Developments in transportable short-period seismic node technology, driven by industry, presents many opportunities for targeted subsurface and earthquake studies in academia. 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 the rupture patterns and fault geometry. Since the instruments are small, nimble 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 island city of Singapore provides geophysical insights into seismic hazard and subsurface structure. In this presentation I’ll discuss our experience and future plans for a transportable array of nodes.
