Caltech Emergency Notification System

Make sure you receive immediate notification by entering your contact information into the Emergency Notification System.

In the event of a fire, earthquake or other emergency, members of the Caltech community need information as quickly as possible: Has the campus been closed? Do we need to evacuate or take shelter? What's happening?

Caltech has contracted with Everbridge to provide emergency notification to all Caltech students, faculty and staff using the contact information from access.caltech. To be included in the notification process, at least one valid phone number is required for each person.

For this system to be effective, your access.caltech contact information must be current.To verify or update your contact information, please:

  1. Go to http://access.caltech.edu
  2. Log in with your access.caltech username and password
  3. Go to My Personal Information
  4. Click on Name and E-mail and enter/verify/correct your primary e-mail address
  5. Click on Addresses and Phones and review/edit/add phone numbers
