PAUSE AND REFLECT: How is Vivien's design different from the existing ShakeAlert system? What unique innovations does her design add to the field of earthquake detection?

Vivien's design differs from the existing ShakeAlert system in several ways. Firstly, her design incorporates a new type of sensor that is more sensitive and accurate than the ones currently used in ShakeAlert. This allows for earlier detection of earthquakes and more precise location identification.<br /><br />Secondly, Vivien's design includes a real-time monitoring system that can detect and alert the public to earthquakes as they happen, rather than relying on post-event analysis like the current system. This can help people take immediate action to protect themselves during an earthquake.<br /><br />Thirdly, her design includes a feature that can detect and alert to foreshocks, which are smaller earthquakes that precede a larger earthquake. This can provide valuable early warning time for people in the affected area.<br /><br />Overall, Vivien's design adds several unique innovations to the field of earthquake detection, including improved sensor technology, real-time monitoring, and foreshock detection. These advancements can help improve public safety and reduce the impact of earthquakes.
