In Costa Rica, Turrialba present since 14 am yesterday (15/07/2016) an increase of the scale of the tremor. Passive ash emissions are observed since 2 am, interspersed with some pause intervals.

They intensified around 11:30, and persist at 12:55 local , time of the report by the RSN. The ash column does not rise more than 300 meters of the crater and is quickly spreading to the southwest.

Earthquakes associated with fluid movements (LP) increased in the first half of July to Ticsani volcano, located in the department of Moquegua in Peru, of number of 33. An increase in the tremor, for more than six hours is reported the 13 July.

During the same period, the IGP has recorded 354 earthquakes related to rockls fracturing, located in three groups, the first near the Ticsani, the second located at 7 km east of the massif and a third at 13 km to the South-East. The sulfur dioxide values ​​remain low and no thermal anomaly was detected.

At Piton de la Fournaise, the OVPF signals a rise in inflation since July 13.

The report of 14 July described 26 superficial VT earthquakes in the summit craters, mostly between 8 and 14.07.2016, and some 111 collapses located in the Dolomieu crater, at the Enclos Fouque and on the flows from August to October 2015. SO2 emissions at the summit remain under the detection threshold.

To be continued!
