Much of Madagascar has received above average rainfall since December. Photos taken from the International Space Station show how devastating floodwaters have spread in Madagascar, killing at least 31 people.

The images were posted on Twitter Tuesday by astronaut Christina Koch, who has spent 11 months in orbit and set a record for the longest spaceflight by a woman.

"Our thoughts are with those affected," Koch tweeted. "Stay safe."

Koch is due to return home from the space station next week.

At least 31 people have died and more than 16,000 have been displaced by the flooding, according to the U.N. Office for the Coordination of Human Affairs. The death toll could rise as many people still remain missing, the agency said.

More than 10,000 houses are flooded and 146 destroyed, and other key infrastructure such as roads, schools and a dam have sustained heavy damage. There are also fears of a food shortage due to flooded rice fields.

In all, some 107,000 people have been affected in at least seven regions of the country, which is an island in the Indian Ocean east of Mozambique.

The government has declared a state of emergency.

Much of Madagascar has received above average rainfall since December. Up to 14 inches has fallen over the past 10 days in some areas.

The period of heavy rainfall and flooding is in part due to a series of tropical disturbances that recently rolled eastward across.

Madagascar has a population of about 25 million people, according to the World Bank, and is considered one of the countries most impacted by climate change. The country experiences an average of three cyclones per year. Most recently, Tropical Cyclone Belna made landfall there in December.
