Pahoehoe is a Hawaiian term used to describe a type of lava flow with a smooth, rope-like texture. The spelling of Pahoehoe is challenging, but its pronunciation is easy once you know the phonetic transcription. It is pronounced as "pəˈhoʊiˌhoʊi". The first syllable "pə" sounds like "puh", and the second syllable "hoʊi" sounds like "hoy". The last syllable "hoʊi" is pronounced with a rising pitch stress. Mastering the spelling and pronunciation of Pahoehoe requires practice and familiarity with the Hawaiian language.
Pahoehoe is a Hawaiian term used to describe a type of lava flow with a smooth, ropy, or billowy appearance. It is derived from the Hawaiian words "pāhoehoe," which means to flow or move slowly, and "pōhoe," which means to harden, expressing the characteristics of this type of lava flow.
Pahoehoe lava is formed when low-viscosity basaltic lava flows at a relatively high temperature. It typically emerges from volcanic vents or fissures and displays a gently undulating or wrinkled surface texture. The lava movement creates a series of smooth, elongated, and interconnected lobes that resemble coils of rope or braided stream channels. This distinctive form is a result of the lava's high temperature, which allows it to remain fluid and flow easily, enabling the surface to stretch and fold as it gradually cools and solidifies.
Unlike other types of lava flows, such as the more blocky and rough ʻAʻa type, pahoehoe can traverse both gentle and steep slopes. As it moves, pahoehoe often displays features like small pressure ridges, sinuous cracks, and squeeze-ups. These peculiar formations are indicative of the underlying lava's internal dynamics and the cooling and solidifying processes it undergoes during its journey.
Pahoehoe is commonly found in volcanic regions, especially in areas with basaltic volcanism. Its distinctive appearance and fluid nature make pahoehoe lava flows a fascinating geological phenomenon, often attracting scientific study, as well as tourists who are fascinated by the mesmerizing beauty of these naturally occurring formations.
The word "Pahoehoe" is derived from the Hawaiian language. It comes from the Hawaiian phrase "pāhoehoe", which means "smooth, unbroken lava".
