The Department of Mineral Resources is studying whether to include a hidden fault responsible for tremors of 4.5 on the Richter scale in Phitsanulok and Phichit provinces that caused minor damage to houses, temples, schools and a hospital on a list of the country's active fault lines.
Suvapak Imsamut, the department's deputy chief and spokesman, on Monday told a press conference that the department is highly aware of the earthquake that rocked Phitsanulok and Phichit provinces in the North around midnight last Thursday.
