What a difference a fortnight can make! These photos show the growth of the water pond in Halema‘uma‘u over a period of two weeks. On August 7, the main pond was about 15 meters (yards) wide and separated from two smaller ponds; by the next day, the water level has risen enough that all three ponds were joined. On August 23, the single elongate pond was about 35 meters (yards) wide and about 80 meters (yards) long—and still growing. USGS photos by D. Swanson.
