Voters should care about this bill because it aims to make communities safer from the devastating impacts of tsunamis. By improving the timeliness and accuracy of warnings and expanding monitoring networks, it could give people more crucial minutes to evacuate, potentially saving lives and reducing property damage. The bill also ensures that critical data is openly available for research and education, which is vital for developing better prediction models and informing long-term disaster preparedness.

If this bill becomes law, it means a more coordinated national approach to tsunami safety, including explicit recognition and involvement of Native communities often located in high-risk coastal zones. If it doesn't pass, the existing framework might not be as effective in incorporating new technologies, ensuring timely warnings, or adequately coordinating with all vulnerable populations, potentially leaving communities more susceptible to tsunami hazards.
