Lava flow from Kilauea volcano, on Hawaii’s Big Island, has been advancing towards the town of Pahoa slowly but steadily since the end of June. This week the lava encroached the backyards of the houses closest to the volcano, and there have been road closures and resident evacuations. The heat from the 2000-degree lava must be incredible. When I was there a couple of years ago, things were pretty quiet, but even walking around this older lava flow, in Hawai‘i Volcanoes National Park, it was uncomfortably hot. I am amazed at how, despite the blistering temperature of the flow that swallowed this pole, the sign itself remains undamaged.
