2010年1月12日的海地大地震给这个国家带来了巨大的破坏(图1)。在本周的Eos会刊中,3位著名地震学家以新闻圆桌的形式回答了Eos高级撰稿人Randy Showstack的问题。PaulMann,德克萨斯大学奥斯汀分校地球物理研究所高级研究员,刚刚结束了他和一名同事在海地对断层破裂的考察工作回到美国;他们正在计划不久的将来进行一次近海断层勘察。Glen Mattioli,阿肯色大学费耶特维尔(Fayetteville)分校地球科学教授,曾参加过在海地开展的GPS勘测工作。该小组致力于测量海地地震后的陆地形变,并架设了一组连续的GPS站点来调查震后滑移、黏弹性弛豫和震间形变回复时间(图2)。Mann、Mattioli及其同事的研究工作是由美国国家科学基金会的快速反应研究(RAPID)议案提供给普渡大学的拨款资助的,EricCalais是这个项目的首席研究员。Carol Prentice,美国地质调查局(USGS)地震灾害项目工作组的地震学家,自1991年起致力于加勒比海地区活断层的古地震学研究,包括对伊斯帕尼奥拉岛、波多黎各、特立尼达岛和牙买加等地区开展的研究项目。更多背景信息,请参阅刊登在Eos(91(4),30-31,26 January2010)上的一篇文章,题为:“海地地震彰显更好地利用地震信息的必要性”(见《国际地震动态》2010年第3期译文—编者注)。另外,美国地球物理联合会(AGU)设立了一个博客来支持对最近发生的地震的科学方面和政策方面话题的讨论(http://www.agu.org/blog/Haiti/)。反映海地地震中部分科学家的工作的另一个博客,请登录http:∥haitigps.wordpress.com/。 The earthquake in Haiti on January 12, 2010, caused tremendous damage to the country (Figure 1). In this week’s EOS journal, three prominent seismologists answered the question of Randy Showstack, a top Eos copywriter, in the form of a news roundtable. Paul Mann, a senior fellow at the Institute of Geophysics at the University of Texas at Austin, has just concluded the investigation of fault rupture in Haiti by a colleague and his colleagues back to the United States; they are planning an offshore survey in the near future. Glen Mattioli, Professor of Earth Sciences at the University of Arkansas at Fayetteville, has been involved in GPS surveys in Haiti. The group is dedicated to measuring land deformation after the earthquake in Haiti and has set up a series of successive GPS stations to investigate post-earthquake slippage, viscoelastic relaxation, and seismic deformation response time (Figure 2). Research by Mann, Mattioli and colleagues was funded by funding from Purdue University’s Rapid Response Research (RAPID) motion by the National Science Foundation, and Eric Calais is the lead researcher for the project. Carol Prentice, a seismologist at the USGS Earthquake Disaster Task Force, has been involved in paleoseismic studies of active faults in the Caribbean since 1991, including on the islands of Hispaniola, Puerto Rico, Research projects in the regions of Trinidad and Jamaica.

In addition, the American Geophysical Union (AGU) has set up a blog to support discussions on the scientific and policy aspects of the recent earthquake (http://www.agu.org/blog/Haiti/).
