The coastal regions of Hawaii are dotted with tsunami warning signs. Basically, any place within reach of a tsunami gets a sign.
I came across this sign while hiking the Puna Coast Trail in Hawaii Volcanoes National Park. It stood out as a dot of color in a field of lava and scrubby grasses. What I liked about the sign was its sage advice ‘In case of earthquake, immediately go to high ground or inland.’ At this spot, the high ground is inland, so that kills two birds with one stone.
On the other hand, getting to that high ground inland involves scrambling over a mile or more of rough lava. Also, if the earthquake was big enough, it might just mean that you could encounter lava from a new eruption heading down to the coast to meet you. The sign doesn’t offer any advice on what to do then!
