After the first responders have stabilized a situation, victims of natural disasters still have months, even years, of recovery ahead. For example, parts of Texas are still recovering from Hurricane Harvey (from August 2017), and many islands, such as Puerto Rico, were devastated by Hurricane Maria (September 2017).
Would you like to help? There are opportunities for Disaster Relief Training provided by the Missouri Baptist Convention. Many other denominations and organizations also organize training and trips.
In addition, AmeriCorps supports service around the nation. (Hopefully their web site will be active again soon!)
