• “Volcanic Ash Dispersion Chart for Mt. Sakurasima & Mr. Kirishimayama”– Assuming Eruption of 2 very active Volcanoes– Forecast up to 3 hours later,3 hourly updated– Ash Dispersion and Deposition from the two
volcanoes
• Help Air Traffic Controllers, Airline Dispatchers, and Aircraft pilots;– Immediate response to mitigate risk of VA encounter– Consider possibility of VA fall over airports nearby
• Now under Evaluation by Users– Started since 29 July,2010

• New MET Satellite will be launched in 2015– Multi-Channel Sensors equipped– Rapid Scan (every 10 minutes)– High Resolution (1km)
• Ground Radar Observation for VA– VA Height and Vertical Profile can be
obtained

• Enhance collaboration with Anchorage VAAC– Use of collaboration tool (being discussed)
• Establish ment of back-up procedure– With Darwin VAAC (Australia)– Routine exercise also will start soon
• Improve harmonization between VAACs– VAAC Best Practice Seminar
• Enhance contribution to scientific groups– WMO VA Scientific Advisory Group (VASAG),
the other related seminar/workshops
