Macroseismic

Macroseismic intensities (EMS) calculated in 5 km grid squares from 17 felt reports. A minimum of five observations are needed to calculate an intensity. If there are less than five then the value is given as "felt". "not felt" means that reports explicitly stating that nothing was felt have been received.
