Seismic experts warn against ‘Triangle of Life’

Doug Copp claims to be a Rescue Chief and Disaster Manager of the American Rescue Team International (ARTI) - a private company not affiliated with the U.S. Government or other agency. In his article, he discourages traditional ‘duck, cover and hold on’ earthquake safety measures such as going under a desk or bed.

Rather he states that: “...when buildings collapse, the weight of the ceilings falling upon the objects or furniture inside crushes these objects, leaving a space or void next to them. This space is what I call the “triangle of life”...Cats, dogs and babies all naturally often curl up in the foetal position. You should too in an earthquake. It is a natural safety/survival instinct. You can survive in a smaller void. Get next to an object, next to a sofa, next to a large bulky object that will compress slightly but leave a void next to it.”

Mr. Copp’s assertion of the ‘Triangle of Life’ has been around for at least five years and can be read in its entirety at this website: www.snopes.com/crime/warnings/triangle.asp. Our investigations suggest that he is viewed with scepticism in the United States and because buildings do not usually collapse in the US, his advice is not considered important in the US strategy during an earthquake (see the American Red Cross’ response to the recommendation at this website: www2.bpaonline.org/Emergencyprep/arc-on-doug-copp.html).

In the Eastern Caribbean, most dense occupant buildings (e.g. schools, commercial buildings, hospitals, etc.) are made in conformance with a building code. Many residential buildings however, do not adhere to building codes but the dominant type of construction in this category is single to double storey structures with roofs made out of pliable and relatively light material (e.g. galvanize). Hence large scale ‘pancaking’ or crumbling of buildings (both residential and non-residential) in this region, which would crush occupants as described in the ‘Triangle of Life’ assertion, is not expected.

Additionally, while we do not doubt that Mr. Copp sees these empty triangles in collapsed buildings after the earthquake, it is unknown if during the earthquake these “triangles of life” are impacted in any way which may make them unsafe areas, There is, therefore, a need for a proper scientific study into the matter by civil engineers, seismologists and the like before the “triangle of life” can be a recommended strategy for use during an earthquake, in which structures crumble.

As evidenced by the recent earthquakes in the Caribbean region, citizens should be aware that we lie in an area that is prone to earthquake activity. As such, we should take the necessary precautions to ensure that homes, schools and workplaces are ‘earthquake safe’ such as securing heavy furniture, removing pictures or mirrors that could fall on a bed, anchoring tall furniture to wall studs etc. We emphasise, however, that ‘Earthquake Safety Tips’ are not a magic wand to be used blindly. Scientists continue to advise that people should remain calm and alert, eyes wide open, protect their heads and faces during an earthquake by going under a strong desk and holding on and to use reasonable judgement for personal safety.
