NEWS:
Our work following the Yogyakarta earthquake and Mount Merapi Volcano eruption suggests that the earthquake damage was amplified in regions subject to recent lahar dipositions, published in G-cubed.
Please check out a manuscript about the relationship of megathrust earthquakes and volcanic activity in Chile, Kamchatka, Aleutens and Indonesia, published in Geology.

Our work at Mauna Loa on Hawaii suggests that volcanic activity is directed or even controlled by the prestressing conditions. We simulated the development of the stress field of the past 25 years, and find that magma emplacement occurs just in these parts of stress accumulation. Published in Science..
