Eruption of Wolf and Sinabung

On Isabela Island in the Galapagos archipelago, the eruption of Wolf volcano continues.

In recent days, the site Mirova reports an high thermal anomaly, and Aqua MODIS satellite imagery of June 18 show that the eruption site is now located in the caldera, a few kilometers west of the original site.

No news of the eruption on the site of the Parque Nacional, except a retweet from Andes EN, signaling that the population of  endemic pink iguanas remains stable despite the eruption.
