WHY? • Hundreds of millions live within 20 km of an active volcano. • Estimated 50 000 lives saved in last century by timely evacuations based on information from volcano monitoring (GAR15 report)

3 FRINGE Workshop Volcano Pilot Frascati, Italy 23-27 March, 2015

WHAT IS MISSING? • Relatively few volcanoes are permanently monitored by ground based instruments • Volcano observatories often do not use EO data • Current EO data collection is not coordinated for volcano monitoring • Need systematic observations before, during, and after volcanic events

4 FRINGE Workshop Objectives of the Pilot Frascati, Italy 23-27 March, 2015

Objective A – Regional Demonstration

Objective B – Supporting Geohazard Supersites and Natural Laboratories

Objective C – Significant Global Event

5 Pilot Region: Latin America FRINGE Workshop Frascati, Italy 23-27 March, 2015

Santorini Report aims:

1) global background observations at all Holocene volcanoes

2) weekly observations at restless volcanoes

3) daily observation at erupting volcanoes Pilot Region: Latin America FRINGE Workshop Frascati, Italy 23-27 March, 2015

Data for target volcanoes have generously been provided by ASI, CSA and DLR FRINGE Workshop Timeline Frascati, Italy 23-27 March, 2015

Objective A Timeline:

2014: -Begin studies of target volcanoes (first data arrived in August 2014)

2015: -Continue studies of target volcanoes -Begin quarterly monitoring of all Latin American volcanoes

2016: -Continues studies of target volcanoes and regional monitoring -Collect feedback from end users

2017: -Develop broader EO strategy based on lessons learned during pilot

RSAT-2 amplitude image 06/03/12 Topographic change at Reventador Feb 2000 – Sept 2011

• Reventador had its largest historical eruption in 2002 and the eruption is still ongoing • CEOS RADARSAT-2 and TanDEM-X data has shown the extent and thickness of new lava flows between 2011 and 2014 • Data provide insights into morphology and rheology of andesite lava flows Reventador, Ecuador FRINGE Workshop Frascati, Italy 23-27 March, 2015 Arnold, Bristol

Sabancaya volcano, Perú FRINGE Workshop Frascati, Italy 23-27 March, 2015

• Unrest started in Feb. 2013 • Complex sequence of mainly tectonic earthquakes • Culminated (so far) in small August 2014 eruptions. • Remote sensing (thermal & InSAR) sent to end users: paper accepted Cordon Caulle volcano, Chile FRINGE Workshop Frascati, Italy 23-27 March, 2015

• Large Plinian eruption in 2011- 2012

• CEOS RADARSAT-2 and COSMO-SkyMed SAR data has discovered widespread post- eruptive volcano inflation (~20 cm/yr) ongoing as of March 2015.

• No increase in seismicity above background.

• Met with OVDAS (Observatorio Delgado, Cornell Volcanológico de los del Sur, Chile) in Jan. 2015. Results are helping shape GPS monitoring strategy FRINGE Workshop Conclusions Frascati, Italy 23-27 March, 2015

• Initial results of the CEOS volcano pilot show previously unidentified deformation at target volcanoes in Latin America

• Currently expanding number of target volcanoes and will shortly begin comprehensive whole scale monitoring with Sentinel-1A and ALOS 2

• Continued communication with end users will help shape future EO strategy for disaster risk management

Thank you FRINGE Workshop Frascati, Italy 23-27 March, 2015

We are open to having new members in the pilot who are committed to the goals of the pilot, working with volcano observatories in Latin America

Independent of the pilot, we are always looking to work with others to monitor volcanoes in the region via collaborations.
