Cambridge engineer to co-lead earthquake reconnaissance mission to Turkey
Professor Emily So, Director of the Cambridge University Centre for Risk in the Built Environment (CURBE) will be co-leading a UK team of engineers, seismologists and geologists on a reconnaissance mission to Turkey, to undertake post-earthquake assessments and uncover the causes of this natural disaster.
Organised by The Earthquake Engineering Field Investigation Team (EEFIT), Professor So will co-lead the mission alongside Yasemin Didem Aktas from UCL and will work closely to support Turkish colleagues and officials. The EEFIT is a joint venture between industry and universities, conducting field investigations following major earthquakes.
The earthquake struck south-eastern Turkey and neighbouring Syria on Monday 6 Feb, registering a 7.8 magnitude quake. It is Turkey's worst earthquake since 1939, impacting 13.4 million people living in the 10 provinces hit by it. At the time of writing, the death toll had climbed to more than 36,000, with the United Nations warning that the final number may double.
The reconnaissance mission will carry out detailed technical evaluations of the performance of structures, foundations, civil engineering works and industrial plants within the affected regions. They will also assess the effectiveness of earthquake protection methods, study disaster management procedures and investigate the socio-economic effects of the earthquake.
Professor Emily So says: “Last week’s earthquake has caused untold damage and suffering for up to 15% of Turkey’s population. This mission will enable us to observe the damage and the effects of the earthquake first-hand to identify the main lessons that can be learnt. The EEFIT mission is our opportunity to observe the real performances of buildings and question why they have collapsed and why they have not withstood the earthquake. These lessons are key to help direct future research, and prioritise actions for change.”
Professor So is a chartered civil engineer and Director of the Cambridge University Centre for Risk in the Built Environment (CURBE). Her main area of interest is in assessing and managing urban risk and resilience. She has actively engaged with earthquake‐affected communities in different parts of the world, focusing on applying her work towards making real‐ world improvements in seismic safety.
Saving lives from earthquakes is a priority and motivates her research. Her area of specialty is casualty estimation in earthquake loss modelling and her research has led to improved understanding of the relationship between deaths and injuries following earthquakes.
Recognised as an expert in the field, Professor So sits on the Scientific Advisory Group for Emergencies (SAGE) providing valuable and timely scientific and technical advice to support the UK Government’s Cabinet Office Briefing Room (COBR).
Professor So is a Fellow and Admissions Tutor for Recruitment at Magdalene College, Director of Studies in Architecture at Magdalene and St Edmund’s College and a Director of Cambridge Architectural Research Ltd.

Interfering in big decisions friends and family take could violate a crucial moral right, philosopher argues
If you’ve told an adult friend or family member that they should not take a job, not date someone, not try skydiving or not move abroad, you may have violated a crucial moral right to ‘revelatory autonomy’ and ‘self-authorship’, according to a philosopher at Christ’s College, Cambridge.
Dr Farbod Akhlaghi’s study, published in the journal Analysis, is the first of its kind to suggest that we have a moral right to ‘revelatory autonomy’, that is the right to discover for ourselves who we’ll become as a result of making ‘transformative choices’, choices to have experiences that teach us what that experience will be like for us whilst also changing our core preferences, values and desires.
Dr Akhlaghi says: “The ability to see that the person we’ve become is the product of decisions that we made for ourselves is very important.
“I’m not telling people what to do. I’m just highlighting part of what is morally at stake in these very common interactions and trying to develop a framework for us to understand them. I hope some may find this helpful, as these will always be difficult moments for all of us.”
Traditionally, philosophers interested in ‘transformative experiences’ have focused on the decision-maker not on the people who are in a position to influence that person’s choices. But Dr Akhlaghi thinks that these neglected interactions present ‘an urgent ethical challenge’:
“There are lots of different reasons why we might seek to intervene – some selfish, others well meaning – but whatever our motivation, we can cause significant harm, including to the people we love most.”
While Akhlaghi accepts that advice can be offered without crossing the moral line, he warns that it is all too easy to slip into various forms of interference, such as forcing, coercing, manipulating or even ‘rationally persuading’ someone away from a transformative choice, in ways that may violate their right to revelatory autonomy.
Akhlaghi says: “Rational persuasion is probably the most common form of interference. Giving, when asked, factual information about a choice that you have knowledge about and the other person does not, can be justified. But while rational persuasion respects someone’s ability to reason, even this form of engagement can involve disrespecting their autonomous self-authorship.
For example, Akhlaghi continues: “Offering reasons, arguments or evidence as if one is in a privileged position with respect to what the other person’s experience would be like for them disrespects their moral right to revelatory autonomy.”
Initially inspired to consider this area of moral philosophy by personal experiences, Dr Akhlaghi examines and rejects a number of other conditions under which it could be argued that trying to prevent someone from making transformative choices is morally justified.
For example
Dissuading someone from becoming a parent because you think parenthood would make their life worse is problematic because becoming a parent is a positive experience for some and not for others, and no one can know that outcome in advance, even if the person doing the dissuading has experienced being a parent themselves.
A different example in the study relates to dissuading someone from making a career change that involves a big pay cut because you think that they would struggle to afford their expensive tastes. This is just as problematic, Akhlaghi says, because:
“We can only know what the future person’s interests are and whether their present interests will be fulfilled after a transformative choice has been made.”
“The person who changes job might manage to afford their expensive tastes and we don’t even know if that future person would still have these tastes. This highlights another problem – whose interests matter morally when trying to justify interfering: those of the present or the future person?”
Is it ever right to interfere?
“It is only permissible to interfere to try to prevent a transformative choice,” Akhlaghi argues “if someone’s right to revelatory autonomy is outweighed by competing moral considerations.”
A would-be killer’s right to revelatory autonomy is, for instance, plausibly outweighed by the wrongness of killing others solely to discover who they would become by doing so. Equally, protecting a friend from gratuitous self-mutilation would plausibly outweigh their right to autonomously discover what it would be like to harm themselves in this way.
Akhlaghi suggests that the more likely it is that a choice will affect someone’s ‘core preferences, identity and values’, the stronger the moral reasons would need to be to justify interfering in their decision. For instance, interfering in someone’s decision to go to university or not, would require far stronger moral reasons than them choosing whether to eat a cheeseburger or not.
Finally, Akhlaghi clarifies that his study concerns voluntary choices to have ‘transformative experiences.’ Some such experiences are instead either the unintended consequences of something we did, or ones we are forced into as, for example, children might be by a divorce. These raise different but related problems he hopes to explore in future work.

We have a moral duty to allow others to make ‘transformative choices’ such as changing careers, migrating and having children, a new study argues. This duty can be outweighed by competing moral considerations such as preventing murder but in many cases we should interfere with far greater caution.

Pedestrians choose healthy obstacles over boring pavements, study finds
Millions of people in the UK are failing to meet recommended targets for physical activity. Exercising “on the go” is key to changing this but while walking along a pavement is better than nothing it causes no significant increase in heart rate so only qualifies as mild exercise. Walking also fails to significantly improve balance or bone density, unless it includes jumping, balancing, and stepping down.
But would adults opt for such ‘fun’ routes if given the choice? A University of Cambridge-led study published today in the journal Landscape Research suggests that with the right design, most would.
Previous research on ‘healthy route choices’ has focused on people’s likelihood of walking instead of using transport. But this study examined how likely people are to pick a more challenging route over a conventional one and which design characteristics influenced their choices.
Lead author, Anna Boldina, from the University of Cambridge’s Department of Architecture, said: “Even when the increase in level and extent of activity level is modest, when millions of people are using cityscapes every day, those differences can have a major positive impact on public health.”
“Our findings show that pedestrians can be nudged into a wider range of physical activities through minor changes to the urban landscape. We want to help policy makers and designers to make modifications that will improve physical health and wellbeing.”
Boldina began this research after moving from Coimbra in Portugal – where she found herself climbing hills and ancient walls – to London, which she found far less physically challenging.
Working with Dr Paul Hanel from the Department of Psychology at the University of Essex, and Prof. Koen Steemers from Cambridge, Boldina invited almost 600 UK residents to compare photorealistic images of challenging routes – variously incorporating steppingstones, balancing beams, and high steps – with conventional pavements.
Participants were shown images of challenging and conventional tarmac routes and asked which route they would choose. The researchers tested out a range of encouraging / discouraging parameters in different scenarios, including crossing water, shortcuts, unusual sculptures and the presence / absence of a handrail and other people. Participants were asked to score how challenging they thought the route would be from 1 (as easy as walking on level tarmac) to 7 (I would not be able to do it).
Eighty per cent of the study’s participants opted for a challenging route in at least one of the scenarios, depending on perceived level of difficulty and design characteristics. Where a challenging option was shorter than a conventional route, this increased the likelihood of being chosen by 10%. The presence of handrails achieved a 12% rise.
Importance for health
The WHO and NHS recommend at least 150 minutes of ‘moderate’ or 75 minutes of ‘vigorous’ activity spread over a week, including a variety of activities aimed at enhancing bones, muscles, and agility to stay healthy. In addition, adults over 65 are advised to perform strength, flexibility, and balance exercises.
Boldina said: “The human body is a very complex machine that needs a lot of things to keep working effectively. Cycling and swimming are great for your heart and for your leg muscles but do very little for your bone density.”
“To improve cardiovascular health, bone density and balance all at once, we need to add a wider range of exercises into our routine daily walks.”
Psychology of choice
Co-author Dr Paul Hanel said: “Children don’t need much encouragement to try out a balance beam but we wanted to see how adults would respond, and then identify design modifications which made them more likely to choose a challenging route.”
“We found that while embarrassment, anxiety, caution and peer pressure can put some adults off, the vast majority of people can be persuaded to take a more challenging route by paying careful attention to design, safety, difficulty level, location and signage.”
The proportion of participants who were willing to pick a more challenging route varied from 14% for a particular balance beam route to 78% for a route involving wide, low stepping stones and a log with a handrail. The least intimidating routes were found to be those with wide, steady-looking balancing beams and wide steppingstones, especially with the presence of handrails.
The researchers suggest that routes that incorporate more difficult challenges, such as obstacle courses and narrow balancing beams, should be placed in areas more likely to be frequented by younger users.
The participants expressed a range of reasons for picking challenging routes. Unsurprisingly, the study found that challenging routes which also acted as short cuts appealed. Up to 55% of participants chose such routes. The researchers also found that the design of pavements, lighting and flowerbeds, as well as signage helped to nudge participants to choose more challenging routes. Many participants (40%) said the sight of other people taking a challenging route encouraged them to do the same.
The participants who picked conventional routes often had concerns about safety but the introduction of safety measures, such as handrails, increased uptake of some routes. Handrails next to one steppingstones route increased uptake by 12%.
To test whether tendency to choose challenging routes was linked to demographic and personality factors, participants were asked to answer questions about their age, gender, habits, health, occupation, and personality traits (such as sensation seeking or general anxiety).
The researchers found that people of all levels of activity are equally likely to pick a challenging route. But for the most difficult routes, participants who regularly engaged in strength and balancing exercises were more likely to choose them.
Older participants were as supportive of the concept as younger ones but were less likely to opt for the more challenging routes for themselves. Nevertheless, across all age groups, only a small percentage of participants said they would avoid adventurous options completely.
The study applies the idea of “Choice Architecture” (making good choices easier and less beneficial choices harder) plus “Fun theory”, a strategy whereby physical activity is made more exciting; as well as some of the key principles of persuasion: social proof, liking, authority, and consistency.
Future work
The researchers hope to run experiments in physical test sites to see how intentions convert into behaviour, and to measure how changes in habits improve health. In the meantime, Boldina continues to present her findings to policy makers.
Critics might question the affordability and cost effectiveness of introducing ‘Active landscape routes’ in the current economic environment.
In response, the researchers argue that installing stepping stones in a turfed area can be cheaper than laying and maintaining conventional tarmac pavements. They also point out that these measures could save governments far greater sums by reducing demand for health care related to lack of exercise.
