Japan earthquake damage - CATDAT did come up with a reliable estimate only 90 minutes after the earthquake

The extensive damage to housing, roads, utilities and businesses across seven prefectures (states) has resulted in losses of between 16 trillion yen ($198 billion) and 25 trillion yen ($309 billion), according to a Cabinet Office estimate today. This is the first estimate from the Japanese government to includee total loss estimates. The government™s estimate is in line with the World Bank™s estimate of $122 billion to $235 billion in damages.

This makes the CATDAT estimate of between $100-$500 billion, less than 90 minutes after the earthquake, reasonable.
The unknown limit is the level of indirect losses stemming from business interruption and consumer confidence.

This would also make it more costly than the 1923 Great Kanto earthquake (equivalent to around $215 billion USD in 2011 dollars) (as stated as of 07:11 UTC, after the earthquake). The 1995 Kobe earthquake caused $142 billion USD (2011 dollars). The second highest loss ever came from the 2008 Sichuan earthquake in China caused $151 billion USD (2011 dollars).

Electronics and semiconductors
Estimates of loss to PCB (Printed Circuit Boards) = $1.8 billion (calculated as a percentage of GDP).
In terms of silicon chips the loss will not be so much = $125 million.
"Manufacturing operations have stopped at Shin-Etsu Chemical Co. Ltd.™s Shirakawa facility.  MEMC Electronic Materials Inc. also stopped manufacturing at its Utsunomiya plant. Together, these two facilities account for 25% of the global supply of silicon wafer used to make semiconductors"

"In another development for the global electronics supply chain, two Japanese companies announced they have stropped production that amounts to 70% of the worldwide supply of the main raw material used to make PCBs. PCBs are used in all electronic products, from PCs to smart phones, to digital wristwatches.
The companies, Mitsubishi Gas Chemical Company Inc. and Hitachi Kasei Polymer Co. Ltd., said they will resume production within two weeks of the raw material called copper-clad laminate (CCL)."
