Joint USGS - GEM Group on Global Probabilistic Modeling of Earthquake Recurrence Rates and Maximum Magnitudes Despite the best monitoring networks, the highest rate of earthquakes and the longest continuous recorded history in the world, this year’s M=9.0 Tohoku, Japan, earthquake was completely unforeseen. The Japanese had expected no larger than a M=8 quake in the Japan trench, 1/30 th the size of the Tohoku temblor. This year also saw the devastating M=6.3 Christchurch, New Zealand earthquake and the M=5.8 Virginia quake, and it marks the bicentennial of the enigmatic but destructive 1811 - 1812 M~7 ½ New Madrid, Missouri, earthquakes, each event an example of how poorly we can forecast earthquake rates or their ultimate size in the planet’s vast intraplate regions far from plate boundaries. The goal of the Global... Categories: Project; Tags: All Working Groups, Completed, Earthquakes, Natural Hazards, Seismicity
