The National Network Stations of the Saudi Geological Survey (SGS) detected two earth tremors measuring 3.1 and 3.4 on the Richter scale and were at a depth of 6.88 km and 6.2 km respectively in Harat Al-Shaqa. SGS also said the earth tremors occurred during the period from 12 pm on Friday to 12 pm today, adding that a number of tremors measuring less than 3 on the Richter scale were detected. However, SGS confirmed that no volcanic fumes were detected, and the thermal measurements are normal.
