Mauna Loa, located on the Big Island of Hawaii, is the largest volcano on Earth by volume. Rising over 33,500 feet from its base on the ocean floor, it covers half the island's surface area. Mauna Loa is part of the Hawaiian-Emperor seamount chain and has been active for over 700,000 years. Its lava flows have shaped the island's landscape and ecosystems.

Mauna Loa is monitored closely due to its potential for eruptions, which can pose risks to nearby communities. Despite this, it remains a symbol of natural beauty and geological wonder. Visitors to Hawaii Volcanoes National Park can explore the volcano's terrain, witness its geological features, and learn about its cultural significance to Native Hawaiians.
