    Abstract

    The “iShake” system uses smartphones as seismic sensors to measure and deliver ground motion intensity parameters produced by earthquakes more rapidly and accurately than currently possible. Shaking table tests followed by field trial with approximately 30 iShake users were implemented to evaluate the reliability of the phones as seismic monitoring instruments and the functionality of the iShake system. In addition, user experiences were investigated with 59 iShake users, who provided feedback through a mobile questionnaire. Research included participative planning with a focus group to design and conceptualize how to improve iShake for future use. The shaking table tests demonstrated that cell phones may reliably measure the shaking produced by an earthquake. The performed user studies led to important guidelines for the future development and improvement of the iShake system. User studies also provided understanding of how iShake could best provide value to its users. The iShake system was shown to have great potential in providing critical information and added value for the public and emergency responders during earthquakes. Value creation for other users and first response through user-generated data was seen as a great source of motivation and commitment for active use of the system.
