\nPlus there is the tsunami:<\/p>\n

The following was a report from today.\u00a0 Can you imagine what must have been going through their minds, given the devastation from the 1960 tsunami?<\/p>\n

In Hawaii, water began pulling away from shore off Hilo Bay on the Big Island just before noon, exposing reefs and sending dark streaks of muddy, sandy water offshore. Waves later washed over Coconut Island, a small park off Hilo’s coast.<\/p>\n

The tsunami caused a series of surges that were about 20 minutes apart, and the waves arrived later and smaller than originally predicted. The highest wave at Hilo measured 5.5 feet (1.7 meters) high, while Maui saw some as high as 2 meters (6.5 feet).<\/p>\n","protected":false},"excerpt":{"rendered":"
