In a previous post, we wrote about how ICTs were helping people all around the world respond to the Nepal earthquake. Today, Luther Jeke takes a closer look at the mapping efforts during the response.

Do you remember where you were the morning of April 25, 2015? I will never forget. I was at my home in Washington D.C. catching up on emails and the news. I was shattered when I saw the headlines for the earthquake in Nepal. The 7.8 magnitude earthquake that was going to later claim more than 8,800 lives and injured more than 23,000.

I’m based in Washington D.C. through the Atlas Corps fellowship and have Nepali friends in the fellowship here as well. After getting the details of the devastation in Nepal from several news sources, I reached out to the other Nepali fellows, including Samita Thapa, who is based at TechChange. I knew that Nepalis who were living abroad may feel helpless being so far away and I had the thought: what if they could volunteer digitally?

Nepali volunteers

I have been a member of the Standby Task Force (SBTF) since 2011. The SBTF organizes digital volunteers into a flexible, trained and prepared network ready to deploy in crises. Launched at the 2010 International Conference on Crisis Mapping (ICCM 2010), the SBTF was created “to streamline online volunteer support for crisis mapping, following the lessons learned in Haiti, Chile and Pakistan, and to provide a dedicated interface for the humanitarian community.”

But just having a digital mapping community isn’t enough. Having local information and networks on the ground is crucial, so the three of us coordinated a group of Nepali volunteers to assist the SBTF digital humanitarian efforts that mapped the Nepal earthquake by analyzing social media content. Together, we were able to recruit around 200 Nepali volunteers who tirelessly helped the mapping team by feeding, translating, and verifying information from our social media network in and out of Nepal. We were constantly on Facebook, Twitter, and Skype over a period of two weeks to help with this digital humanitarian deployment and to map the crisis.

The Mappers

We helped the SBTF collect, verify and map over 1,000 lines in the information management database of the Nepal earthquake. About 5 million tweets were processed by the Artificial Intelligence in Disaster Relief platform (AIDR). Our volunteer group was instrumental in helping the SBTF click through more than 60,000 images and 10,000 messages that were being geolocated onto this map below, with around 200 volunteers joining the Nepal Advisors deployment.

The data was used by many humanitarian organisations like Doctors Without Borders, Nepal Youth Foundation, Government of Nepal, governments of various other countries responding to the earthquake, and more. It has been used to assist and accelerate the coordination of humanitarian groups on the ground. We processed an extraordinary range of data streams during the 12 days of the deployment and geolocated pictures and messages of needs and offers of assistance, provided maps and tables and supported other organisations and groups to streamline their processes. Our team worked closely with many other groups throughout this deployment. You can read about our efforts and success over on the SBTF blog.

I have learned from my mentor, Patrick Meier that anyone can be a digital humanitarian. All you need is a big heart and access to the Internet. I reached out to the Standby Task Force and with huge efforts from Medha and Samita, we founded a volunteer group of Nepalis to digitally support the work of the SBTF in Nepal. To learn more or to get involved, check out their website here. They can alway use your support whenever disaster strikes.

Digital mapping has been used in disaster response, maternal health, WASH programs, and more. Interested in learning more ways mapping is being used for social good? Sign up for our upcoming Mapping for Social Good online course now!

Did you see Facebook’s Safety Check feature recently? Did you use it?

Following the recent earthquake in Nepal, Facebook activated “Safety Check“, a feature that helps friends and relatives quickly find out whether their loved ones are safe. Safety Check was originally launched in October 2014 and was mainly based on experiences gained during the 2011 earthquake and Tsunami in Japan.

The idea is very simple: In case of a large scale emergency, Facebook can use the information it is constantly collecting about its users to determine who is likely to be in the affected area. It then asks these users to confirm whether they are safe and shares that information with their facebook friends. Alternatively, people can also report their facebook friends as being safe and those marked safe can see who marked them. People can also say “I’m not in the area”.

Safety Check is a dormant Facebook feature that is only activated when necessary. One thing that I had been curious about since the launch was how well Facebook would be able to determine whether someone was in the affected area.

According to the original press release:
“We’ll determine your location by looking at the city you have listed in your profile, your last location if you’ve opted in to the Nearby Friends product, and the city where you are using the internet.”

Indeed I quickly heard from two former colleagues who were in Nepal: One of them lives permanently in Kathmandu but was actually on a plane when the earthquake happened. In his case, Facebook assumed he was still in Nepal, because his phone was off at the time of the quake. In the absence of current information, Facebook took his home city and/or his last location, which was at the airport, to include him in the group of affected people.
The other person I know normally lives in the UK but was in Nepal on a trip. In his case, Facebook used the IP address of his last login to estimate his location.


Users see how many of their Facebook friends are
in the affected area and how many are safe.

Why this is relevant
Anyone who has ever been in a situation where family members or close friends are in danger, knows that finding out what happened to them is one of the first things on your mind. Not knowing is not only a source of great anxiety, but it can actually be dangerous if you yourself are also close to the affected area:

Think of a father who knows that his daughter was at a shopping mall downtown when the earthquake struck. If he doesn’t know what happened to his child, he will probably run to the shopping mall to find out. By doing so he can put himself at risk and he will not be at home to look after the other children when a strong aftershock occurs. He will also try to call his daughter every 5 seconds, thereby accidentally helping to crash the phone network.

On the other hand, we have now seen in a number of disasters that internet connections frequently remain functional (if slow) even when phone and SMS networks are down – to a large part because many people open their WiFi networks to let others use the internet.
Using social media is also much more efficient since one “I am safe” update will reach all of one’s friends, making multiple calls unnecessary, thus reducing further load on the telecommunications infrastructure.

The application also shows clearly whether people have
reported themselves as safe or whether others have done so for them. 

Why this is better
Of course, there are also other systems to find out whether friends and family are safe. Google, for example, has its “Person Finder“. The Red Cross Red Crescent Movement has been providing tracing and restoring family links services for many years and local government authorities, as well as embassies, are also very much involved in these tasks.

However all of them require that a (distressed) user finds out about these services and actively registers or gets in touch with them. That is a lot to ask of someone who just survived a disaster. Facebook’s Safety Check on the other hand is part of the normal Facebook application that most people are already familiar with. This reduces the barrier to share and receive information significantly which in turn reduces the load on the other, more sophisticated, systems like the Red Cross’ tracing program. Facebook’s Safety Check can provide clarity in many of the easy cases, freeing up resources for the difficult ones.

The current picture of Haiti is complex: millions of people are still displaced, billions of dollars in promised aid have yet to arrive, and there is still an extreme lack of infrastructure. However, there are thousands of NGOs working around the country, and some of the most promising work is being done in communications and connectivity. (more…)
