locate missing friends and family in Christchurch following the terrible earthquake. In every disaster, those on the outside all worry about our loved ones and those within all want to assuage the worries of their friends away.Person Finder: Christchurch Earthquake, February 2011.twitter has been advertising this and many other messages to help the people of christchurch.Today's 6.3-magnitude earthquake that ravaged Christchurch prompted many stars to take their Twitters to send their condolences to all those affected. Many international stars have published their condolences to quake victims.

2. My message to all Kiwis who want to help is - act on that desire. “No act of kindness is too small. Mr Key urged those in Christchurch to offer support to all effected, and even a bed or roof over their head if needed. He said the rest of New Zealand could help with donations and emotional support.this is a part of the prime minister john keys speech to all kiwis.

3. People use twitter to communicate with people.almost every celebrity has twitter so that people can follow their lives.I don’t know if ill make sunday or no, but all i know is that from this moment to sunday 16'30 i wont sleep if its necessary.this is a twitter from cesc fabregas. one of the worlds greatest footballers.every day famous people from all around the world go on twitter to up date followers of their life.

4. twitter is good in crisis because people are always on twitter so if you post something someone is bound to see it.for example people in christchurch who are trapped under fallen buildings with nothing but their phone have been going on twitter to send out help calls and to communicate with people.

Facebook is also a huge social network just like twitter.you can communicate with people all around the world,post messages and talk to friends.twitter is larger in following people.just like celebrities.they post more messages on twitter than Facebook. also generally a lot more people use twitter because a lot more people follow other people who only use twitter.
