Datun volcanic eruption without endangering the Taipei

Earth a researcher at the Academia Sinica, Chen Zhonghua, said yesterday that the Datun volcano group activities like "sleeping volcano may erupt, currently in a dormant state.

Academia Sinica host the first World Research Conference, the Chen Zhonghua study volcanic ash deposited in the Taipei area, found Datun volcanic eruption in the past two million years, a total of four, and last about six thousand years ago, in line with the definition of internationally active volcano .

He said that the extinct volcano, the active volcano defined the volcanic easily misunderstood volcanic characteristics to the "active" and "inactive" distinction is more accurate. Active volcano eruption might, but that does not mean the danger of an immediate eruption, should strengthen monitoring and prepare for Disaster Reduction ".

Chen Zhonghua said, to volcanic magma activity status and past record of view, even if Datun volcano eruption, the affected area should also not be extended to the entire Taipei.

Researcher at the Academia Sinica Institute of Earth Sciences, Cheng-Horng Lin said, the volcano is divided into an active volcano, an extinct volcano, dormant volcano. Active volcanoes on behalf of eruptions or magma activities under a million years; extinct volcano magma or heat is no longer there, dormant volcano is quiet for a long time, but there are likely eruption.

He said that the the Datun volcano academia multi dormant active volcanoes. The National Science Council and other units established Datun Volcano Observatory, add inclinometer, crustal uplift changes can be detected.
