Short summary

Every person is a seismometer. By using people’s reports submitted online to European seismological agencies, we made new grid cell shaking intensity maps of the 2011 Goch (DE) and 2015 Ramsgate (UK) M₄ earthquakes. Both events were widely felt in NW Europe and had non-concentric shaking intensity patterns which are strongly linked to the bedrock depth in the felt area. Storing intensity data in grid cells is a promising tool for seismological agencies to share intensity data anonymously.
