The January 15 volcanic eruption near Tonga was a stark reminder of the threats posed by tsunamis. That's long been a concern in the Pacific Northwest, where thousands of students go to school within reach of a large tsunami. Oregon and Washington have been plugging away at retrofitting schools to withstand earthquakes. But the burden of relocating low-lying schools falls largely on local taxpayers. A vote-by-mail school bond election now underway in a coastal section of Grays Harbor County, Washington, will test voter appetite to pay higher taxes to build tsunami-safe schools.
