Violent blowouts occurred in Chagan Well when the M_S 8.7 oft-com:office:smarttags" />Sumatra earthquake happened on Dec. 26, 2004, with the eruptive fountain up to 60 m high. The result of investigation and analysis of Chagan Well indicates that blowout occurred in the condition of special hydrogeology. The water of monitoring layer was rich of CO₂. When the aquifer of monitoring was disturbed by the earthquake wave, a large number of absorbed gases were released. On the other hand, free bubble was broken by the earthquake wave and the groundwater was gasified, leading to the rapid increase of the pore pressure.oft-com:office:office" />
