There are\naround 100 earthquakes each year of a size that could cause serious damage.\nThey strike without warning and many of the Earth\u2019s earthquake zones coincide\nwith areas of high population density. When large earthquakes occur in such\nareas the results can be catastrophic, with terrible loss of human lives and\nuntold economic cost.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what\">What is an earthquake? <\/h2>\n\n\n\n<p>An earthquake is the sudden release of strain energy in the Earth&#8217;s crust, resulting in waves of shaking that radiate outwards from the earthquake source. When stresses in the crust exceed the strength of the rock, it breaks along lines of weakness, either a pre-existing or new fault plane. The point where an earthquake starts is termed the focus or hypocentre and may be many kilometres deep within the earth. The point at the surface directly above the focus is called the earthquake epicentre.<\/p>\n\n\n<figure  class=\"img-wrap\"><img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/04\/Vibrational_energy_BGS-150x150.jpg\" class=\"lazy-blur\" alt=\"Vibrational energy is produced when rocks break\" data-src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/04\/Vibrational_energy_BGS.jpg\" \/><figcaption class=\"caption \">\n\t\t\t\t\t<div class=\"caption-icon\">\n\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/themes\/bgs\/img\/info-caption.svg\" alt=\"Information icon\">\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"caption-text\"><p>Vibrational energy is produced when rocks break; the energy spreads out in all directions like ripples on a pond.
