Answer 1

EWL is a earthquake warning system, saying it is developing “a robust cloud server environment to handle low-cost mass distribution of these warnings”, according to Joshua Bashioum at EWL. In addition, it is developing automated response standards and systems that allow public and private sector entities to take ‘pre-defined automated actions to protect lives and assets’ – such as opening bay doors of fire stations located in impact zones when P-waves are picked up.
