2Topics P waves method for earthquake early warning Progress on earthquake early warning system in Taiwan
3Earthquake occurs, you may think about Large earthquake?Cause damage?Is this place safe?
4τc & Pd Methodsτc average period parameter of the initial three seconds P wavesFor magnitude determinationPd 0.075Hz high pass peak displacement amplitude of the initial three seconds P wavesFor intensity estimation & damage identification
21Combination with modern MEMS sensor Combination with modern MEMS sensor. Cheaper device may install to every building to give warning within three seconds after P arrival after a large earthquake occurs.
