The “Great 1117 Veronese Earthquake” was one of the strongest events that hit Northern Italy in historical times. Many aspects of this earthquake are still debated, but archaeological sources, historical archives, and geological records can help to better understand what had happened near Verona 900 years ago. On 20 January, 2017, a conference on the 1117 Veronese Earthquake took place in Venice, bringing together archaeologists, historians and earth scientists. The presentations were given in Italian, but Paolo Forlin from the Armedea project provides an English summary of the meeting. Read his highly interesting article here. more

If you are interested in visiting the epicentral areas of the recent earthquakes in the Central Apennines, Italy, this is your chance: A four days field trip will be held from 19-22 July, 2017, led by researchers who have studied the earthquake effects in detail. The trip focusses on the fault system that ruptured during the 1997 Umbria Marche, 2009 L’Aquila, and 2016 Norcia events. The trip is organised by scientists from Italy, France, UK, and Greece, and supported by a number of universities, state agencies, and INQUA, with the Università di Camerino as the main coordinator.
More information will be published soon. more

I wish you a successful and wonderful new year 2017! May you find impressive faults and good outcrops, may your trenches always be in the right place, and may your samples return good results. If 2017 brings you something that would be of interest to the paleoseismicity.org community, please let us know. In the mean time, enjoy those reads: more

Richard Styron has released a new, improved version of his Global CMT viewer webmap. The earthquake data are from globalcmt.org, updated every four hours, and colour-coded by depth (purple to yellow = shallow to deep). The tool also displays a number of major faults from the ATA and HimaTibetMap databases. This webmap is a fast and easy way to find interesting earthquakes and to explore global seismicity. Plus, it’s a beautiful map. Thanks Richard for that great application!

A continuous flow of images from the New Zealand earthquake reaches the earthquake geology community, and we’re probably all amazed by the coseismic offsets and other earthquake effects. However, the flow of papers on paleoseismology, tsunami, and active tectonics also does not stop and here is my digest for December. Enjoy reading!
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

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! more

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. more
