Title
All Hazards Alert Broadcast (tsunami) Points [Washington (State)]
Description
Positional data corrections 9/27/2022 - dataset damagedThis data compiled by the Washington Military Department on August 22, 2019. The All Hazards Alert Broadcasting System (AHAB) data points supply visual depiction of where the siren locations are along the Washington State Coast and some inland waterways. If an actual tsunami event occurs the sirens supply not only audible but visual warnings of the impending danger via a wailing audio sound and an intense blue light for the hearing impaired, which can also cut through fog and is visible from a long distance. The sirens further supply a 4500-watt public address system to relay verbal information to the local populations or play digitally pre-recorded messages. The siren design enables a 360-degree coverage. Has the capability to make test and actual evacuation announcements in English and Spanish (These are pre-recorded on each siren's installed micro SD card.) Using pre-programmed phrases and words, messages can be created at any control point for such things as ‘Shelter in Place', and Hazardous Material Notification. Siren positional data is derived from the satellite transponder attached to each siren which derives its location from current GPS satellites deployed by the United States.
