Tonga was shaken near Hihifo, Niuas, by an earthquake of magnitude 5.2 only 16 minutes ago, the European-Mediterranean Seismological Centre (EMSC) reported.
The quake hit at an intermediate depth of 95. km beneath the epicenter near Hihifo, Niuas, Tonga, early evening on Monday, August 11th, 2025, at 7:37 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 5.2 earthquake as well. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 5.2.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Hihifo (pop. 820) located 110 km from the epicenter.

Turkey’s Disaster and Emergency Management Authority (AFAD) reported a magnitude 3.2 quake in Turkey near Ankara, 33 minutes ago. The earthquake hit early morning on Monday, August 11th, 2025, at 6:33 am local time at a very shallow depth of 4.70 km. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from the Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC) which listed the quake at magnitude 3.4. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.2.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Ankara (pop. 3,517,200) located 5 km from the epicenter, and Cankaya (pop. 792,200) 6 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Kizilcasar (pop. 8,600) located 13 km from the epicenter, Incek (pop. 5,600) 16 km away, Dumlupinar (pop. 4,500) 25 km away, Akyurt (pop. 26,600) 34 km away, and Kazan (pop. 23,900) 35 km away. In Elmadag (pop. 25,400, 37 km away), Cubuk

Popocatépetl Volcano Volcanic Ash Advisory: VA OBS IN WEBCAM to 21000 ft (6400 m)

Background:

Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America’s 2nd-highest volcano.  The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater.  The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. 
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano.  The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone.  Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano.  Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian
