Special Session at SSA2017 in Denver on Toppled and Rotated Objects

A special session on Toppled and Rotated Objects in Recent, Historic, and Prehistoric Earthquakes will be held during the upcoming 2017 Annual Meeting of the Seismological Society of America in Denver, Colorado from 18-20 April 2017.  Session Chairs will be Klaus-G. Hinzen and Rasool Anooshehpoor.

The main purpose of the session is to bring together researchers with diverse backgrounds (e.g., seismology, engineering, history, heritage conservation) who are interested in the behavior of objects, monuments, or simple structures during earthquakes and the stories which deformed, rotated or toppled objects can tell. The session will cover all aspects of toppled or rotated objects or simple structures which have suffered heavy deformation or damage during earthquakes. Topics will include: (1) observations, (2) documentation, (3) model building, (4) restoration, (5) mapping, and (6) correlation with geology.

Recent earthquake research has postulated correlation between the reaction of objects (monuments, columns, tombstones, etc.) and the seismic source in addition to local effects due to geological site conditions. As the laws of physics are time invariant, knowledge gained in reconnaissance surveys from well-studied instrumental earthquakes can reveal information about ground motions during historical and prehistorical earthquakes. Particular interest will be directed to man-made structures; however, due to similarities of the techniques used to study precariously balanced rocks and speleothems, contributions from these fields are also welcome.

The deadline for all proposed presentations, invited or otherwise, is 5 pm PST January 11, 2016.  All abstracts must be submitted by the deadline. Submitting abstracts through the online submission system only (There is a submission fee of $80 for regular attendees, $40 for students).


There are lots of other interesting sessions on earthquake geology, paleoseismology and related topics at the SSA meeting, make sure to check the full programme: http://meetings.seismosoc.org/special-sessions/

Postdoctoral fellowship in coastal paleoseismology/Quaternary environmental change in Belgium

The Royal Belgian Institute of Natural Sciences – Geological Survey of Belgium, invites applicants for a research fellowship (postdoctoral level) in coastal paleoseismology/Quaternary environmental change. It will be a 1.5 year contract (January/February 2017- June 2018). Here’s the job advert: Continue reading “Postdoctoral fellowship in coastal paleoseismology/Quaternary environmental change in Belgium”

8th PATA Days in New Zealand will be postponed to November 2017

Dear friends and colleagues,

We are very sorry to announce that the 8th PATA Days in New Zealand can not take place in April 2017. The meeting has to be postponed to November 2017. The Kaikoura Earthquake has not only shaken up the entire country, but also disrupted the organisation of the PATA Days. All NZ earthquake geologists are currently in the field and they will have to deal with the EQ aftermath for the next couple of months. It is just technically impossible to organise the meeting in April under these circumstances. It’s also going to be really hard to get the NZ sponsorship that we counted on, as funds from places like the Earthquake Commission will be diverted to the Kaikoura EQ response & follow up research.

Of course, the field trip plans will also have to change completely. In November 2017 we will be able to see some of the most stunning effects of the Kaikoura Earthquake. In April, many roads will still be shut and many landowners will still be recovering and may not be amenable to curious scientists. By November next year, if we can incorporate some community outreach, then it will be much more appropriate to bring a field trip through the impacted area – pending open roads.

We are very sorry for any inconvenience this may cause and we hope for your understanding. Currently the NZ organising team is working hard to fix new dates and locations. The official PATA website will be updated as soon as they’re back in office for a couple of hours.

On behalf of the organisers,

Christoph & the EGSHaz team

Special Issue in Annals of Geophysics on the Amatrice earthquakes

Annals of Geophysics has just published a special issue on the devastating Amatrice Earthquake series in Central Italy: Vol 59, Fast Track 5 (2016): The Amatrice seismic sequence: preliminary data and results.

The special issue, edited by Marco Anzidei and Silvia Pondrelli, contains lots of field reports, first assessments, and plenty of primary data. Plus, it’s all OPEN ACCESS! Continue reading “Special Issue in Annals of Geophysics on the Amatrice earthquakes”

Preliminary Map of Co-Seismic Landslides for the M 7.8 Kaikoura, New Zealand Earthquake

The M7.8 Kaikoura Earthquake in New Zealand produced one of the most complex ruptures ever observed, involving many different faults. Earthquake environmental effects include up to 10 m offset at the Kekerengu Fault, secondary ruptures, a tsunami, coseismic uplift, landslides and rockfalls, liquefaction, and maybe even earthquake lights. Lots of blogs and websites provide coverage on this earthquake, e.g. Geonet, the Landslide Blog, and The Trembling Earth. Our colleagues from the Research Group on Earthquake Geology in Greece worked on the landslides that happened during the earthquake. George Papathanassiou sent me the link to their Preliminary Map of Co-Seismic Landslides for the M 7.8 Kaikoura, New Zealand Earthquake.

Earthquakes in Italy: first InSAR data and field reconnaissance

On 26 October two shallow normal faulting earthquakes occurred in Central Italy, very close to the epicentre of the Amatrice Earthquake from earlier this year. The first quake reached a magnitude of M5.5 and was followed by a M6.1 just two hours later. The events caused serious damage (see here for a video and some images), but luckily only one person died as most people had left their houses after the first moderate shock. This could have turned out much worse. Apparently the quakes at least partly filled the gap between the 1997 Colfiorito events and the 2016 Amatrice Earthquake.

Session on paleoseismology at the TSG-VMSG-BGA Joint Assembly (Liverpool, 4-6 Jan 2017)

The first joint assembly of the Tectonic Studies Group (TSG), Volcanic and Magmatic Studies Group (VMSG), and British Geophysical Association (BGA) will be held at the University of Liverpool from 4-6 January, 2017. Among the many interesting sessions the following one will be of special interest for … well … us:
S.12 – Earthquakes, palaeoseismology, and rates of fault slip: from milliseconds to millions of years. The session is chaired by Laura Gregory, Ed Garett, and Luke Wedmore, deadline for abstracts is 5 November.
