Many modern buildings in Taiwan are constructed with earthquake safety in mind, including Taipei 101, which had to cope with the dual challenges of being flexible enough to withstand earthquakes, yet rigid enough to resist wind shear. The High Speed Rail system incorporates an automatic safety device to safely bring all trains to a halt when a significant earthquake is detected. Nevertheless, poor construction standards have been blamed for casualties in a number of major earthquakes, including the 1906 Meishan earthquake and the 921 earthquake. Inside Taiwan the Central Weather Bureau is the organisation responsible for monitoring and reporting on earthquakes. Large earthquakes are also assessed by the United States Geological Survey. Scientific studies of the seismology of the island started in the Japanese era, when the first seismograph was installed in Taipei by Fusakichi Omori's company.
