“At times, the path is well-marked, but it crosses and intersects with many more that lead nowhere…” 2007 (© Jorge Alonso, via viajeros4x4.com). Approaching Volcán Lastarria from the NW.
GVP said in 2007: “The rarely visited Lastarria has not erupted in historical time, but has displayed strong fumarolic activity for at least 67 years. This is the first Bulletin report ever issued on this volcano; it presents new images of the steaming edifice…”
Not that the volcano wasn’t known as such – persistent fumarolic activity has been reported from the northwestern flanks since the earliest records were made. However, even the most recent eruptions appear to have predated the Spanish colonists: no records of large or small eruptions have ever been found. Yet, in 1900, Dr. L. Darapsky said “Lastarria volcano… is the only one in the district which shows signs of volcanic activity, Continue Reading

Here are some impressions, thoughts and photos from our visit. Continue Reading
Smith volcano, Babuyan Claro Island (© Garrison et al., 2018)
“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, particularly so when treated as a double eruption with the 1835 (VEI 5) eruption of Cosegüina, producing ‘enhanced’ forcing effects over a decadal time frame.”
Follows the course of much detective work and its conclusion:
“We therefore suggest that the 1831 eruption of Babuyan Claro is a false event and that one or more alternative eruptions will have to be identified as the source of the 1831 stratospheric sulphate aerosol.” Continue Reading
