cs-137 @ 8,100 Bq/kg
④ (10～20cm) Cs-134 @ 120 Bq/kg; Cs-137 @ 200 Bq/kg
④ (20～30cm) Cs-134 @ 37 Bq/kg; Cs-137 @ ND Bq/kg
At sample points nearest the reactors, cesium levels do not drop rapidly. At location 6, the levels rise:
② (0～10cm) Cs-134 @ 29,000 Bq/kg; Cs-137 @ 44,000 Bq/kg
② (10～20cm)Cs-134 @ 7,500 Bq/kg; Cs-137 @ 12,000 Bq/kg
② (20～30cm) Cs-134 @ 24,000 Bq/kg; Cs-137 @ 39,000 Bq/kg
⑥ (0～10cm) Cs-134 @ 70,000 Bq/kg; Cs-137 @ 110,000 Bq/kg
⑥ (10～20cm) Cs-134 @ 73,000 Bq/kg; Cs-137 @ 110,000 Bq/kg
⑥ (20～30cm) Cs-134 @ 130,000 Bq/kg; Cs-137 @ 190,000 Bq/kg
Location 2 is nearest Reactor 1, and Location 6 is nearest Reactors 2, 3, and 4.
