Multi-Hazard Risk Assessment

Online course Multi-hazard risk assessment

Go to registration!

Owing to increased vulnerability and climatic extremes, we are faced with the rapidly growing impact of disasters worldwide. There is an urgent need to incorporate the concepts of disaster risk management into planning, sustainable development and environmental impact assessment. Disaster risk management requires the assessment of risk, which is a multidisciplinary endeavour.

The course explains how to conduct a risk assessment using spatial information on hazards, elements at risk and vulnerability with the aid of GIS and remote sensing, and how this information can be used in risk management, with a focus on urban areas.

For whom is the course relevant?

This course is designed for all those who have to carry out risk assessment and require knowledge and skills in using a GIS to handle the necessary the procedures, such as professionals working in governmental and non-governmental organizations, planners, engineers, architects, geographers, environmental specialists and university teachers. Some basic background in GIS is desirable, although not strictly necessary as the course follows a step-by-step approach that enables participants to rapidly acquire the basic skills in handling GIS software.

What will be achieved?

The course will guide participants through the entire process of risk assessment, on the basis of a case study of a city exposed to multiple hazards. At the end of this course, you will be able to:

  • understand the concepts of hazard assessment, elements-at-risk mapping, vulnerability assessment and risk assessment
  • formulate the spatial data requirements for risk assessment
  • use GIS to generate an elements-at-risk database
  • apply various methods for vulnerability assessment
  • generate risk maps using qualitative and quantitative methods
  • understand how risk assessment is used in risk reduction and disaster preparedness.

What is the course content?

The course is composed of a number of sessions. Each session has a PowerPoint presentation and a document introducing the session topic. Each session also has exercises and assignments, including maps or materials to be handed in. The course is based on a study load of one module of three weeks (5 ECTs), which is offered in online form over a period of six weeks. Below is a summary of the sessions and detailed content.

Multiple choice exam

Why choose this course?

The course has been designed over a long period of time and has been tested many times in different countries. It is based on a course book with assignments and an exercise book with GIS exercises. Active interaction with lecturers and fellow students takes place via internet. The general approach of the course is task-based learning that blends theory and practice. The study load is 20 to 24 hours per week. 

About your diploma

Upon successful completion of this course you will receive a Certificate which will include the name of the course.

Along with your Certificate you will receive a Course Record providing all the subjects studied as part of the course. It states: the course code, subject, ECTS credits, exam date, location and the mark awarded.

If you decide to follow a full Postgraduate or Master's course at ITC, and after approval of the Examination Board, you will be exempted from the course(s) you followed successfully as an online course.

Admission requirements

Academic level and background

Applicants for an online course should have a Bachelor degree or equivalent from a recognised university in a discipline related to the course, preferably combined with working experience in a relevant field.


The faculty accepts transcripts, degrees and diplomas in the following languages: Dutch, English, German, French and Spanish. It is at the discretion of the faculty to require additional English translations of all documents in other languages as well.

Language skills

Success in your studies requires a high level of English proficiency. Therefore, prospective students with an international (other than Dutch) degree must meet the English language requirement. As proof that you meet this requirement, you will be asked in the application procedure to upload one of the requested language certificates:

  • IELTS (academic) with an overall band score of at least 6.0 (with a minimum sub-score of 6.0 for speaking and writing) and certificates not older than two years. 
  • TOEFL iBT (internet-based) with an overall score of 80 (with a minimum sub-score of 20 for speaking) and certificates not older than two years. Please note that the University of Twente does not accept the MyBest scores of the TOEFL test.
  • Cambridge C1 Advanced Formerly known as; Cambridge English Advanced (CAE), obtained with an A, B or C grade.
  • Cambridge C2 Proficiency Formerly known as; Cambridge English Proficiency (CPE) obtained with an A, B or C grade.

Only these internationally recognised test results are accepted. Without a valid certificate, we cannot process your application.  

Other requirements

  • Ensure you have obtained a valid English test result before the application deadline. If your application is accompanied by a language test score report with a test date after our application deadline, we will not process it. Therefore, make sure to do the test in advance, as it will take time for you to get the official certificate.
  • When applying for a scholarship, the language requirements may be different because scholarship providers may have different requirements.
  • If you have studied in a former British or American colony, you must take one of the internationally recognised English language tests.

You are exempted from the English language requirement if you hold:

  • a relevant bachelor's degree from an accredited academic institution in the Netherlands
  • if you are a national of one of the countries in this list (PDF)
  • a three-year bachelor's degree in Australia, Canada (English-speaking part), Ireland, New Zealand, UK or USA. When your awarding institution is in one of these countries, but your teaching institution was not, you are not exempted. The same rule applies to distance (online) education.

Online English tests during COVID-19

We acknowledge the difficulties experienced worldwide in taking the compulsory language test, due to the Covid-19 situation. Alternative English tests can be:

Please note that other online English language tests (i.e. IELTS Indicator test, Cambridge online test, etc.) will not be accepted.

Computer skills

To follow online education you must have basic computer experience, regular access to internet, and e-mail. For some courses, additional computer skills are required (see description of specific course).

Technical requirements online education and assessment

For online education, we formulated guidelines to guarantee optimal performance. For online oral exams and proctoring during online assessments, the webcam and headset requirements need to be met.

GIS and remote sensing

Most online courses, except for the introductory course, require knowledge of, and skills in, working with GIS and/or digital image processing of remotely sensed data.

Candidates are asked to provide proof of identity during the registration process.

Hardware and software requirements

Since the computer is used for both the practical exercises and the communication via the internet you are expected to have a computer capable of running ILWIS (standard PC or laptop is OK) and an internet connection. The course is made for the Open Source GIS software ILWIS (Integrated Land and Water Information Systems. We will use email and skype for individual communication and a discussion board in Canvas  for group communication. There is also a Chat function in Canvas.

All course material can be downloaded from Canvas, our educational system. Besides ILWIS you will work with MS Excel and Word.

The study load is at least 20-24  hours per week. You have to make choices in tasks and offered links and background study materials in order not to make too many study hours. Try to construct your own simple anaglyph glasses for stereo viewing in one of the exercises.

What more there is to know?

This online course is based on a module of one of ITC's degree courses. Successful completion will lead to exemption for that course in the degree course.
