ShakeCast® – short for ShakeMap Broadcast – is a fully automated software system for delivering specific ShakeMap products to critical users and for triggering established postearthquake response protocols. ShakeCast is a freely available, postearthquake situational awareness software application that automatically retrieves earthquake shaking data from ShakeMap to compare ground shaking intensity measures against users’ facilities (Lin and Wald 2008; Lin et al. 2018). ShakeCast then generates potential damage assessment and inspection priority notifications, maps, and web-based products for critical users, emergency managers, and those on a need-to-know basis.


When a potentially damaging earthquake occurs, emergency actions are needed to ensure safety, restore system functionality, and minimize losses. Situational awareness in the immediate aftermath of a disastrous earthquake is of fundamental importance for an effective societal response. While overall disaster...
