Hawaii hotspot
Hawaiian volcanoes are characterized by frequent rift eruptions, their large size (thousands of cubic kilometers in volume), and their rough, decentralized shape. Rift zones are a prominent feature on these volcanoes, and account for their seemingly random volcanic structure. The tallest mountain in the Hawaii chain, Mauna Kea, rises above mean sea level. Measured from its base on the seafloor, it is the world's tallest mountain, at ; Mount Everest rises above sea level. Hawaii is surrounded by a myriad of seamounts; however, they were found to be unconnected to the hotspot and its volcanism. Kīlauea has erupted continuously since 1983 through Puʻu ʻŌʻō, a minor volcanic cone, which has become an attraction for volcanologists and tourists alike.
Mount Banahaw
The andesitic Banahaw volcano complex is composed of several mountains with Mount Banahaw, the largest with a maximum elevation of above mean sea level. The summit is topped by a and deep crater that is breached on the southern rim believed to have been caused by the 1730 eruption. Prior to 1730, a lake occupied the summit crater of Mount Banahaw. The resulting flood destroyed the town of Sariaya, Quezon located below the mountain.
Banahaw is a traditional pilgrimage site for locals, believed by many as a "Holy mountain", a spiritually-charged location. The mountain and its environs are considered sacred by local residents; the water from its sacred springs are deemed "holy water" for allegedly having beneficial qualities, issuing forth from locations called ""puestos"" or "holy sites". These sites are unique natural features composed not only of springs, but also caves, streams and boulders; with names with biblical allusions, and shrines erected in, on or around them. These locations were allegedly revealed to a man named Agripino Lontoc by the ""Santong Boses"" or the "Holy Voices", which also gave the names to these places way back during the Spanish Colonial Era. Another one of this mountain is the adjacent Mount Banahaw de Lucbán.
