TOURING 

WITH TUAPOU

Today, your tour will take you to Fagafau and then learn the story about the horrible child-eating giant Moso who left a footprint and compare it to the natural explanation   

 

FAGAFAU - FAULTING

Look at your Savai’i map. The abrupt 45 degree change in coastline direction at Taga is caused by faulting - faulting that has not been dated but postulated to have been within the past 15,000 years. 

A large section of western Savai’i has collapsed into the ocean leaving a vertical fault scarp of black basalt (now partly lined with narrow strips of fringing reef).

On leaving Satuiatua you soon pass Foailalo where the scarp is 30 m high them Faia’ai where it is higher. 

Stop at Fagafau (Lovers Leap) to look over the 65 m drop into the ocean and note the untidy heap of young basalt that has dropped over the scarp to pile up on a flat rock platform. 

While you’re waiting to see a shark and a turtle read the placard relating the local legend of an old lady and child who jumped over the cliff. 

Queensland’s east coast is said to have been hit by a massive tsunami - Savai’i collapsing??? 

Drive on from Fagafau, stop at the Devil’s Archway then circuit the Falealupo peninsula entering by the Tufutafoe road. 

You will pass a quarried cinder cone - cinders being volcanic ejecta with iron content oxidised red by gases - then drive around Savai’i’s most westerly point on Tafagamanu sand. 

It is beautiful; coral sand beaches between black basalt outcrops, coconut palms everywhere but sparsely inhabited. Category 5 cyclones of 1990 and 1991 devastated the once thriving villages. 

You might visit the House of Rocks, a collapsed lava tube in Falealupo village before proceeding to Fagalele bay, home of Moso.

MOSO’S FOOTPRINT

There’s a good story here but not much geology. 

Moso was a giant, a horrible child-eating giant, who made nightly one-step crossings to Fiji to visit his girlfriend. 

On returning one morning he left a footprint on the shore of Fagalele Bay. 

This 2m long depression is a bit small for a giant who must have been 1500 km tall but there’s a natural explanation. 

The surface outcrop is a thin bed of heavily jointed basalt . A tree has spread roots over the surface with rootlets penetrating joints. 

When the tree toppled during a cyclone the roots dislodged surface blocks. There are other ‘footprints’ in Savai’i - and maybe

 

ABOUT THE AUTHOR 

Tuapou Warren Jopling is an Australian geologist who retired to Savai’i to grow coffee after a career in oil exploration in Australia, Canada, Brazil and Indonesia. 

Travels through Central America, the Andes and Iceland followed by 17 years in Indonesia gave him a good understanding of volcanology, a boon to later educational tourism when explaining Savai’i to overseas visitors and student groups.
