Question: Kenji Satake was part of the team that worked on the 1700 earthquake that had what magnitude?

<P0-S0> The 1969 Bohai earthquake occurred on July 18, 1969, at 13:24 local time. <P0-S1>  The epicenter was located in the Bohai Sea, off the coast of Shandong Province, China. <P0-S2>  The magnitude of this earthquake is M 7.4. <P0-S3>  Areas of maximal intensity were mainly distributed around the estuary of the Yellow River. <P0-S4>  Ground cracks and sand boils were reported. <P0-S5>  The earthquake could be felt in Liaoning, Hebei, Beijing, Tianjin, Shanxi, Shandong, and Jiangsu. <P0-S6>  10 people were reported dead. <P0-S7>  This earthquake caused ground surface subsidences of about 15.1 cm ~ 15.8 cm in the Yellow River Delta region. <P0-S8>  The mechanism of this earthquake was of dextral strike-slip faulting. <P0-S9>  Although it was located near the Tancheng-Lujiang fault zone (郯庐断裂带), some researchers think that this earthquake was dominated by the seaward extending part of the Huanghekou-Liaocheng seismotectonic zone (黄河口-聊城地震构造带). <SEP> <P1-S0>  The megathrust earthquake involved the Juan de Fuca Plate that underlies the Pacific Ocean, from mid-Vancouver Island in British Columbia, Canada, south along the Pacific Northwest coast as far as northern California. <P1-S1> The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26 with an estimated moment magnitude of 8.7–9.2. <P1-S2>  The length of the fault rupture was about 1000 km with an average slip of 20 m . <SEP> <P2-S0> Kenji Satake is a Japanese seismologist who has made significant contributions to subduction and tsunami research. <P2-S1>  Along with Brian Atwater and David Yamaguchi, Satake assembled disparate pieces of information regarding a Japanese tsunami that had no known origin. <P2-S2>  The three scientists worked together to pinpoint a date, time, and location for the 1700 Cascadia earthquake – 9 p.m on January 26, 1700 – on the Cascadia Subduction Zone off the Pacific Northwest coast of North America. <SEP> <P3-S0> This is a list of earthquakes in 1950. <P3-S1>  Only magnitude 6.0 or greater earthquakes appear on the list. <P3-S2>  Lower magnitude events are included if they have caused death, injury or damage. <P3-S3>  Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. <P3-S4>  All dates are listed according to UTC time. <P3-S5>  The main event which dominated the year in terms of magnitude and deaths was the earthquake which struck India in August. <P3-S6>  With a magnitude of 8.6, it was one of the largest earthquakes of all time, and affected the eastern part of the country. <P3-S7>  There were 1,530 deaths, which was around three quarters of the yearly total. <P3-S8>  A number of other deadly events struck Colombia, Venezuela and Peru. <P3-S9>  There were 21 magnitude 7.0+ quakes. <P3-S10>  Aside from India, Chile was hit by a magnitude 8.2 event in December that left one person dead. <P3-S11>  Aftershock sequences contributed to a large number of magnitude 6.0–6.9 events, especially in India and Vanuatu (which also saw four magnitude 7.0+ quakes). <P3-S12>  Monthly summaries are included for the first time due to a rise in events being recorded and will continue to be featured every year from now.
