The website -- http://familylinks.icrc.org/nepal-earthquake/ -- can help register names of those who wish to inform that they are alive and also those with whom they have lost contact.

It has been launched in both English and Nepali.

"This website makes it possible to search through the list of missing persons and of those people who have responded that they are alive, register names of persons who wish to inform others that they are alive and names of those with whom they have lost contact," the ICRC said in a statement.
