Mexico marks Jorullo’s 250th birthday 30 September 2009

Mexico has been marking the 250th anniversary of the appearance of Jorullo volcano, a cinder cone in the Michoacán-Guanajuato volcanic field situated in the southern state of Michoacán. The eruption which produced Jorullo began on 29 September 1759 and continued for 15 years, with lava flows, ashfall and mudflows affecting the surrounding landscape. By the end of the eruption the cone had reached a height of 1320 metres, with a 400-metre-wide crater 150 metres deep, and Jorullo’s lava flows had covered 9 square kilometres around the volcano.

A number of events will be taking place in Mexico to mark the anniversary, including a conference organized by the Universidad Nacional Autónoma de México. Scientist Víctor Huco Garduño Monroy of the Universidad Michoacana de San Nicolás de Hidalgo (UMSNH) has taken the opportunity of the anniversary to warn of the continuing dangers posed by volcanic activity in Michoacán:

Michoacán is located in an area of ‘high risk’ in terms of earthquakes and volcanic activity, as recorded in just over one thousand volcanic cones on the meseta purépecha, which has the potential to give rise to new volcanoes. However, there is as yet no state seismological network, nor any regional seismological or geological monitoring … There is a high rate of the emergence of new volcanoes that could in future give us a scenario like that of Paricutín or Jorullo.

The emergence of Paricutín in 1943 was the most recent eruptive activity in the
Michoacán volcanic field. Paricutín, like Jorullo, appeared from nowhere, gradually building into a cone 424 metres high and swallowing two villages and a large area of farmland before the eruption ceased in 1952. It is certain that the future will see similar eruptions in Michoacán – new Paricutíns, and new Jorullos.
