説明
<jats:p>At 0033 UT on 9 June 1994, a great deep earthquake occurred 635 km beneath the Amazonian rain forest of northern Bolivia. The deep rupture of this record‐setting magnitude 8.3 shock lasted about a minute [Harvard University Centroid Moment Tensor Catalogue]. The seismic strain release of this single event, as indicated by its seismic moment, was greater than the total strain release for all deep earthquakes in the Harvard CMT catalogue during the previous 17 years of its coverage of global seismicity. Incredibly, ground motion was felt as far north as Seattle, Washington and Toronto, Canada. Evidently, it occurred within the subducting Nazca plate that is descending beneath South America. This earthquake reminds us of the sometimes grand scale of deep seismic failure and of the need to consider more closely the physical processes that accompany slab descent and, in particular, how such earthquakes may reflect the inner workings of slabs.</jats:p>
