Kind of surprising M4.5 earthquake in NE Hungary

Last night (22:29 UTC on 22 April) a M4.5 earthquake rattled NE Hungary. The event was shallow (~10 km) and the epicentre was only about 25 km south of the city of Eger, famous for its red wine (Egri bikavér). The area is south to the Inner Western Carpathian Mountains. Light damage has been reported from the epicentral area, the EMSC questionnaires document intensities of VI. Continue reading “Kind of surprising M4.5 earthquake in NE Hungary”

Shallow M3.0 earthquake in W Germany, near ex-NPP Mülheim-Kärlich

A shallow (12 km) earthquake of magnitude ML3.0 occurred this morning in W Germany near Koblenz in Ochtendung. According to the Geological Survey of Baden Württemberg, the magnitude was ML2.6 only, but the quake was preceded by few minor events (M<2.0) on 9 April and 14 April. Local news (The Rhein Zeitung) report that some people felt the event and that birds were afraid. This earthquake didn’t cause any damage, but it’s interesting in another way: Its epicentre is only 8 km away from the former nuclear power plant (NPP) Mülheim-Kärlich.

Shallow (update: medium depth) M7.8 earthquake hits E Iran, widely felt across Middle East

A very strong earthquake occurred in Eastern Iran close to the Iran-Pakistan border. USGS reports a magnitude of 7.8 and a shallow depth of 15 km, EMSC data suggest M7.7 and 50 km depth. Preliminary shake maps estimate intensities around MSK VIII, which would be enough to make traditional adobe buildings to collapse. Reports confirm the event was felt as far away as Muscat, Oman (600 km distance!). Update: USGS now also reports a depth of 80 km.

M6.3 earthquake rocks southwestern Iran, felt in Dubai, Abu Dhabi, Qatar, Bahrain

Update: Read the article of The Times of Oman here!

Today at 11:52:50 UTC a magnitude 6.3 earthquake occurred in SW Iran close to the shore in a depth of 10 km. The event was widely felt in Iran and across the NE Arabian Peninsula. Moment tensor solution reveal a thrust mechanism, which is in perfect concordance with the historic seismicity pattern. The event was caused by the convergence of the Arabian and Eurasian plates, that not only built up the impressive Zagros Mountains, but also lead to the formation of the Makran Subduction Zone. Relative plate motions there are as fast as 20 mm/yr in the central part. Continue reading “M6.3 earthquake rocks southwestern Iran, felt in Dubai, Abu Dhabi, Qatar, Bahrain”

Georadar on active (?) faults in Oman

I am currently at GUtech in Oman, a sister university of RWTH Aachen University, for teaching Geophysics and I spend most of the free time in the field with my colleague Gösta Hoffmann. On Friday we went to the Batinah area NW of Mascat to look for active faults. The Batinah is a plain of most likely Quaternary age, made up from the sediments delivered from the huge mountains in the south. Folded Tertiary limestones are cropping out close to the mountain range. Some of them are covered by Quaternary gravels, others aren’t. Continue reading “Georadar on active (?) faults in Oman”
