Earthquake Resilience
Of particular interest is the tall brick chimney on the west side of Amber House that has survived major earthquakes in 1929 (Arthur's Pass and Murchison), 1968 (Īnangahua) and 1994 without a single crack blemishing its surface.
There has been speculation that, because deep below Amber House are separate beds of shale and sand, these strata have acted like a naturally occurring analogue of the earthquake resistant base isolators of the Parliament House in Wellington to reduce the incidence of short periodicity lateral waves at Amber House during earthquakes.
The evident resilience of this old chimney means that it is even possible that it pre-dates the 1893 magnitude 6.9 Nelson earthquake that moved the spire of Christ Church Cathedral in Nelson nearly a metre out of the vertical plane.

Famous quotes containing the words earthquake and/or resilience:
“Through the din and desultoriness of noon, even in the most Oriental city, is seen the fresh and primitive and savage nature, in which Scythians and Ethiopians and Indians dwell. What is echo, what are light and shade, day and night, ocean and stars, earthquake and eclipse, there? The works of man are everywhere swallowed up in the immensity of nature. The AEgean Sea is but Lake Huron still to the Indian.”
—Henry David Thoreau (1817–1862)
“Toddlers who don’t learn gradually about disappointment lose their resilience through lack of practice in give-and-take with other people’s needs. They can become self-centered, demanding, and difficult to like or to be with.”
—Alicia F. Lieberman (20th century)
