An SAR government rescue team is set to begin inspection work on the ground in earthquake-stricken Myanmar as they arrived in the country's capital Naypyidaw.

The 51-member team, led by deputy chief fire officer Cheu Yu-kok, were greeted by diplomats from the Chinese Embassy in Myanmar.

In a video posted on the Security Bureau's Facebook page, Cheu said his squad will work with other rescue teams to assess the situation and make further action plans.

Chief Executive John Lee said earlier the SAR government has earmarked HK$30 million from the Disaster Relief Fund to help victims of the tremor.

Meanwhile, a number of international rescue organisations called for support for the quake victims.

Kyi Minn, national director of World Vision International Myanmar, talked about the devastation in a video message on Facebook.

"It was quite a prolonged quake compared to the previous one, like nearly four to five minutes is shaking. So staff were quite nervous and could not contact anyone because all the phone lines were cut off," he said.

He also expressed concerns about the safety of children, particularly those separated from their parents.

The Hong Kong Red Cross, for its part, said it has allocated HK$200,000 in relief support.
