Current challenge: to include whole Mediterranean area within the European E-science strategy in earthquake Seismology

• Mediterranean area, one of the most complex tectonic systems in the world, requires a coordinated monitoring and research effort for understanding.• E-science can make the difference.• Small targeted European-Mediterranean research infrastructure projects will give a high pay-off and promote long-term cooperation.
