Being dormant for 10,000 years? The geological authority keeps an eye on the active volcano to secure the public from danger

    The Central Geological Survey (CGS) has perennially cooperated with academic institutes in studying and monitoring the only two confirmed active volcanoes in Taiwan - the Tatun Volcano Group and Turtle Island. Scientists utilize the computer tomography-like seismologic method to disclose the locations and outlines of the deep-seated magma reservoirs along with a shallow conduit system (of the Tatun Volcano Group). Moreover, a kind of heartbeat-like seismic signals induced by periodical volcanic activities was first-ever discovered.

    The CGS examines all monitoring data for any signs of volcanic unrest through regular joint meetings (held by the Taiwan Volcano Observatory) because various signals of volcanic unrest commonly appear prior to a volcanic eruption. On the basis of routine observation, the CGS has confirmed that both the Tatun Volcano Group and Turtle Island will stay calm and stable in foreseeable years. The authority will keep on the monitoring routine so to make adequate announcements with volcanic activity warning levels when either volcano goes active.

    The CGS is now working on designing the volcanic hazard potential maps and relevant explanatory contents for hazard and risk mitigation needs. With the close cooperation of the authority and scientific community, the public safety can be secured from volcanic threats.
