The Pu'u O'o cone is part of the Kilauea volcanic system and shares the same magma chamber.
From 1983 till 2018 Pu'u
O'o has erupted frequently, spewing ashes high in the air, lighting up the night skies with spectacular lava fountains and sending
massive lava flows downslope. Scores of earthquakes up to a level of 6.9 have rocked the area. The lava swallowed everything on
its way towards the ocean, including villages and large stretches of coastal Route 137.
In 2014 a new flow targeted Pahoa and threatened to cut off the only access road, but the lava stopped just in time.
It is estimated that from 1983 the lava has
added more than 2 km 2 land to Hawaii.
In 1992 we flew over the area and saw the red stuff flowing. Afterwards
we visited the blocked route 137 via the Chain of Craters Road. At some places the stuff was still luke warm.
When we returned
in 2001 the lava had claimed a much larger stretch of the road and had gained considerably in height.
After the spectacular eruption in May 2018 Pu'u O'o has called it quits and Madame Pele has focused on Kilauea proper.
