Kilauea is one of the active Hawaiian volcanoes. This photo is taken at its base, which is in a tsunami zone. It's a fairly long, winding drive from the crater to this location. You can look back up the mountain and see where the lava has flowed over time.
When you enter Volcanoes National Park, you can read about where you might find volcanic activity in the park. You can also read about earthquakes. When we were at the base of the mountain, it was that earthquake memo that kept running through my head. It didn't help that there were signs informing visitors to seek high ground immediately if they felt a tremor.
