History of Volcanology Timeline

(79 CE – Present)

Volcanology is the scientific study of volcanoes, lava, magma, and related geological phenomena. The history of volcanology spans thousands of years, from ancient civilizations attributing eruptions to gods, to early natural philosophers like Pliny the Elder documenting eruptions, through the birth of modern scientific study in the 18th and 19th centuries with pioneers such as William Hamilton and Thomas Jaggar, to today's advanced monitoring technologies including seismology, satellite imagery, and gas analysis used to forecast eruptions and protect communities.

Ancient and Medieval Theories

Etna eruption kills over 15,000

1169

The catastrophic eruption of Mount Etna in 1169 claimed more than 15,000 lives among its inhabitants. Such devastating events shaped how medieval communities understood volcanoes, often through religious and animistic interpretations involving saints and divine forces.

Bernard Palissy investigates geological origins

1550

Bernard Palissy was among the Renaissance observers who pursued empirical questions about the nature and history of the Earth, contributing to a growing body of knowledge that challenged purely classical explanations of volcanoes and earthquakes.

Early Modern Volcanology

Many theories of volcanic action framed

1580 - 1660

During the late sixteenth and mid-seventeenth centuries, many theories of volcanic action were framed. Natural philosophers across Europe debated whether fire, water, or chemical reactions drove eruptions, setting the stage for systematic volcanological inquiry.

The great 1631 eruption of Mount Vesuvius

Dec 16, 1631

The 1631 eruption of Mount Vesuvius was the largest eruption of the volcano since 79 AD. Its devastation inspired an extraordinary outpouring of scholarship: no fewer than 44 books cover this single event, including Recupito's influential account.

Recupito documents the 1631 Vesuvius eruption

1632

Giulio Cesare Recupito published his account of the 1631 eruption of Mount Vesuvius in 1632 and later editions. His chronicle became a standard source of information about the volcano, which had produced its largest eruption since 79 AD.

Athanasius Kircher witnesses Etna and Stromboli eruptions

1637 - 1680

The Jesuit Athanasius Kircher (1602–1680) witnessed eruptions of Mount Etna and Stromboli, then visited the crater of Vesuvius. He published his view of an Earth with a central fire connected to numerous others caused by the burning of sulfur, bitumen and coal.

Wave of theories of the Earth published

1650 - 1750

The causes of volcanic and seismic phenomena were discussed in the large number of theories of the Earth that were published in the hundred years after 1650, a flourishing period of speculative but increasingly systematic geophysical thought.

Vesuvius rains pyroxene crystals on villages

1660

In 1660 the eruption of Vesuvius rained twinned pyroxene crystals and ash upon the nearby villages. This remarkable deposit drew scholarly attention and contributed to the growing literature documenting Vesuvian eruptions in detail.

Kircher publishes his central fire theory

1664

Building on his firsthand observations of Italian volcanoes, Kircher articulated a model of an Earth with a central fire linked to numerous subsidiary fires fueled by sulfur, bitumen and coal — one of the most influential early modern theories of volcanic action.

Saints invoked against the 1669 Etna eruption

1669

Despite advancing scientific understanding, popular religion persisted: the saint whose intercession had been sought historically was invoked again for the 1669 Etna eruption, and again for an outbreak endangering the town of Nicolosi in 1886.

Borelli's account of the 1669 Etna eruption

1670

Italian natural philosophers living near active volcanoes wrote long and learned books on the subject. Giovanni Alfonso Borelli's account of the eruption of Mount Etna in 1669 became a standard source of information for students of volcanism.

Animistic philosophy wanes in Europe

1690 - 1799

This animistic philosophy, which attributed volcanic phenomena to spirits and supernatural forces, was waning by the end of the seventeenth century, though traces continued well into the eighteenth century before fully giving way to naturalistic explanations.

Serao publishes account of the 1737 Vesuvius eruption

1737

Francesco Serao published his account of the eruption of Vesuvius in 1737, with editions in French and English. Together with Borelli's and Recupito's works, it formed a canon of authoritative descriptions of Italian volcanic eruptions.
