up to 9 meters Tom Parsons 9 meters 240 km long 20 km deep northeastern and southwestern ends high risk
How large was the displacement? Who warned of possible seismic activity in the area beforehand? What did the United States Geological Survey show as the amount of displacement? How long was the fault where the quake occurred? How deep is the fault? Where on the fault is the possibility of future earthquakes increased? What did Tom Parsons consider as the risk factor for strong future quakes?
In a United States Geological Survey (USGS) study, preliminary rupture models of the earthquake indicated displacement of up to 9 meters along a fault approximately 240 km long by 20 km deep. The earthquake generated deformations of the surface greater than 3 meters and increased the stress (and probability of occurrence of future events) at the northeastern and southwestern ends of the fault. On May 20, USGS seismologist Tom Parsons warned that there is "high risk" of a major M>7 aftershock over the next weeks or months.
