Over 1 million unique users posted more than 2.7 million tweets in just 3 days following the triple bomb blasts that struck Mumbai on July 13, 2011. Out of these, over 68,000 tweets were “original tweets” (in contrast to retweets) and related to the bombings. An analysis of these tweets yielded some interesting patterns. (Note that the Ushahidi Map of the bombings captured ~150 reports; more here).
One unique aspect of this study (PDF) is the methodology used to assess the quality of the Twitter dataset. The number of tweets per user was graphed in order to test for a power law distribution. The graph below shows the log distri-bution of the number of tweets per user. The straight lines suggests power law behavior. This finding is in line with previous research done on Twitter. So the authors conclude that the quality of the dataset is comparable to the quality of Twitter datasets used in other peer-reviewed studies.
My Internews colleagues have just released this important report on the role of communications in the 2011 Japan Earthquake. Independent reports like this one are absolutely key to building the much-needed evidence base of humanitarian technology. Internews should thus be applauded for investing in this important report. The purpose of my blog post is to highlight findings that I found most interesting and to fill some of the gaps in the report’s coverage.
I’ll start with the gaps since there are far fewer of these. While the report does reference the Sinsai Crisis Map, it over looks a number of key points that were quickly identified in an email reply just 61 minutes after Internews posted the study on the CrisisMappers list-serve. These points were made by my colleague Jeffrey Reynolds who spearheaded some of the digital response efforts from The Fletcher School in Boston:
“As one of the members who initiated crisis mapping effort in the aftermath of the Great East Japan Earthquake, I’d like to set the record straight on 4 points:
The crisis mapping effort started at the Fletcher School with students from Tufts, Harvard, MIT, and BU within a couple hours of the earthquake. We took initial feeds from the SAVE JAPAN! website and put them into the existing OpenStreetMap (OSM) for Japan. This point is not to take credit, but to underscore that small efforts, distant from a catastrophe, can generate momentum – especially when the infrastructure in area/country in question is compromised.
Anecdotally, crisis mappers in Boston who have since returned to Japan told me that at least 3 people were saved because of the map.
Although crisis mapping efforts may not have been well known by victims of the quake and tsunami, the embassy community in Tokyo leveraged the crisis map to identify their citizens in the Tohuku region. As the proliferation of crisis map-like platforms continues, e.g., Waze, victims in future crises will probably gravitate to social media faster than they did in Japan. Social media, specifically crisis mapping, has revolutionized the role of victim in disasters–from consumer of services, to consumer of relief AND supplier of information.
The crisis mapping community would be wise to work with Twitter and other suppliers of information to develop algorithms that minimise noise and duplication of information.
Thank you for telling this important story about the March 11 earthquake. May it lead to the reduction of suffering in current crises and those to come.” Someone else on CrisisMappers noted that “the first OSM mappers of satellite imagery from Japan were the mappers from Haiti who we trained after their own string of catastrophes.” Internews’s reply to this feedback was exemplary and far more constructive than the brouhaha that occurred over the Disaster 2.0 Report. So I applaud them for how positive, pro-active and engaging they have been to the constructive feedback.
I recently had the distinct pleasure of participating in a fascination workshop on “Information and Communication Technology in Areas of Limited Statehood: A New Form of Governance?” The workshop was organized by the Frei Universität’s program on Governance in Areas of Limited Statehood and co-directed by Professors Gregor Walter-Drop and Steven Livingston.

My colleague Gregory Asmolov made the link explicit during his excellent presentation on “Russian Wildfires and Alternative Modes of Governance: The Role of Crowdsourcing in Areas of Limited Statehood.” Here’s a summary:
“Because of it’s geographical size, high degree of corruption, and reliance on an extraction economy, governance by government in Russia is often weak and ineffective. Russian political expert Liliya Shevtzova goes so far as to claim that the current regime is an imitation of governance. The 2010 wildfires demonstrated the limited capacity of the state to provide effective emergency response. Information technologies, and crowdsourcing platforms in particular, fulfill the gap of the limited statehood. At the same time, however, the Russian government is also trying to use ICT to increase its claims to effective governance.”
Phi Beta Iota: This post is much more than a post. To the best of our (naturally limited) knowledge, this is the first and the best statement that clearly distinguished among “imitation governance,” spontaneous “self-governance,” and the role that information technology plays in making a mockery of the first and a reality of the second.
UN-SPIDER aims at providing universal access to all types of space-based information and services relevant to disaster management by being a gateway to space information for disaster management support; serving as a bridge to connect the disaster management and space communities; and being a facilitator of capacity-building and institutional strengthening.
