6. SOP of MMS No action is taken on earthquakes that is less than 5.9 in magnitude How ever, if there is an earthquake in the Andaman Islands or the Carlsberg region, SMS will be sent to the task force group. If there is an earthquake above 7.0 in another area of the world, it will be notified to the task force via SMS If there is an earthquake of 7.0 in the Indian Ocean, we fall in to the alert system.
