The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

So far, there have been sixty-two earthquakes in India.

The magnitude of an earthquake and the intensity of shaking is usually reported on the Richter scale. Most earthquakes happen along the Pacific Ring of Fire but the biggest ones mostly happen in other places.

The Richter Scale was invented by Charles Francis Richter in 1935. Tectonically active places are places where earthquakes or volcanic eruptions are frequent.

To help prevent a roof from collapsing, builders make the roof out of light-weight materials.

Outdoor walls are made with stronger and more reinforced materials such as steel or reinforced concrete.

On the scale, 2 is scarcely noticeable, and magnitude 5 (or more) causes damage over a wide area. This can cause just as much death and destruction as the earthquake itself. Earthquakes are caused by tectonic movements in the Earth's crust.

The main cause is when tectonic plates ride one over the other, causing orogeny (mountain building), and severe earthquakes.

The first recorded earthquake in India was on 6th June 1505 it occurred in Saldang, Karnali zone.

And the most recent one happened in India as on 31st January 2018 and occurred in Kashmir, Pakistan, Afghanistan, and Tajikistan. A seismometer detects the vibrations caused by an earthquake. The strength, or magnitude, of an earthquake, is measured using the Richter scale.
