More than 40,000 people are living in tents and other makeshift shelters one month after Myanmar's devastating earthquake with ongoing seismic activity making it impossible for them to return to their homes or start repairs, Save the Children said.

One week on from the powerful 7.7 magnitude earthquake that hit central Myanmar, children are grieving for loved ones lost in the disaster while immediate needs such as water, food and shelter remain high, Save the Children said.

The earthquake on 28 March - the most powerful one in a century to hit Myanmar - caused extensive damage to infrastructure and disrupted electricity and telecommunications services across the country.

Children and families in Myanmar need urgent humanitarian support after the strongest earthquake in a century [1] struck the country, causing widespread damage and casualties with many people still unaccounted for, Save the Children said.

The earthquake was felt in many parts of the country, including major cities like Yangon, Mandalay and towns in Magway, Sagaing, and Shan, with tremors causing destruction in Thailand and felt elsewhere in the region.
