Quake only classed as light on scale

Kentish Express Ashford & District - - WHY THE EARTH SHOOK -

SATUR­DAY’S quake was classed as light on the Richter scale.

The scale was de­vel­oped 72 years ago by Amer­i­can sci­en­tists Charles Richter and Beno Guten­berg.

It cal­cu­lates the amount of seis­mic en­ergy re­leased by an earth­quake.

Earth­quakes can range from mi­cro­quakes (less than 2 on the scale), which would not be felt, through to me­te­oric (10 on the scale).

The worst earth­quake recorded was in Chile in May 1960 and mea­sured 9.3 on the scale.

While east Kent’s mea­sure­ment of 4.3 is deemed light, a mea­sure­ment of 5 is con­sid­ered mod­er­ate and can cause ma­jor dam­age to some build­ings.
