年3月18日，夏威夷基拉韦厄(Kilauea)火山喷发，火山灰从出口向外喷散。火山喷发产生岩屑散布于方圆30公顷，一处深受游客喜爱观景台也受到岩屑影响。这是海拔1277米基拉韦厄火山主火山口自从1924年以来首次喷发。58/75

年6月17日智利南部柴滕火山暴发。火山喷发出浓重烟尘，并伴有隆隆地动声，同时出现了两个新火山口。这座火山从5月2日开始喷发，已迫使4500名居民从柴滕火山附近一座小村庄撤出。从布兰科(Blanco)河中溢出水已经对这个村子造成严重破坏，因为有大量火山灰落入河中，河水变得非常粘稠。59/75年6月6日，位于印度尼西亚米纳哈萨半岛上索普坦火山喷出滚滚浓烟。索普坦火山当日开始喷发浓烟和火山灰，高度达2到4公里。
