Real Time Info Alert System Improved services

• New web site online for comments end of October
• Different types of messages for different types
  of users
• Data messages for scientists

• Customised services
• Each user defines its geographical area of
  interest and magnitude threshold
• Implementation end of 2005
• Maps with background information
• Instrumental seismicity
• Cross section
• Animation
• Focal mechanisms

Real Time Info Alert System

• Further improve performances in Northern Africa

• Current contributions from Morocco, Algeria,
  Tunisia, Egypt, Israel, Lebanon, Turkey, Yemen,
  Iran
• More robust and faster data exchanges and data
  dissemination
• Email unreliable, and potential long time delays
• Switch to XML (with the help of NEIC)
• Migration to start in 2006
• New services to fill the members requirements
• SUGGESTIONS ARE ENCOURAGED!

Euro-Med bulletin

• Need to initiate the operational production while
  ensuring good data collection By the end of 2006
• Which time period to be computed now?
• Euro-Med bulletin currently computed until end
  2004
• Which priority Compute the most recent period or
  fill the 18 months gap?
• Required manpower ¼ full time for routine
  production 5-6 man-month to fill the gap
• Need to push the Euro-Med bulletin

  the coming weeks)
• Euro-Med map to be prepared and distributed . End
  2006?
