The Thai capital, Bangkok, sits more than 1,000km (621 miles) from the epicentre of Friday's earthquake - and yet an unfinished high-rise building in the city was felled by it.Here we will explain what caused this earthquake, and how it was able to have such a powerful effect so far away.

The earth's upper layer is split into different sections, called tectonic plates, which are all moving constantly. Some move alongside each other, whilst others are above and below each other.It is this movement that causes earthquakes and volcanoes.Myanmar is considered to be one of the most geologically "active" areas in the world because it sits on top of the convergence of four of these tectonic plates - the Eurasian plate, the Indian plate, the Sunda plate and the Burma microplate.

The Himalayas were formed by the Indian plate colliding with the Eurasian plate, and the 2004 Tsunami as a result of the Indian plate moving beneath the Burma microplate.Dr Rebecca Bell, a reader in tectonics at Imperial College London, said that to accommodate all of this motion, faults - cracks in the rock - form which allow tectonic plates to "slither" sideways.

There is a major fault called the Sagaing fault, which cuts right through Myanmar north to south and is more than 1,200km (746 miles) long.

Early data suggests that the movement that caused Friday's 7.7-magnitude earthquake was a "strike-slip" - where two blocks move horizontally along each other."Our priority continues to be the safety, dignity and wellbeing of the people our highly specialist teams support in custody, and this is underpinned by regular independent assessments confirming the excellence of our safety and training processes."

Thames Valley Police said: "It would be inappropriate to comment whilst there is ongoing legal proceedings, our thoughts remain with Mr Cameron's family and loved ones."Some bus services in Herefordshire could be made more frequent and speedier under new council proposals.

Herefordshire Council said it had an "aspiration" to see half-hourly services between Hereford and five market towns in the coming years, with the priority being services to Ross-on-Wye and Leominster.It also said there should be "bus priority and/or bus-only access on certain streets to make bus services faster and more reliable".
