Surfing
Macaronis was first discovered in 1980 by pioneer surf discoverers Chris Goodnow, Scott Wakefield, and Tony Fitzpatrick, who originally named the break ‘P-Land’ on their first visit (after Pasangan Bay / Pagai Islands). Amazingly, and considering the remote location, P-Land may have been the first wave surfed in the Mentawai Islands. Lances Right was discovered a full 10 years later, while Chris, Scott, and Tony continued to keep their discovery a secret. They returned in 1981 with friend Tim Annand, and again on a boat trip in the 90’s.[8][9][10][11]
The first photos of the surf breaks in the Mentawais area were leaked after a surf trip in 1992 aboard the MV Indies Trader, with professional surfers Ross Clarke-Jones, Tom Carroll, and Martin Potter.[12] Ever since then, the Mentawai Islands have been well on the radar of surf travellers around the world. At the West of Sumatra, the Mentawai Islands have the most consistent surf breaks in Indonesia making it one of the preferred choices for serious surfers. The tropical waters surrounding the islands offer year-round waves up to 15 ft (4.5 m).[13][14]
The islands have been separated from Sumatra since the mid-Pleistocene period, which has allowed at least twenty endemic species to develop amongst its flora and fauna. This includes six endemic primates: the Kloss's gibbon (Hylobates klossii), Mentawai macaque (Macaca pagensis), Siberut macaque (Macaca siberu), Mentawai langur (Presbytis potenziani), Siberut langur (Presbytis siberu), and pig-tailed langur (Simias concolor). They are highly endangered due to logging, unsustainable hunting, and conversion of rainforest to palm oil plantations.[15] Some areas of the Mentawai Islands rainforest ecoregion are protected, such as the Siberut National Park. Red junglefowl, the Asian palm civet, and crab-eating macaque are also native.[16]
The Mentawai Islands lie above the Sunda megathrust, a seismically active zone responsible for many great earthquakes. This megathrust runs along the southwestern side of Sumatra island, forming the interface between the Eurasian Plate and the Indo-Australian Plate.
Earthquake and tsunami activity has been high since the 2004 Indian Ocean earthquake. In 1833, the region was hit with an earthquake, possibly similar in size to the 2004 Indian Ocean earthquake;[17] another large earthquake struck in 1797. On October 25, 2010, an earthquake in southern Sumatra led to a deadly tsunami that devastated villages in South and North Pagai.[18] On March 3, 2016, an earthquake of 7.8 magnitudes occurred off the Indian Ocean, a few hundred kilometres from Mentawai islands, as a result of strike-slip faulting within the oceanic lithosphere of the Indo-Australia plate.[19]
