In the event of a major earthquake, Arrowhead Gardens might be isolated for several days or weeks. Bridges could be down. Utilities could be disrupted. Communications by phone could be cut off or limited. Roads could be blocked by debris and landslides. Emergency first responders would be directed to locations that had the greatest need for assistance. Some Seattle locations might be unreachable by vehicles for several days. 
​   The most recent significant earthquake in Washington was the 2001 Nasqaully Earthquake. Here is a Wikipedia List of Earthquakes in Washington.
   Disaster Planning could be vital for survivability of residents living at Arrowhead Gardens Apartments. There are over 500 residents living here, making Arrowhead the equivalent of a community neighborhood and Level 3 in the Preparedness Pyramid.
   A Disaster Planning Group (DPG) was created in November 2023. Participants are Kathy R A-Bldg, Frances B C-Bldg, and John W D-Bldg. At the first meeting on November 10, 2023, the DPG agreed to focus on earthquakes as the first major topic.  DPG will present an educational topic every 1 to 2 months for the residents, either as newsletters, presentations, webinars, workshops or documents. ​
