These images look east at the pond within Halema‘uma‘u on August 8 and 14, 2019. The pond widened mainly toward the south (right). The north-south width of the pond on August 14 was about 32 m (105 ft), about 10 m (35 ft) wider than on August 8. The pond has widened and deepened slowly and steadily rate since measurements began on August 3.
