Ruth Amey, SENSE’s Leeds-based centre manager, has just published a new paper using satellite imagery to create high-resolution maps of ground surface elevation. This is then used to better inform estimates of hazard and risk due to earthquakes.
The paper focusses on Almaty in Kazakhstan. Almaty, like many cities around the world, it is located close to a number of active faults on which earthquakes can occur. There may also potentially be faults underneath the city that have been buried as Almaty has expanded and increased in population to approximately 2 million.
In the paper, the authors use Pleiades and SPOT stereo satellite imagery. This is optical satellite imagery of the same area taken from at least two different angles.
Then by using photogrammetric methods, the authors create high-resolution digital elevation models (DEMs). As the gif below shows, DEMs at very low resolution can pick out the outline of mountain ranges, but not much more than this. With Pleiades imagery, we can create DEMs of approximately 2m resolution, meaning we can pick out details in the city such as buildings and trees. This is the resolution needed to identify subtle changes in elevation in cities that may indicate there are active faults.
With these high-resolution DEMs, fieldwork and other literature, the authors identify and examine a potential active fault underneath Almaty city. The authors then use the Global Earthquake Model‘s Openquake Engine to calculate the hazard (ground shaking) and risk (damage and losses) to Almaty city.
The University of Leeds runs an annual open research festival called Be Curious, which aims to showcase how research at Leeds is making a world of difference to people’s lives. In 2021’s online extravaganza, SENSE students, academics and managers were involved in a whole host of events. This includes in the Be Curious LATES programme, making short videos and the headline act: Be Curious x Unlimited Space Agency: LIVE from the Space Shed. SENSE scientists were interviewed by Jon Spooner from the Unlimited Space Agency, and not forgetting Mini-Jon … You can watch the full event here, or below we’ve put the videos for each session.
Brrr… science in the coldest, windiest and most remote continent on Earth
Jane’s favourite memory of Antarctica was sitting on the edge of cliff looking out over the ocean after a long day of collecting samples; the sun was shining, the wind had dropped so it was warm (it does happen in Antarctica!). The sun was shining on the ice, the icebergs and tiny flakes of ice in the air. The sun was hitting these tiny flakes and made the whole world glittery. It was calm and tranquil, with no noise. Sounds beautiful.
Bryony went over Christmas, so got to experience the the whitest of white Christmasses you could imagine! On Christmas eve, they’d been digging snow pits ~2-3m deep to look at layers in the ice… which they turned it into a cave! They then slept in their snowcave overnight and woke up on christmas day, as it started snowing on their faces, in Antarctica. Amazing.
Watch their full interview here (hats and gloves not necessary!):
Build your own satellite model
SENSE student Sophie Durston led the audience through how to build your very own Aeolus satellite model. Aeolus is a European Space Agency (ESA) satellite, and the very first satellite used to measure wind. It was launched in 2018, and recently the measurements have been used to improve weather forecasts. Find out more fun facts from Sophie and SENSE manager Ruth Amey, as they make their own models in the video below.
With all the satellites she ‘made earlier’, we look forward to watching Sophie’s future career as a presenter of Blue Peter…! And can you make your satellite in 1 minute 16 seconds, like in SENSE student Phoebe Hudson‘s video?
Next, we blasted off with SENSE students Bryony Freer and Calum Hoad, who took us on a Tour of Earth from Space. We don’t want to give too much away… but highlights included stuck ships, retreating glaciers and even penguin poo.
Watch the video below for a tour of Earth as you’ve never seen it below, and you can follow along using this resource page.
The Earth from Inside Out
SENSE manager Dr. Ruth Amey and Ita Gonzalez discussed watching the Earth quake and volcanoes erupt, from Space. Ruth uses satellites that can see through clouds to watch the ground move centimetresor milimeters in earthquakes… using satellites that are orbiting at 693km above the Earth!
And they discuss not only earthquakes on Earth… but also on the moon and Mars. Where of course they aren’t earthquakes at all, but moonquakes and marsquakes.
How I hacked my way into Space
A very special session… look out for future Space Shed events to find out how Mini-Jon hacked his way into Space!
Q&A with Mini Jon and Dr Alice Bunn, the UK Space Agency’s former International Director
SENSE is delighted to be partly funded by the UK Space Agency (UKSA), and we really enjoyed hearing Jon interview Dr Alice Bunn, the former UKSA International Director.
Find out what it’s like to be the international director of a Space agency(!) in this video:

The students have landed
Twenty days after Be Curious x Unlimited Space Agency: LIVE from the Space Shed, the YouTube video has received over 560 views!
We’re over the moon at the success of this event, and so proud of the SENSE students involved in this – Bryony Freer, Sophie Durston, Calum Hoad, Morag Fotheringham, Phoebe Hudson for their interviews, talks, videos and practical activities; Emily Dowd and Lucy Wells for working behind the scenes on social media, and Bryony for coordinating the SENSE involvement.
Whilst not everyone struggles with their mental health as a PGR, a large proportion do. We are committed to creating safe spaces where our students can come together and not suffer alone.
Next month, PhD students at the University of Leeds in collaboration with SENSE bring you ‘Not another wellbeing workshop…’ with the aim of enabling open discussions about wellbeing and mental health in the Postgraduate Researchers (PGRs) community. 1 in 2 PhD students struggle with mental health during their PhD and a recent survey of PGRs in the Faculty of Environment at the University of Leeds showed that 85% of students surveyed reported their mental wellbeing to be moderately to severely affected in the past year. However, over 60% of those affected have not sought support for their mental health.
This workshop will share the resources available at the University and externally along with sharing the experiences of past and present PGRs through two panel discussions.
The first the panel will discuss their own experiences of struggles during their postgraduate research. You will have the opportunity to anomalously share your own experiences and concerns on our padlet walls (a virtual note board). The second panel will discuss tips and tricks that have helped them, and you will be again encouraged to use our padlet wall to contribute to this discussion and share your own ideas. The panel are not experts on mental health – they are your peers sitting on the virtual desk next to you! We hope that by discussing personal experiences in event created by PGRs for PGRs, we can start an important conversation in our PGR community that creates a happier, healthier and supportive peer network that we will all benefit from.
At the end of the discussion session, we have invited the University of Leeds Student Counselling and Wellbeing service to present the services and professional support that is available for you to access at any time. You can find information about these resources here at the University of Leeds, and here at the University of Edinburgh.
There will be virtual coffee breaks to have a breather and a good old chat (BYO virtual tea, coffee and cake strongly recommended!). Throughout the week following the event there will be a couple of opportunities to have coffee breaks to chat with some of the panellists about anything that may come up or if you just want to decompress over the rest of the week.
While we are aiming to provide a safe and supportive space for PGRs who have struggled with their mental health, this is also very much open to anyone who has not. It can be an opportunity to learn more about the issues your peers might be struggling with too, and how to best support them through some of the common challenges that are faced while doing a PhD. Through conversation with those of us who struggle more and less with these issues, we hope to help reduce some of the stigma associated with discussing these issues amongst PGRs.
This workshop is strictly for PGRs to aid open discussion of issues, which may not be achieved, with more senior staff present. Any key themes and anonymised statistics from polls etc. might be shared with management teams to help move towards more open discussions around mental health and the academic environment. Whilst the panel will be discussing their own personal struggles, this event is not a place to get individualised help for specific issues you may be dealing with, but we will direct you to places and people who can.
The event will run through zoom webinars and will not require you to disclose any of your personal details. We have used padlet walls to enable anonymity for all those attending and contributing their own experiences. Please remember to be kind with anything you post. During the event there may be polls used to gauge the feeling in the ‘virtual room’, but these will only show the stats output and no result will be traceable back to you.
Huge congratulations to SENSE student Nick Homer, for his successful application to the Alan Turing Institute Enrichment Scheme. Nick will be spending 9 months from March 2022, working part-time at the Alan Turing Institute in London.
The Turing Enrichment scheme offers students currently enrolled on a doctoral programme at a UK university the opportunity to spend up to 12 months at the Turing in London. The Enrichment scheme has been designed to give students undertaking a PhD the opportunity to support and enhance their current research by accessing the facilities and opportunities available at The Alan Turing Institute and its partners. Students usually join in their second or third years of a typical doctorate, to further the work they are undertaking for their research project and support the completion of the PhD.
Applications for 2021 have now closed, but if you’re interested in applying for next year you can view this information session on Turing’s YouTube channel.
Next week, SENSE students and staff will be joining the Leeds University ‘BeCurious’ event, a 10-day festival of science showcasing how research makes a difference to people’s lives. ‘BeCurious’ is the university’s annual open research event, and this year focuses on the United Nations’ Sustainable Development Goals (SDGs).

Huge congratulations to SENSE student Max Lowe for publishing his first paper, from his Msc thesis, in EGU journal Solid Earth.
Max says –
This study estimates the gravitational contribution of former tectonic plates subducted into Earth’s interior (slabs) to the Alpine gravity field. Different seismological studies identified various slab segments beneath the Alpine mountain belt within Earth’s upper mantle. However, the position, geometry and extend of those slabs vary strongly in those studies. In addition, some recent gravity models do not account for such heterogeneities in the Earth’s mantle.
Here, the sensitivity of gravity measurements to variation in slab position, geometries and volume is tested. Therefore, two competing slab configurations are defined based on seismological findings. In addition, the gravity contribution caused by slab segments within the Earth’s mantle is estimated by forward calculating density distributions based on three different modelling approaches. a) direct conversion of seismic velocities to density distributions, b) density variation based on predefined slab configurations and c) calculating density distributions based on geophysical and petrological modelling taking rock composition, temperature and pressure into consideration.
We find that the gravity signal caused by the slab segments is sharp and can be separated for the different slab segments for the gravity field measured at near surface height. At satellite altitude the contribution of different slab segments cannot be separated anymore. We showed that slab segments can contribute up to 40 mGal to the Alpine gravity field. This is significant and demonstrates that future studies should account for densities variation within the mantle caused by slabs to provide a meaningful representation of the geodynamic complex Alpine area.
SENSE are delighted to have been nominated for a Leeds Partnership Award this year for our work on improving equality, diversity and inclusion in recruitment procedure.
The SENSE team were nominated for going ‘above and beyond’ in their work on improving equality and inclusion in SENSE’s postgraduate recruitment procedure, and for continually pushing this agenda in the School of Earth and Environment and across the University.
Paid Summer Internships for Undergraduate Students – deadline16th May 2021
