Needed: information about post disaster gender based violence in Tohoku

I've been asked about "unconfirmed" reports of women who have been sexually assaulted in shelters recently.  Someone asked if personal alarms could be distributed to help women in centers.

Although this is very common in post disaster situations i have yet to see any data or programs addressing these issues.

If anyone out there has information on this issue and or knows who is providing support - please drop me a note. if you can introduce people who might know more that would also be helpful

Please let me know what infromation can/cannot be shared publically.
