These two 19th century Latin American scientists provide the first direct observations that can be linked to the 'Unknown' eruption. More importantly, the accounts date the eruption to within a fortnight of 4 December Dr Erica Hendy said: "There have to be more observations hidden away, for example in ship logs. Having a date for the eruption will now make it much easier to track these down, and maybe even pinpoint the volcano. Climate modelling of this fascinating decade will also now be more accurate because the season of the eruption determines how the aerosols disperse around the globe and where climatic effects are felt.
Alvaro Guevara-Murua added: "This study has meant delving into many fields of research -- obviously paleoclimatology and volcanology, but also 19th century meteorology and Spanish colonial history -- and has also needed rigorous precision to correctly translate the words of two scientists writing years ago.

The "Babad"is a horrifying record of the last days of a kingdom. In the ancient manuscript, Lavigne came across a familiar name — Rinjani. It was followed by the Old Javanese word for avalanche. Whatever Samalas had been, its demise was catastrophic. In the aftermath of the "collapse," the anonymous historian describes "large flows of debris" and a "noise coming from boulders.
These same "avalanches" of superheated gas and rock were what wiped Pompeii off the map in A. It doesn't take fifteen volcanologists to figure out that the "Samalas" mentioned in the Babad Lombok was probably a volcano. The fact that it doesn't exist now, combined with Lombok's conspicuous crater, left a tantalizing possibility: Was Segara Anak caldera all that was left of Samalas? Archives showed that, in the decade prior to the fall of the Ptolemaic dynasty — which ended with Cleopatra 's death in 30 B.
Moreover, samples taken from ice cores provided data about volcanic eruptions that aligned with notable social unraveling, the study authors wrote. For example, a massive volcanic eruption in the Northern Hemisphere in 44 B. Because Egyptian agriculture depended almost entirely on summer flooding, interruptions in the floods could devastate crops, thus leading to famines and an increase in social tensions as people grew hungry and desperate.
The film's epilogue displays a graphic stating that the volcano, named "Mount Wilshire", is still in an active state.

Tuff cones are less common than cinder cones and generally form at magma-water boundaries. The eruption took place in very moist conditions, which allowed much water to permeate into the volcano, creating what is called a wet eruption. The area has a very rich volcanic history and the volcano is still considered active, despite not having an eruption for more than years.
