GVP Weekly Volcanic Activity Report for September 29-October 5, 2010

New reports of volcanic activity from around the world! Thanks again to Sally Kuhn Sennert for putting together these reports for the Global Volcanism Program.


Some highlights:

Colombia It was a busy week, volcanically-speaking, in the South American nation. We're talked about Nevado del Ruiz and the GVP mentions that the volcano has also shown changes in "deformation and geochemistry", which for the latter I assume means from the gases being released (but it could be water as well). Over at Nevado del Huila, the active summit dome produced plumes that reached up to 7.5 km / 25,000 feet along with incandescence and hot rock falls as part of a partial dome collapse (spanish).

Chile Planchon-Peteroa continues to produce ash plumes that reach as high as 3-6 km / 10-20,000 feet. Changing winds have raised considered of ash fall (spanish) in communities near the volcano, but ONEMI says there is no real danger (spanish). The volcano remains on Yellow Status - you can check out the latest SERNAGEOMIN report here (spanish - follow Region del Maule - Reportes - 2010)

Guatemala Fuego continues to experience explosions - and even an occasional lahar. This continues the pattern from earlier this summer. Pacaya also produced weak steam plumes as part of its continuing activity.

Kuril Islands It has been a while since we talked about Sarychev Peak - a big newsmaker in 2009 - but the volcano does continue to be active. Ash plumes were detected from the island volcano by satellite. Currently, remote sensing by satellite is the only monitoring for the remote volcano, which lacks any seismic monitoring.

A world map of Virgin Mary apparitions

She met mere mortals with and without the Vatican's approval.

Strange Maps
  • For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
  • These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
  • Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.

Love in a time of migrants: on rethinking arranged marriages

Arranged marriages and Western romantic practices have more in common than we might think.

Culture & Religion

In his book In Praise of Love (2009), the French communist philosopher Alain Badiou attacks the notion of 'risk-free love', which he sees written in the commercial language of dating services that promise their customers 'love, without falling in love'.
