Dear all,

This week we have:

Esther Ruth Guðmundsdóttir (Faculty of Earth Sciences, University of 
Iceland)

Title: Explosive volcanic activity in Iceland during the Weichelian – 
Different from the Holocene?

Abstract: Eruption frequency is high in Iceland and has been estimated 
to exceed 20 eruptions per century on average during the Holocene. The 
majority of the eruptions are mafic (~90%) and predominantly explosive 
(~70%).For the past 10.000 years the explosive activity in Iceland is 
fairly well known based on numerous soil profiles and lake sediment 
archives across the country. What about during the Weichelian? How was 
the explosive volcanic activity in Iceland during this last glaciation? 
Was it similar to the Holocene? Which volcanoes were active and what was 
the level of their tephra producing activity? To answer these questions 
marine sediments extending 50.000 years er being investigated.

Date: Friday, 1st December
Time: 12:30
Place: 3rd Floor meeting room, Askja

All are welcome.

Best wishes
Maxwell
