Description: 

Developments in transportable short-period seismic node technology presents many opportunities for targeted subsurface and earthquake studies. For example, low cost nodes have the potential to transform earthquake science in high risk countries that cannot afford the costs of maintaining a traditional seismic network. We have recently deployed nodal arrays following large earthquakes in Indonesia, to record valuable aftershock data revealing earthquake rupture patterns and fault geometry. Since the instruments are small and can be deployed in any configuration, they are uniquely able to be used in environments ranging from jungles to cities. A recent nodal survey across the city nation of Singapore has provided valuable constraints on the seismic hazard and subsurface structure. In this presentation I’ll discuss what we have done at the Earth Observatory of Singapore with a transportable array of 200 nodes.
