There is an instinct, when things go bad, to want to make sense of the situation by putting the fragments of information that you have on a map. Things are going badly around London tonight, and several people are making sense of it the best they can with maps of what is being reported on Twitter as #londonriot.
I'm keeping links to the original sites here, but the maps I'm including are not live embedded versions – click through for those – but rather snapshots of a moment in time.
The Telegraph: London Riots, all incidents mapped in London and around the UK. Pins on the map link to incident reports, many from the Telegraph live blog.
Channel 4's London Riots Interactive Timeline Map shows incidents as red targets on a dark background. The interactive slider (not shown) lets you watch how incidents have spread over time.
LondonRiotsMap.appspot.com uses the hash tag #londonriot combined with mentions of London postal codes to parcel out the information across a map. It's a quick way to distribute the information geographically, but it's not especially precise, as it will occasionally have someone commenting about a location that does not have any incidents going on. Ben Firshman (@bfirsh) notes the limitations: "My map's not intended to replace editorially curated maps. It's a visualisation."
