Query: Local information sources received the most attention from Puerto Ricans
  during the aftermath of Hurricane Mar\'ia   In September 2017, Hurricane Mar\'ia made landfall across the Caribbean
region as a category 4 storm. In the aftermath, many residents of Puerto Rico
were without power or clean running water for nearly a year. Using both English
and Spanish tweets from September 16 to October 15 2017, we investigate
discussion of Mar\'ia both on and off the island, constructing a proxy for the
temporal network of communication between victims of the hurricane and others.
We use information theoretic tools to compare the lexical divergence of
different subgroups within the network. Lastly, we quantify temporal changes in
user prominence throughout the event. We find at the global level that Spanish
tweets more often contained messages of hope and a focus on those helping. At
the local level, we find that information propagating among Puerto Ricans most
often originated from sources local to the island, such as journalists and
politicians. Critically, content from these accounts overshadows content from
celebrities, global news networks, and the like for the large majority of the
time period studied. Our findings reveal insight into ways social media
campaigns could be deployed to disseminate relief information during similar
events in the future.
