El Chichón, also known as Chichonal, is an active volcano in Francisco León, north-western Chiapas, Mexico. El Chichón is part of a geologic zone known as the Chiapanecan Volcanic Arc. El Chichón is a complex of domes with a tuff ring, made of ejected volcanic material, located between the Trans-Mexican Volcanic Belt and the Central America Volcanic Arc. El Chichón erupted in 1982; prior to this, activity had not occurred since c.1360, although debates in literature occur around an eruption occurring in c.1850.El Chichón became famous for its 1982 eruption. In little under a week, the presumed dormant volcano produced three plinian eruptions (March 29, April 3, and April 4). The eruptions generated a substantial amount of sulfur dioxide and particulates into the atmosphere. The total volume of the eruption was much smaller than the famous eruption of Pinatubo in 1991; however El Chichón's impacts were equally significant on global climate. El Chichón is often overlooked in comparison to other historic eruptions, yet the 1982 eruptions provide important lessons on preparation for volcanic disasters and the influence volcanoes can have on climate.

The 1988 Armenian earthquake, also known as the Spitak earthquake (Armenian: Սպիտակի երկրաշարժ, Spitaki yerkrasharj), occurred on December 7 at 11:41 local time with a surface wave magnitude of 6.8 and a maximum MSK intensity of X (Devastating). The shock occurred in the northern region of Armenia (then part of the Soviet Union) which is vulnerable to large and destructive earthquakes and is part of a larger active seismic belt that stretches from the Alps to the Himalayas. Activity in the area is associated with tectonic plate boundary interaction and the source of the event was slip on a thrust fault just to the north of Spitak. The complex incident ruptured multiple faults, with a strike-slip event occurring shortly after the initiation of the mainshock. Between 25,000 and 50,000 were killed and up to 130,000 were injured. Seismologists thoroughly studied the effects of the Spitak event, including the mainshock and aftershock fault rupture mechanisms, and were on site setting up temporary seismometers before the end of 1988. Earthquake engineering experts scrutinized building construction styles and found fault in the poorly constructed apartments and other buildings that were built during the Era of Stagnation under the rule of Leonid Brezhnev. The cities of Spitak, Leninakan (Gyumri) and Kirovakan (Vanadzor) were greatly affected with large losses of life and devastating effects to buildings and other structures. A number of the smaller outlying villages away from the larger population centers were also severely affected. Despite the tensions of the Cold War, Soviet leader Mikhail Gorbachev formally asked the United States for humanitarian help within a few days of the earthquake, the first such request since the late 1940s. One hundred and thirteen countries sent substantial amounts of humanitarian aid to the Soviet Union in the form of rescue equipment, search teams and medical supplies. Private donations and assistance from non-governmental organizations also had a large part of the international effort. While transporting some of these supplies to the region, a Soviet aircraft carrying 9 crew members and 69 military personnel, and a transport plane from Yugoslavia, were both destroyed in separate incidents. In support of the relief effort, recording artists united to produce several music-related contributions for the victims of the quake. A song was produced by a duo of French composers (including Charles Aznavour) and a studio album that featured songs donated by mainstream rock bands was released from the Rock Aid Armenia effort by the British music industry.
