Joanna Torres, who owns Arepas Restaurant in San Jose's Willow Glen neighborhood and San Francisco, is pledging 30 percent of proceeds to earthquake relief after twin tremors — including a 7.5-magnitude quake — killed at least 235 people in Venezuela. Bay Area residents with family in the disaster zone are still accounting for who survived.

The menu at Arepas Restaurant in Willow Glen didn't change after the earthquakes. The revenue will — for the next month, at least.

Joanna Torres, who owns Arepas Restaurant with locations in San Jose's Willow Glen neighborhood and in San Francisco, said she was still processing the news Thursday when she made the call: 30 percent of proceeds at both locations, for one month, would go to earthquake relief. "My heart is still broken," she told NBC Bay Area. "I cannot believe what happened to my country." Torres said her immediate family is accounted for. Others she knows were not so fortunate.

The twin earthquakes struck Venezuela on Wednesday evening. The U.S. Geological Survey reported two back-to-back tremors: the first near San Felipe, about 100 miles west of Caracas; the second, measuring magnitude 7.5, striking only 39 seconds later, near Yumare. NBC Bay Area's continuing coverage put the death toll at at least 235 by late Thursday, with rescue teams still working through rubble in La Guaira — the coastal state declared a disaster zone and among the hardest hit.

For members of the Bay Area's Venezuelan community with family there, the hours after the quakes became a grim accounting. Gladys Aparicio, a San Francisco resident, said her 80-year-old mother did not survive; when a family member went to check on her in La Guaira, the building had collapsed. Liz Jaqueline Bermudez, who was in Venezuela when the shaking began, told NBC Bay Area she was on the seventh floor of a high-rise when the first tremor hit; by the time the second earthquake struck — 39 seconds later — she had only reached the fourth floor.

Two U.S. search-and-rescue task forces, from Los Angeles and Virginia, were en route to the disaster zone Thursday. Harold Schapelhouman, the former Menlo Park Fire Chief who has led teams into Haiti and Taiwan after major earthquakes, offered a blunt read on what comes next. "If it's anything like Haiti, you have a humanitarian problem," he said. "Which means the living don't have proper food, water, sanitation, support, shelter. And that's going to become a bigger problem."

Torres said the pledge at her Willow Glen and San Francisco locations runs for one month.
