Two Large Earthquakes in Mexico
On Septmeber 6, the 8.1-magnitude earthquake in Mexico, Chipas Earthquake, struck off the country's southern coast and affected 1.5 million people, with more than 90 casualty and 40,000 homes damaged. A dozen of strong aftershocks measuring above 5.0 in magnitude continue to affected the devastated areas. One September 19 , the 7.1-magnitude earhquake, 2017 Central Mexico Earthquake, hit the country of Mexico again at the south of the city of Puebla. Due to the earthquake-related building collapses more than 350 fatalities and 6,000 injuries have been reported. The IAEE officers offer our heartfelt sympathy for those affected by the earthquake in Mexico.

Report from the 16th World Conference of Earthquake Engineering, Santiago, Chile
The 16th World Conference of Earthquake Engineering was held in Santiago, in Chile,from January 9th to 13th. It hosted scientists and engineers working in the field of earthquake engineering all over the world, who contributed with more than 2000 scientific papers. A great variety of topics was presented, among which structural engineering, performance-based design, lifeline systems, design criteria, social and economic issues, and lessons from recent earthquakes. The 16th WCEE was a great occasion to establish new collaborations and to enforce the existing synergies inside the international scientific community, in order to spread the developments reached by the scientific research.
The IAEE is pleased to announce that the 17th WCEE will be hosted in Sendai, Japan, from September 14th to 18th 2020, and it is confident that it will provide another important chance of international collaborations.

The Passing of Nigel Priestley

One of earthquake engineering's leading lights of the past several decades, Nigel Priestley, has passed away. The notice from the New Zealand Society for Earthquake Engineering is reproduced here. It is with deep sadness that I inform you Professor Nigel Priestley passed away peacefully on Tuesday December 23, 2014 in Christchurch, surrounded by his wife and children, after a long battle with cancer. Nigel revolutionised the design of structures to resist earthquakes and made everlasting impact on the higher education for earthquake engineers in NZ, US and Europe. Nigel received numerous honours for his immense contribution to the science and art of Earthquake engineering. Amongst these, it include honorary doctorates from ETH, Zurich and Cujo Argentina; Nigel was a Distinguished Fellow of IPENZ, Fellow of the Royal Society of New Zealand, an Officer of the New Zealand Order of Merit (ONZM), and a Life Member and a past President of the Society (1985-1986).

Remembering The Great East Japan Earthquake of March 11, 2011

It has now been two years since the occurrence of what has turned out to be one of the deadliest and most costly natural disasters ever witnessed in the world. The M9 mega-event that shook the northeastern seaboard of Honshu Island, where the nearest major city is Sendai, ranks among the largest seismic events that have been recorded. The earthquake unleashed a major tsunami that swept across many smaller fishing settlements along the Tohoku coastline, and exacted a human loss toll that stands in excess of 18 000 with many injured. A series of seemingly unlikely equipment failures at the Fukushima Daiichi nuclear plant led to multiple meltdowns and releases of radioactive materials into the environment following the earthquake and tsunami.

The scale of the disaster beggars description in terms also of economic losses. While performance of building systems, railway networks and early warning equipment for lifelines was good, many images of death and destruction brought by the tsunami were etched into the memory of everyone in the world. The Japanese people bore the tragedy with fortitude, and have gained the respect of other countries that must live within the shadow of the seismic threat because of the many individual tales of communal spirit and selfless solidarity.

This disaster must serve as a call for sustained vigilance and unflagging preparedness to protect lives and assets against the seismic hazard. The Hyogo Framework for Action (HFA) against natural disasters and their harmful effects was crafted in 2005 in Japan ten years after the Kobe earthquake to serve as the blueprint for risk reduction policies that governments must adopt and enforce. The International Association for Earthquake Engineering (IAEE) was among professional organizations that contributed to the preparation of HFA, and through its member national organizations, has been among the principal mechanisms for implementing the guiding principles that it has outlined.

We respectfully commemorate the memory of victims of the March 11, 2011 Japan earthquake with bowed heads, and pledge to pursue the objectives of IAEE in ensuring a safer world for all those who stand in danger of the seismic peril.

A Tribute for Nicholas N. Ambraseys, Honorary Member, by Edmund Booth

Nicholas Neocles Ambraseys (1929-2012) was one of the towering figures of engineering seismology, who played a key role in the development  of the discipline for more than half a century - from before the foundation of the IAEE in 1963 (he attended the committee meetings in 1960 that led to its establishment) right up to the time of his death at his London home on 28th December. [move page]

More than 30 national organizations have endorsed the IAEE declaration on the sentencing of six scientists and one public administrator in Italy over accusations of having made a falsely reassuring statement before the L'Aquila Earthquake in 2009.

National organizations from the following countries have endorsed to the IAEE declaration.

Algeria, Argentina, Australia, Austria, Bangladesh, Canada, Chile, China, Colombia, Costa Rica, Croatia, France, Germany, Greece, Israel, Japan, Korea, Macedonia, Mexico, Nepal, New Zealand, Norway, Peru, Portugal, Romania, Russia, Singapore, Spain, Switzerland, Chinese Taiwan, Thailand, Turkey, Ukraine, USA and Venezuela

Declaration by the International Association for Earthquake Engineering on the Sentencing of Seven Scientists in Italy Over Accusations of Having Made a Falsely Reassuring Statement Before the L'Aquila Earthquake in 2009

hat seven scientists who were members of the National Commission for the Forecast and Prevention of Major Risks have been sentenced to prison terms for having provided "inaccurate, incomplete and contradictory" information about the danger of the minor tremors felt ahead of 6 April 2009 M6.3 earthquake, leading to the deaths of some 300 persons in and around the historic town of L'Aquila in central Italy.

While we have not examined the wording of the court's decision we must take a stand on what we believe is a flawed judgment that might have a negative impact for the future. Earthquake science is not a magical tool that allows anyone to state with any degree of credible reliability when and where an earthquake with a prescribed size will occur because earthquake occurrence does not conform to a simple and coherent pattern. The interpretation of minor foreshocks to state whether they herald a major earthquake to follow has yet never been done, except in the imagination of publicity seekers with no scientific credentials or on account of pure coincidence. The seven defendants are all well known in their respective professional fields, and enjoy the respect of their peers. We feel that justice has been poorly served, and a dangerous precedent has been established with the verdict. No responsible scientist will henceforth dare to risk his or her professional reputation (not to mention personal well-being) by interpreting signals of activity from volcanoes or possible effects of hurricanes. Forces of nature usually do not lend themselves to easy forecasts, and most are inherently unpredictable.

The communication of risk to the public in a way that it can be easily understood is one of the most difficult challenges facing science and technology. The loss of life that occurred in L'Acquila was tragic and regrettable, but that is attributable to many other causes besides the statement undersigned by the defendants,and the variability of the ground motions that attacked those buildings. The aftermath must not be allowed to turn into a spectacle calling for false culprits to punish in the interest of appeasing the public outrage. Instead, we must draw the right lessons so that there will be no victims in the future in this type of a preventable disaster.
