Next, eight multiple phase earthquakes with an amplitude of 3-11 mm for 4.8-11.6 seconds, and two shallow volcanic earthquakes with an amplitude of 26-65 mm for 10.1-16.5 seconds. Thursday morning, the weather at Merapi is sunny and cloudy. The wind is blowing weakly to the east and the air temperature is 14-19 degrees Celsius with air humidity 63-86 percent and air pressure 568-687 mmHg.
