这篇报道综合了最近三年来的地震学进展。在这期问,有两种不同类型的地震发生,它们具有特殊的意义。第一种类型包括俯冲板块边界上的地震空区内发生的大地震。1985年3月3日智利瓦尔帕莱索地震(Ms=7.8,Mw=8.0),发生在一个具有较好证实的86±10年大地震周期的地区。这个地区的前一次大地震是在1906年。 1985年9月19日的墨西哥地震(Ms=8.1),发生在历史上没遭受大地震的米却肯空区。对板内带是真的空区或是无震滑移带还不知道。两次地震都是破坏性的。5,600多人死于墨
This report synthesizes the seismological advances of the past three years. During this period, there are two different types of earthquakes that have special significance. The first type includes large earthquakes that occur within the seismic zone on the subducting plate boundary. The March Valparaiso earthquake (Ms = 7.8, Mw = 8.0) on March 3, 1985 occurred in a well-established area of 86 ± 10 years of major earthquake. The last major earthquake in the area was in 1906. The Mexican earthquake of September 19, 1985 (Ms = 8.1) took place in the Michoacan area that has not suffered a major earthquake in history. On the board is really empty zone or no earthquake with the slip band does not know. Both earthquakes are destructive. 5,600 people died in ink
