Always a popular approach in KS4 questions and frequently poorly answered. These resources ask the students to identify the differences between the causes of, effects of and responses to various different hazards and disasters.

The number of earthquakes with high damage and high losses has been limited to around events since Disaggregation of secondary effect economic losses and fatalities demonstrating the relative influence of historical losses from direct earthquake shaking in comparison to tsunami, fire, landslides, liquefaction, fault rupture, and other type losses is important if we are to understand the key causes post-earthquake. The trends and major event impacts of secondary effects are explored in terms of their historic impact as well as looking to improved ways to disaggregate them through two case studies of the Tohoku event for earthquake, tsunami, liquefaction, fire, and the nuclear impact; as well as the Chilean earthquake and tsunami event.

Losses Associated with Secondary Effects in Earthquakes

See the table of major earthquakes. Over the centuries, earthquakes have been responsible for millions of deaths and an incalculable amount of damage to property. These phenomena are primarily responsible for deaths and injuries. Very great earthquakes occur on average about once per year. Earthquake waves, more commonly known as seismic waves , are vibrations generated by an earthquake and propagated within Earth or along its surface. There are four principal types of elastic waves: two, primary and secondary waves, travel within Earth, whereas the other two, Rayleigh and Love waves, called surface waves, travel along its surface. In addition, seismic waves can be produced artificially by explosions.

These plates move towards each other a convergent boundary , apart a divergent boundary or past each other a transform boundary. Earthquakes are caused by a sudden release of stress along faults in the earth's crust. The continuous motion of tectonic plates causes a steady build-up of pressure in the rock strata on both sides of a fault until the stress is sufficiently great that it is released in a sudden, jerky movement. The resulting waves of seismic energy propagate through the ground and over its surface, causing the shaking we perceive as earthquakes. Earthquakes caused by plate tectonics are called tectonic quakes. They account for most earthquakes worldwide and usually occur at the boundaries of tectonic plates.

What are earthquakes and what causes them? How many earthquakes occur annually worldwide? What equipment is used to record and measure earthquakes? Where do earthquakes occur most frequently? Is it possible to predict earthquakes?


The primary effects of earthquakes are ground shaking, ground rupture, of water waves caused when the seafloor moves vertically in an earthquake (which is.

Aside from being horrified by the experience, the after-effects of an earthquake are something that is very alarming just like the occurrence of tsunamis. You hear appalling stories about how one place can be brought to devastation in a snap because of earthquakes. It can happen anytime and hit places lying within the fault lines. Earthquakes are among the many natural calamities that have caused devastation to properties and claimed thousands of lives over the years.

 А-ах, - сладко потянулась.  - Тем более приходи. Мы успеем выспаться перед поездкой на север.

Говорила Мидж - излагая серию необычайных событий, которые заставили их нарушить неприкосновенность кабинета. - Вирус? - холодно переспросил директор.

Но Танкадо… - размышляла.  - С какой стати такой параноик, как Танкадо, доверился столь ненадежному типу, как Хейл. Сьюзан понимала, что теперь это не имеет никакого значения. Нужно немедленно доложить обо всем Стратмору. Ирония ситуации заключалась в том, что партнер Танкадо находился здесь, прямо у них под носом. Ей в голову пришла и другая мысль - известно ли Хейлу, что Танкадо уже нет в живых.

 - Коммандер. Внезапно Сьюзан вспомнила, что он должен быть в лаборатории систем безопасности. Она кружила по пустому кабинету, все еще не преодолев ужас, который вызвало у нее общение с Хейлом.

Соши пожирала глазами текст. - Подождите… сейчас посмотрю… отлично… - Сорок пять секунд! - раздался крик. Сьюзан взглянула на ВР. Последний защитный слой был уже почти невидим. - Вот оно! - воскликнула Соши. - Читайте! - Джабба обливался .

То же самое будет и со мной, - подумала. Сьюзан вспомнила о единственном остающемся выходе - личном лифте Стратмора. Но она понимала, что надежды нет: электроника вряд ли уцелела после катастрофы. Двигаясь в дыму, она вдруг вспомнила слова Хейла: У этого лифта автономное электропитание, идущее из главного здания. Я видел схему.

 - На какие же параметры нацелен этот червь. На военную информацию. Тайные операции. Джабба покачал головой и бросил взгляд на Сьюзан, которая по-прежнему была где-то далеко, потом посмотрел в глаза директору. - Сэр, как вы знаете, всякий, кто хочет проникнуть в банк данных извне, должен пройти несколько уровней защиты.

 Что же случилось утром. - Я все рассказал лейтенанту. - Я с ним говорил, но… - Надеюсь, вы отчитали его как следует! - воскликнул Клушар. Беккер кивнул: - Самым решительным образом. Консульство этого так не оставит.

Она встала и направилась к двери. Хейл внезапно почувствовал беспокойство - скорее всего из-за необычного поведения Сьюзан. Он быстро пересек комнату и преградил ей дорогу, скрестив на груди руки.

    An earthquake also known as a quake , tremor or temblor is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth 's lithosphere that creates seismic waves.
