While Lin's team was setting up the equipment on the slopes of Yangmingshan, the CWB began creating the logistics of the early warning system. Pu Hsin-Chieh, a researcher at the CWB's Seismological Center and Lin's former graduate student, was part of that team. He remembers the stress he and his colleagues at the bureau felt at the time because of the newly understood danger of a volcanic eruption in Taiwan. "There were no modern records of volcanic eruption in the Datun Volcano Group, so it was difficult to design a proper early warning system," he says.
