I want to use a list of names to put in titles of plots or figures.

This is the matrix and the code in my try.

sis = 1; % This defines which element of the sismo matrix element to display
sismo = {'1966 EW Lima'  ;  '1966 NS Lima'; ...
        '1970 EW Ancash'; '1970 NS Ancash';...
        '1974 EW Enero Lima'; '1974 NS Enero Lima';...
        '1974 EW Octubre Lima'; '1974 NS Octubre Lima';...
        '2001 EW Arequipa'; '2001 NS Arequipa';...
        '2007 EW Ica Callao'; '2007 NS Ica Callao'; ...
        '2007 EW Ica'; '2007 NS Ica'};
   sismo = sismo(sis);
figure(sprintf('Numero %s',sismo))

isletter gives the logical values where ever the letter is in your string. Use this is extract only letters and put this as title

clc
clear
sismo = {'1966 EW Lima'  ;  '1966 NS Lima'; ...
    '1970 EW Ancash'; '1970 NS Ancash';...
    '1974 EW Enero Lima'; '1974 NS Enero Lima';...
    '1974 EW Octubre Lima'; '1974 NS Octubre Lima';...
    '2001 EW Arequipa'; '2001 NS Arequipa';...
    '2007 EW Ica Callao'; '2007 NS Ica Callao'; ...
    '2007 EW Ica'; '2007 NS Ica'};
for i=1:length(sismo)
    subplot(3,5,i)
    plot(magic(2))
    %     title(char(regexp(sismo{i},'\d*','Match'))) %title as only numbers
    title(sismo{i}(isletter(sismo{i}))) %title as only letters
end

For figure name, try this,

for i=1:length(sismo)
   figure('Name',sismo{i}(isletter(sismo{i})))
    plot(magic(2))
    %     title(char(regexp(sismo{i},'\d*','Match'))) %title as only numbers
%     title(sismo{i}(isletter(sismo{i}))) %title as only letters
    title(sismo{i}(union(find(isletter(sismo{i})),strfind(sismo{i},' ')))) %is you wish space too in your title
end
