Recovering batteries

07/05/2016

It was time to get the batteries which used to power the Doppler radar station before it was destroyed by the July 2015 eruption, during which a large PDC swept down the Montegrande ravine. Further activities were investigating some rather interesting surge deposits, block collisions in the PDC deposit, and starting a photogrammetric survey of the 2015 lava flow. The rainy season on the horizon will destroy the "tracks" bulldozed in the fresh deposits, making access more difficult.



BBC film unit

The producer and cameraman of the Central Mexico episode of a future documentary about the country were in Colima over the last 2 days to film the volcano. CIIV helped them obtain images from Volcancito of the volcano. Unfortunately there were less explosions whilst they were here, though a drone was used to get fantastic images of the growing and exploding lava dome.



New dome observed

16/02/2016

A slowly growing dome was observed during a recent CIIV flight over the volcano. It has a diameter of only 25 m at the moment and is clearly being disrupted by increasing explosivity. It was not a surprise since nightly incandescence seen over the crater could have only meant one thing. The event marks a break in over 5 months with purely explosive activity. High temperatures (almost 700 degrees) were measured at this stage mainly due to the small dimensions and high proportion of fresh material.



Visitors from Florida

14/02/2016

This week sees the visit of Sylvain Charbonnier and Zachary Atlas from the University of South Florida. We are continuing collaboration with a study of the July 2015 erupcion PDC deposits and changes on the petrology of recent eruption projects. We hope this will help pave the way for future exchange visit between students at the two universities. Sylvain is shown here with his student Elodie who is working on the study of the PDC deposits.



Continued explosions at Volcán de Colima

16/01/2016

2016 has the volcano continuing to produce several explosions a day such as the one in the photo at dusk on the 19th Jan. Some still show high temperatures with quite a large content of fine ash. A flight that was conducted on the 15th Jan. resulted in thermal images that showed a warm zone in the base of the crater but still no signs of a new effusive episode.
