At the end of last month, the New York Times published a map called Where to Live to Avoid a Natural Disaster, measuring the risk to 379 U.S. metro areas from hurricanes, earthquakes and tornadoes. Matt Rosenberg doesn’t like this map: “This map is irresponsible as it gives a false sense of security to those who live in extremely hazardous cities and overstates the hazard in tornado-prone regions. Perhaps the map is simply a reflection of recent disasters in the news. Regardless, no city west of the Rocky Mountains should be listed as low risk as the entire Western United States is seismically active. They definitely could have done better.”
This map compares historical seismic activity on a gridded equal-population cartogram: the colours show past earthquake activity; the map is distorted by population. “The resulting map,” says the press release, “gives each person living on earth the same amount of space while also preserving the geographical reference. The map does not only show the areas that are at highest risk, but also how this risk relates to global population distribution.” More at Views of the World.

With this map, Earth Observatory connects the two major earthquakes to hit Christchurch, New Zealand:
This map shows the earthquakes that occurred near Christchurch since September 3, 2010. On that day a magnitude 7.1 quake struck to the west of Christchurch. Black circles represent earthquakes from September 3, 2010, until February 21, 2011. Red circles show the locations of the magnitude 6.3 quake and aftershocks on February 22 and the morning of February 23. Larger circles represent stronger earthquakes. Yellow shows urban areas, including Christchurch.
