UPDATE Sept. 20, 12:17 p.m. PT: More organizations have been added that are accepting donations for earthquake relief.

A devastating 7.1-magnitude earthquake struck near Mexico City on Tuesday, killing at least 139 people.

With power and phone lines down, people are having trouble getting in touch with loved ones. To make matters more stressful, the country was already recovering from an earthquake that hit less than two weeks ago.

Instead of feeling hopeless in the face of the destruction, here's how you can help earthquake victims.

Donate what you can

Organizations like UNICEF Mexico are looking for monetary donations.

There's a big need for clothes, water, and food. Giving to places like the Red Cross Mexico, Oxfam Mexico, Save the Children Mexico, and Direct Relief is a way to get resources flowing. Smaller nonprofits like Project Paz are also collecting donations for earthquake relief.

A rescue brigade, Topos Mexico, was huge part of efforts back in 1985 and is hard at work with the latest earthquakes and taking donations.

Local help

Locally, help is needed with volunteers getting dispatched to needed areas. Twitter is full of pleas for rescue teams. Although it's not much, a retweet could help spread the word about a community's needs.

Another community effort to help with limited communication is to open up Wi-Fi networks.

Mexico City officials are coordinating volunteers who want to help with rescue efforts. There's also a list of hostels throughout the city.

Social media for good

Social media is also helping people locate loved ones and reconnect families. Google has activated its people finder platform where people can share information about someone or ask for help locating a friend or family member.

A list of rescued people is growing on a public Google Spreadsheet.

Spreading other information could be helpful, like where to find free hospital visits and available apartments. People are also sharing public safety messages, like reminding others to keep streets as car-free as possible for rescue vehicles.

As the aftermath of the quake unfolds, more information on Mexico's needs and what can help the most will become more apparent. The need for help won't disappear anytime soon; this is an ongoing recovery.

UPDATE Sept. 20, 4:30 p.m. PT: GoFundMe is keeping track of crowdfunding campaigns for Mexico earthquake relief in one place. Some of the many campaigns include students from the University of Pennsylvania well on their way to raising $30,000 for the Mexican Red Cross. A Mexican-American group based in Massachusetts already surpassed its $10,000 goal to send money to the Topos rescue group.

Another campaign is from actress Salma Hayek, who contributed $100,000 for her native country. The money — so far more than $170,000 has been donated — is going to UNICEF and the organization's rescue teams in Mexico.
