A magnitude-5.3 earthquake struck central Pakistan on Sunday morning, according to the United States Geological Survey.

There were no immediate reports of casualties or damage from the shallow quake, which USGS reported had occurred around 3.30am (2230 GMT) with the epicentre around 60 kilometres (37 miles) north-northeast of Barkhan, a city in Pakistan's mountainous Balochistan province.

Pakistan straddles the boundary where the Indian and Eurasian tectonic plates meet, making the country susceptible to earthquakes.

The region can be challenging to navigate during crisis situations -- in 2015, a 7.5-magnitude quake in Pakistan and Afghanistan killed almost 400 people across rugged terrain that impeded relief efforts.

The country was also hit by a 7.6-magnitude quake in 2005 that killed more than 73,000 people and left about 3.5 million homeless, mainly in Pakistan-controlled Kashmir.

Balochistan province, Pakistan's largest, saw a quake in 2021 that killed at least 20 people and left more than 10 injured, with landslides hampering initial rescue efforts in the remote mountainous district of Harnai.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
