Several SM and crowdsourcing platforms were mentioned during the interview and recommendations about how to safely contribute with useful data after an earthquake through these platforms were formulated by Dr Contreras. She also explained how natural language processing techniques (NLP) such as sentiment analysis (SA) and topic analysis are applied to extract meaningful information from the text data collected through SM and crowdsourcing platforms after disasters.

Dr Contreras mentioned the data collected and the ongoing analyses related to emergency response to the earthquakes in Albania (2019), Zagreb and Aegean region (2020) and the 10th anniversaries of the earthquakes in L'Aquila (Italy), Haiti, Chile, Tohoku (Japan) and Christchurch (New Zealand) and the 5th anniversary of the earthquake in Nepal.
