Two days after a powerful tornado struck the city of Moore, Oklahoma, the situation on the ground is still dire. According to The Associated Press, the event killed at least 24 people and leveled scores of homes and businesses.

Part of the promise of technology is that it can help protect us from such events through prevention and appropriate response. The San Francisco-based tech company Recovers is working on just that. The firm has sent a group of employees to Moore, where they'll apply skills and experience gathered from other disasters to help in a range of ways, from building donation websites to organizing volunteers online.

Recovers CEO Caitria O'Neill joins Marketplace Tech host Ben Johnson to describe the tech challenges of natural disasters and recovery.
