   Heavy rainfall drenched north-central Italy, especially the
   Emilia-Romagna region, between April 30 and late May 2023. On May 19,
   ReliefWeb advised that at least 20 rivers had overflowed and at least
   300 landslides had occurred. According to the World Health Organization
   (WHO), as of May 22 the flooding has led to the death of at least 23
   people in Italy and forced thousands of residents to flee their homes.
   10,000 people had been evacuated and 200 roads had been reported
   closed.

   On May 21, the Italian authorities activated the EU Civil Protection
   Mechanism, requesting assistance for high-capacity pumping equipment.
   The European Union mobilized offers of equipment from Austria,
   Bulgaria, Germany, France, Poland, Romania, Slovenia, and Slovakia.

   Floodwaters have lingered across much of the inundated region,
   including in the town of Conselice, in the province of Ravenna. On May
   26, the mayor of that town ordered the evacuation of all homes in the
   sections that are still flooded due to health and hygiene concerns
   brought on by “stagnant water, the failure of the sewage system, the
   possible interruptions to drinking water supply, and the presence of
   uncollected waste”. A vaccination program to protect against tetanus is
   also underway, according to media reports.

   On May 26, 2023, the Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Terra satellite acquired a false-color image of
   north-central Italy showing severe flooding of the region. In this type
   of image, water appears deep blue, vegetation looks green, and open or
   sparsely vegetated land is tan. The town of Ravenna is marked by a
   group of tan-toned pixels south of the large rounded lagoon-and-wetland
   complex of Valli de Comacchio. It is obvious in this image that
   waterways are swollen and flooding overlies fields, especially north of
   Valli de Comacchio.

   By clicking on the dates, it is easy to compare the May 26 image with a
   second Terra MODIS false-color image acquired on May 5. It is obvious
   that flooding is more severe in the May 26 image, especially in the
   south. However, May 5 also shows flooding following extreme rains of
   May 2-3 which delivered more than 20 centimeters (8 inches) in a
   24-hour period in some locations.
