Abstract. One of the largest climate forcing eruptions of the nineteenth century was, until recently, believed to have taken place at Babuyan Claro volcano, in the Philippines, in 1831. However, a recent investigation found no reliable evidence of such an eruption, suggesting that the 1831 eruption must have taken place elsewhere. A newly compiled dataset of reported observations of a blue, purple and green sun in August 1831 is here used to reconstruct the transport of a stratospheric aerosol…

Out of the blue: Volcanic SO2 emissions during the 2021–2022 eruptions of Hunga Tonga—Hunga Ha’apai (Tonga)

Most volcanism on Earth is submarine, but volcanic gas emissions by submarine eruptions are rarely observed and hence largely unquantified. On 15 January 2022 a submarine eruption of Hunga



The 1831 eruption of Babuyan Claro that never happened: has the source of one of the largest volcanic climate forcing events of the nineteenth century been misattributed?

The 1831 eruption of Babuyan Claro in the Philippines is regarded as one of the most significant volcanic climate forcing events of the nineteenth century. Modern databases have assigned the eruption

Last phase of the Little Ice Age forced by volcanic eruptions

During the first half of the nineteenth century, several large tropical volcanic eruptions occurred within less than three decades. The global climate effects of the 1815 Tambora eruption have been

The Atmospheric Impact of the 1991 Mount Pinatubo Eruption

The 1991 eruption of Pinatubo produced about 5 cubic kilometers of dacitic magma and may be the second largest volcanic eruption of the century. Eruption columns reached 40 kilometers in altitude and

A reappraisal of the 1835 eruption of Cosigüina and its atmospheric impact

In the “great” January 1835 eruption of Cosigüina volcano, Nicaragua, andesitic magma and lithic material were erupted over a period of at least three days. Proximal facies consist of clastogenic

The last communication I had the honour to make to the Royal Society on this subject was dated the 25th October. Since that time the crater of the volcano, from the operation of various causes, has

Exploring the ‘prehistory’ of the equatorial stratosphere with observations following major volcanic eruptions

Since 1953 meteorological balloon soundings from low‐latitude stations have revealed that the prevailing winds in the equatorial stratosphere undergo a remarkable alternation between strong

Impact of the clouds of volcanic aerosols in Italy during the last 7 centuries

Intense natural pollution has occurred in the past in Italy corresponding to intense volcanic activity, which appears to have diminished somewhat in recent times. Between 1500 and 1900, Etna,

Sulphur-rich volcanic eruptions and stratospheric aerosols

During the past decade it has become clear that the long-lived stratospheric clouds produced by volcanic eruptions are composed largely of sulphuric acid aerosols1,2. The amount of sulphur-rich

Exploring the submarine Graham Bank in the Sicily Channel

In the Sicily Channel, volcanic activity has been concentrated mainly on the Pantelleria and Linosa islands, while minor submarine volcanism took place in the Adventure, Graham and Nameless banks.
