Two explo­sions occurred near the finish line of the 117th Boston Marathon on Monday after­noon, killing three people, leaving more than 140 injured, and cre­ating a fright­ening scene during one of the city’s most cher­ished tra­di­tions that con­cludes only about a mile away from Northeastern’s main campus on Hunt­ington Avenue.

This har­rowing inci­dent has shocked and sad­dened all of us. It’s vital that we join together to draw strength and com­fort from each other, and to sup­port our home com­mu­nity, during this unset­tling time,” Pres­i­dent Joseph E. Aoun wrote in a mes­sage to the North­eastern com­mu­nity Monday night.

North­eastern will hold a vigil Tuesday at 4 p.m. in the Curry Stu­dent Center Ballroom.

Fol­lowing the blasts, North­eastern public safety offi­cials increased the amount of per­sonnel on duty and coor­di­nated with Boston emer­gency respon­ders to assist the response effort. The Office of Stu­dent Affairs was in con­tact with stu­dent groups and mem­bers of the uni­ver­sity com­mu­nity known to be par­tic­i­pating in the marathon and related activ­i­ties. Among them were North­eastern phys­ical therapy fac­ulty and stu­dents in the Bouvé Col­lege of Health Sci­ences who were vol­un­teering in the first med­ical tent at the marathon finish line—which is part of an annual effort—when vic­tims of the explo­sions were brought in for imme­diate treat­ment. The uni­ver­sity also made arrange­ments to tem­porarily house any North­eastern stu­dent who may have been dis­placed from off-​​campus housing because of the incident.

Stu­dents in need of assis­tance may con­tact the WeCare pro­gram at wecare@​neu.​edu or 617–373-4384. North­eastern fac­ulty and staff may con­tact the Employee Assis­tance Pro­gram at 877–739-3989.

On Tuesday, the Center for Spir­i­tu­ality, Dia­logue, and Ser­vice will also make spir­i­tual advisers and center staff avail­able to stu­dents, fac­ulty, and staff at 203 Ell Hall on a walk-​​in basis, or by appoint­ment by calling 617–373-2728 or by sending an email to csds@​neu.​edu. The Sacred Space and Reflec­tion Room in 200–203 Ell Hall will be open for pri­vate prayers and reflec­tion. In addi­tion, Uni­ver­sity Health and Coun­seling Ser­vices will be open Tuesday from 8 a.m. to 8 p.m.

North­eastern pro­vided text mes­sage and email updates to the uni­ver­sity com­mu­nity imme­di­ately fol­lowing Monday’s events via NUAlerts, a ser­vice that allows uni­ver­sity offi­cials to reach all stu­dents and staff with time-​​sensitive infor­ma­tion during unfore­seen events or emer­gen­cies. Stu­dents, fac­ulty, and staff are urged to make sure their con­tact infor­ma­tion, including their emer­gency con­tact infor­ma­tion, is updated. This can be done through the myNEU portal by first finding “self-​​service” under the “Ser­vices and Links” tab and then finding the sec­tion on con­tact information.
