A strong aftershock has shaken Venezuela’s earthquake-devastated capital city, Caracas, sending residents screaming onto the streets in terror.

The massive jolt on Monday morning (local time) measured 4.6 on the Richter scale, according to the United States Geological Survey.

There were no immediate reports of additional damage from the aftershock, which also convulsed the hard-hit port city of La Guaira.

“Here we are again, back in the street. I don’t know when we’ll have a moment of true peace,” said Concepcion Hernandez, 51, who evacuated her apartment building in the Chacao municipality of Caracas.

The aftershock struck as civilians and emergency responders were combing through the ruins of fallen buildings for survivors.

Among the seeming miracles was the rescue of Aaron Levi, 21, who was pulled out after 106 hours trapped under the rubble in La Guaira, in a rescue operation that lasted 43 hours.

Homes and buildings have been so badly damaged from last week’s original twin quakes that President Delcy Rodriguez said people would have to be housed in camps.

Rodriguez said 15 shelters had been set up in La Guaira as well as 50 provisional camps to help people affected by the quakes.

The death toll continued to rise to 1719, according to Jorge Rodriguez, the acting president’s brother and president of the National Assembly.

There were 5034 injured and 15,866 left homeless, he said.

Frustration is rising across Venezuela over a lack of aid and coordinated government response in areas struck by deadly twin earthquakes, residents in some hard-hit towns say.

In El Junquito, a small ‌mountainous region about 33 km west of Caracas where Venezuelans often vacation on weekends, residents say they have seen few public officials, while farmers and other residents have been providing basic supplies to the community.

“We are waiting for answers, for ‌debris to be cleaned up, for inspections, for people who have been really affected to be helped,” said Keily Ibarra, a 33-year-old manicurist leading citizen complaints to authorities. She called on the government to do “what needs to be done.”

El Junquito’s commercial centre was largely destroyed by the quakes, with collapsed buildings visible during a Reuters visit. Several residents with nowhere else to go have set up tents in an open field, despite the risk posed by damaged and collapsed buildings nearby.

“We don’t know where we are going to be located or how long we are going to be here,” said Tony Abreu, the owner of a local candy store who has been living in a tent since ‌the quakes because his home ‌and business are not safe.

Elsewhere, a hotel near Maiquetia Airport where more than 140 people deported from the United States, including seven children, were staying while being processed ​by Venezuelan authorities, collapsed in the quakes, according to two families of deportees. Most are believed to have been killed.

While several international aid and rescue groups have mobilised to Venezuela, most of the help has been focused in La Guaira, the hardest-hit state of a country long mired in a deep political and economic crisis.

The international community has rallied to help Venezuela deal with the disaster. Authorities said the oil-rich South American country has received support from 30 nations, including 1000 metric tons of supplies, more than 3600 rescue and support workers as well as ⁠118 search-and-rescue canines.
