The Earthquake/Seismic Activity Log

It makes me cringe a little to say it, but the world has been relatively quiet, in terms of large quakes. The smaller ones, however, are all over the map. In the U.S. there have been small quakes in Arkansas, Texas, Tennessee, and the "Greater New York/New Jersey area" (something not seen very often on the logs).

The Loyalty Islands have already had 10 aftershocks that were 5.0 or larger, and one that was 4.9. This area is full of volcanoes.

NOTE: unlike the other subduction zones on the ring of fire, in the case of the Loyalty Islands, it is the Australian plate getting shoved under the Pacific plate. It is usually the Pacific plate that is subducted, so this is a rarity (the geology, not the quakes).

UPDATE 19:01 UTC : Dianne Hambrook in Port Vila, Vanuatu experience report : “We definitely felt that one! The 7.1 in the Loyalty Islands (it didn’t seem that strong but it was quite a long way away). A kind of gentle, rocking and rolling motion that went on for a long time.

We were watching a play and the actors never missed a beat. They carried on performing as if nothing was happening. Impressively professional. Several members of the audience vacated the theatre for the duration though”.

The reports I read said “potentially affecting zero people”. Right!

UPDATE 11:15 UTC : Seismological bureaus have lowered the magnitude from the initial 7.1 to 6.8, seemingly nothing but in earthquake terms a big difference in energy.

UPDATE 11:13 UTC : As expected the first strong aftershock (5.7 magnitude) occurred a little while ago. There might be some very strong aftershocks to follow, but the aftershocks will be normally harmless and will be gradually winding down from very strong, to strong, to moderate. We will publish the +4.5 aftershocks in our daily earthquake overview, just like we do for the Japan Tohoku earthquake.

UPDATE 10:48 UTC : A reader living in Noumea, New Caledonia reports : I was sitting at a table at an outdoor restaurant and felt weak shaking. MMI II to III

UPDATE 10:27 UTC : Here is the USGS description of the tectonic elements that triggered a similar earthquake in the same area in December 2010. The forces that generated today’s earthquake are the same :
The Vanuatu (New Hebrides trench) earthquake of December 25, 2010, occurred as the result of normal-faulting within the Australia plate, in the region of the boundary between the Australia plate and the Pacific plate. In the epicentral region of the earthquake, the Australia plate moves east-northeast relative to the Pacific plate with a velocity of about 8 cm/yr.

The Australia plate subducts beneath the Pacific plate at the New Hebrides trench and is seismically active northeast of the epicenter of the December 25 earthquake to a depth of 300 km.
The stresses that generated the earthquake result from the bending of the Australia plate as it subducts beneath the Pacific plate.

The New Hebrides arc region of the Australia/New Hebrides plate-boundary experiences numerous strong earthquakes.

In the past quarter century, the thousand kilometer section of the arc centered on the epicenter of the December 25 earthquake has produced 19 earthquakes of magnitude 7 or greater, the largest having magnitude 7.7.

The western margin of the Pacific plate that lies to the east of the New Hebrides trench is commonly viewed as being subdivided into several microplates that move with respect to each other at rates of a few cm/yr. http://earthquake-report.com/2011/05/10/massive-earthquake-between-new-caledonia-and-vanuatu/

Strong earthquake near Lorca and Murcia, Spain

Recap of May 11, the day of the Lorca earthquake. Earthquake-Report.com was alerted by a weak but shallow earthquake shortly after 5 PM. Every day tens of earthquakes of this magnitude are occurring all over the world, so nothing special here. Shortly after the first shaking we mentioned already the possibility of cracks in walls. While checking local reports we detected some light damage in the Lorca area and we also got a notice that an elderly institute had to be evacuated. 2 hours later a much stronger and also shallow 5.2 aftershock occurred. It was immediately clear to us that this last quake increased the potential for damage and injuries a lot. Soon thereafter the first reports on damage to private houses, municipality buildings and historic places were published. Authorities did all what they could to help the unfortunate Lorca people. Stay tuned to Earthquake-Report.com as we will also give other news-facts the coming hours.

Understanding the Lorca, Spain May 11 2011 earthquake


The southeastern Spain earthquake of 11 May, 2011, occurred within the plate boundary region that separates the Eurasia and Africa (Nubia) plates. At the longitude of the earthquake, the Africa plate moves NW with respect to the Eurasia plate with a velocity of 6 mm/yr.



Earthquakes in different parts of the plate-boundary region separating Africa and Eurasia may occur as the result of strike-slip or normal faulting, in addition to the reverse/thrust faulting that is expected as the most direct consequence of the convergence of two major plates. The diversity of faulting styles over the plate-boundary region may reflect the motions of crustal blocks that are situated within the broader plate-boundary zone and that move slowly relative to one another to accommodate the NW/SE convergence of the major plates.


The epicenter of the 11 May earthquake is situated near a major fault, the Alhama de Murcia fault. However, significant field work in the epicentral region of the earthquake will be necessary to confidently determine if the earthquake occurred on a segment of the Alhama de Murcia fault or on a nearby fault.

In recent decades, the larger shallow-focus shocks of southeastern Spain have had magnitudes of about 5.

Shocks of this size occurred near the epicenter of the 11 May earthquake in February 1999 and August 2002. The distributions of damage associated with several shocks that occurred before the twentieth century imply that these shocks had magnitudes in the 6.5-7 range.

Iberia and the Mahgreb also experience occasional deep-focus earthquakes of magnitude greater than 6 that occur at depths of over 600 km in lithosphere that was subducted along the plate boundary millions of years ago.

All too real and surreal.

Unreinforced masonry. People need to be warned. The quake was a 5.2. Granted it was shallow and near a populated area, but it was still a 5.2.

Around here, people are required to give warning. All of the shops like this are within short walking distance from my office (NOT masonry). We are partially on stilts, however.
