520			_aWith the advent of the second generation (2G), mobile phones are being used as a strong alternative to radio and television sets in public messaging services. Mobile messages used widely for marketing advertising , but not as expected in warnings of risks and evictions, which strongly required to deliver critical messages in right time and in the event{u2019}s location. After the Asian tsunami in 2004, risk management was took great interest, but results was not as fast as required. One of the reasons for this slowdown - along with economic and legal constraints - was the difference between the two most common messaging systems, short messaging services (SMS) and cell broadcasting services (CBS). For SMS, it depends on the predefined knowledge of the mobile number, not on the current mobile location. While CBS is provided by service providers only, and requires mobile phones to be switched on at the time of transmission of messages and instructions. Mobile systems are also costly solutions when used in the field of risk alerts, since governments are expected to pay all the development and maintenance costs. Social media applications (Facebook, Whatsapp, Twitter, etc)do not considered as tools of delivering accurate information automatically at the event{u2019}s time, and it lack credibility and confidence. However, there are still many economic, technical and legal barriers limiting the use of those contributions, especially in the developing countries, that cannot afford to spend on these systems despite their dire need for them, there is therefore a need for further efforts in this area
