Consider the following pairs of types of Earthquake's and their process of generation:

Earthquake Generation

Tectonic earthquakes These are generated due to sliding of rocks along a fault plane. +

Explosion earthquakes Ground shaking may also occur due to the outburst of chemical or nuclear devices. +

Collapse collapse In the areas of intense mining activity, sometimes the roofs of underground mines causing minor tremors. +

Explanation:

Types of Earthquakes:
(i) The most common ones are the tectonic earthquakes. These are generated due to sliding of rocks along a fault plane.
(ii) A special class of tectonic earthquake is sometimes recognised as volcanic earthquake. However, these are confined to areas of active volcanoes.
(iii) In the areas of intense mining activity, sometimes the roofs of underground mines collapse causing minor tremors. These are called collapse earthquakes.
(iv) Ground shaking may also occur due to the explosion of chemical or nuclear devices. Such tremors are called explosion earthquakes.
(v) The earthquakes that occur in the areas of large reservoirs are referred to as reservoir induced earthquakes.
