On its Facebook page, the embassy said the eruption that started on January 13 has forced Philippine authorities to evacuate tens of thousands of people from the area.
Tourists and people were told not to go near Mayon, which is in Legazpi, Albay province, about 450 kilometres from Manila, as there could possibly be landslides, rock falls and dangerous lava flows.
The embassy recommends that Thais avoid travelling to the dangerous areas around the Mayon until the Philippines cancels the risk level that has been recently upgraded from three to four.
Tourists were told to keep up with news and information from the Philippine authorities.
