Earthquake, Sichuan, China

Saturday's earthquake in Sichuan province killed at least 189 people, injured more than 11,000 and left nearly two dozen missing, mostly in the rural communities around Ya'an city, along the same seismic fault where a devastating quake to the north killed more than 90,000 people in Sichuan and neighboring areas five years ago in one of China's worst natural disasters.

The Lushan and Baoxing counties hardest-hit on Saturday had escaped the worst of the damage in the 2008 quake, and residents there said they benefited little from the rebuilding efforts, with no reinforcements or new evacuation procedures introduced in their remote communities.

Luo said he wished more had been done to make his community's buildings quake-resistant. "Maybe the country's leaders really wanted to help us, but when it comes to the lower levels the officials don't carry it out," he said.

Relief teams flew in helicopters and dynamited through landslides Sunday to reach some of the most isolated communities, where rescuers in orange overalls led sniffer dogs through piles of brick, concrete and wood debris to search for survivors.

The GCP event was set for 24 hours, using the typical protocol for great natural disasters. The quake occurred at 08:02 local time, which is 00:02 UTC. Thus the 24 hour period begins just minutes before the quake. The result is Chisquare 86987.014 on 86400 df, for p = 0.079 and Z = 1.411.

It is important to keep in mind that we have only a tiny statistical effect, so that it is always hard to distinguish signal from noise. This means that every "success" might be largely driven by chance, and every "null" might include a real signal overwhelmed by noise. In the long run, a real effect can be identified only by patiently accumulating replications of similar analyses.
