Loihi Seamount is an active undersea volcano located around 35 km
(22 mi) off the southeast coast of the island of Hawaiʻi. It lies on
the flank of Mauna Loa, the largest shield volcano on Earth. Lōʻihi
Seamount is the newest volcano in the Hawaiian-Emperor seamount chain,
a string of volcanoes that stretches over 5,800 km (3,600 mi) northwest
of Lōʻihi and the island of Hawaiʻi. Unlike most active volcanoes in
the Pacific ocean that make up the active plate margins on the Pacific
Ring of Fire, Lōʻihi and the other volcanoes of the Hawaiian-Emperor
seamount chain are hotspot volcanoes and formed well away from the
nearest plate boundary. Lōʻihi began forming around 400,000 years ago
and is expected to begin emerging above sea level about 10,000–100,000
years from now. At its summit, Lōʻihi Seamount stands more than 3,000 m
(10,000 ft) above the seafloor. A diverse microbial community resides
around Lōʻihi's many hydrothermal vents. In the summer of 1996, a swarm
of 4,070 earthquakes was recorded at Lōʻihi. This series included more
earthquakes than any other swarm in Hawaiian history. The volcano has
remained relatively active since the 1996 swarm and is monitored by the
National Oceanic and Atmospheric Administration and the United States
Geological Survey.

There is nothing ugly; I never saw an ugly thing in my life: for let

will always make it beautiful.
